はじめに

ネジ山が潰れたネジはどんな修理ファンにとって厄介な問題です。ネジによっては取り外されたくないものがありますが、できる限り最善を尽くしてみましょう。作業を始める前に伝えておきます。ネジ山が「+」が「O」も変形するため、フラストレーションに包まれます。この手順ではネジ山の小さな切り目を切断して、マイナスドライバーでネジを取り出せるようにします。

テクニック:

  1. 違う種類のドライバー
  2. ラバーバンド
  3. ペンチでネジを引き抜く
  4. 強力接着剤
  5. 回転工具

回転工具を使用する際は、破片などが飛び散って怪我をしないように保護メガネを装着してください。

  1. 目の前のネジ山が潰れてしまいました。ドライバーではもう対応できません。打ちたたいて壊す前に次の手順を試してみましょう。
    • 目の前のネジ山が潰れてしまいました。ドライバーではもう対応できません。打ちたたいて壊す前に次の手順を試してみましょう。

    • これまでとは違うドライバーを使用します。まず潰れたネジ山の一部分でも動かせるか確認するため、わずかに小さいか大きいヘッドサイズのドライバーで試してください。それからマイナスドライバーでも試してみます。

    • すぐにビットがネジを掴めない場合は作業を中止してください。さらにネジ山を潰してしまうことになります。

    • 上記のアドバイスでネジが動く場合は、おめでとうございます!ネジは取り出せます。

  2. ラバーバンドを使うとドライバーを回転するのに必要なグリップ力が強化されます。 ラバーバンドを伸ばして、潰れたネジ山の上に載せてください。 ネジ山に合うドライバーを差し込んで、回します。

    This didn’t work since I used a small rubber band. I’m trying to remove the right screw from the optical drive. It’s already stripped and I’m planning on using the super glue which I’m deeply unsure of doing. I was thinking about using the #00 Philip screwdriver to add the super glue on. And I’m not sure if that worked for anyone especially if it didn’t snapped off. Any answers?

    This part should be removed from the guide - it doesn’t work at all.

    • ネジ山にアクセスできる場合、ネジプライヤーを使用してください。ネジが掴める場合は旋回させるとネジが外れるはずです!

    • ネジが少しでも緩くなったら、残りの作業はドライバーで外せます。

    You can make your own screw extracting pliers using a file and old pair of regular pliers.

  3. まだネジが動きませんか?この場合は、ネジ山に強力接着剤を流し込みます。 ドライバーをネジ山に差し込んでそのまま接着剤が乾くのを待ちます。 ドライバーを下向きに押し込むようにしてしっかりと握り、ネジが動くように旋回させます。

    You might want to mention to spend the extra buck and get the gel superglue. It's way easier to control...

    lkmemphis - 返信

    Also might suggest applying the tiny ammount of super glue to the tool tip not the screw. If you accidently squeeze out too much the overflow can be cleaned off the tool and the glue reapplied much easier than it can be removed from the screw and the surrounding areas of the device. Alternately the surrounding areas can be masked from excess glue with a bit of transparent tape.

    Can we reuse the screw afterwards? I have my macbook pro 2.9 mm T3 Torx and 1.7 mm T3 Torx screws stuck but couldn’t find those screws to buy…

    Camille Le Men - 返信

    If the screw is stripped, why would you reuse it? You’ll have the same problem when trying to repair the Mac in the future if you need to repair it again. Don’t they have those screws available as a kit (with other screws) on iFixit?

    Likely the screw shavings are magnetic, so passing a powerful magnet may help collecting the screw “dust”. Especially important if the circuit board is not con formally coated as this “dust” is definitely conductive.

    Larry Jay - 返信

    Was going to post the same comment- absolutely agree that you should protect the device from conducting dust- could easily get lodged between IC pins, especially as magentised through grinding and would stick together in a sort of string.

    I. Margaronis - 返信

    If you're worried about conductive dust, then put the phone on its side and blast it with alcohol and a makeup brush.

    • マイナスドライバーが装着できるようにネジの深くで切断したいと思うかもしれませんが、この薄さで十分ドライバーが固定します。

    • 潰れたネジ山のネジの先端を薄く切断してください。

  6. ネジを取り出には、マイナスドライバーを使用します。
    • ネジを取り出には、マイナスドライバーを使用します。

    • ドライバーのサイズはネジのサイズによります。しかし一番大きいサイズは切断した部分にフィットするはずです。

    • 切断部分にドライバーがうまく合わない場合は。回転工具を使って、切断部分をより大きくしてください。小さく切断するだけで結構です。もしネジ山を大きく切断してしまうと、ドライバーが止まらず、ネジを回すことができなくなります。

    • 再組み立ての前は必ず保護メガネを装着してください。回転工具がデバイス周辺にメタルの削りかすを飛ばしてしまうことがあります。

    What to do if the screw is much deeper inside?

I usually use the soldering iron, resting on the screw head dilation of the materials or any glue on the thread, but if the damage the screw head is large only with the idea of ​​same rotary tool.

Cleyton - 返信

"To reassemble your device, follow these instructions in reverse order."

Yeah, that makes perfect sense... If you put the saw in reverse it glues all the buts of iron back onto the screw :-)

But other than that, this could be useful in some situations. Be careful,of the iron filings on your electronics!

koesper - 返信

Haha, good catch! We've fixed the conclusion. Apologies to all who tried so very hard to follow these instructions in reverse.

Jeff Suovanen -

You could also try Bit-Biter. The unique formula multiplies friction between a slipping driver and fastener head, creating enhanced gripping power during installation and removal processes. Stripped, rusted, or damaged fasteners and drivers become workable again! http://bit.ly/19PJn3w

There's always the ultimate tool if it won't go out, the drill.

Of course you'll have to make new threads if you drill out a screw. However, as a "weapon of last resort", the drill always works.

Branko Dodig - 返信

Thank you for this guide. The Vampliers, however, completely removed the head of my T6 screw. There are two of them holding the display to the top case of my 15'' Macbook Pro. I am on one of the last steps in the Top Case replacement guide.

Can I use a drill if my screw has virtually no head?

Thanks!

A Mac User - 返信

Using the rotary tool will spray metal filings all over the electronic components creating a short. Bad idea.

Brick dal - 返信

I agree, to a point.

But listing it as a last resort, for a device that is already broken and cannot be repaired until the stripped screw is removed, does fit this article. Metal shavings aren't making something that is already unusable worse off. Your observation that there are risks is probably something the article should mention though as part of the explanation for why this was listed last.

toddgardiner -

Thanks for mentioning this! We added a cautionary note to the last step, reminding readers to blow out the device with compressed air before reassembly. That should help reduce the risk from loose metal shavings.

Jeff Suovanen -

This didn't help at all. In fact rubber band and glue made it worse. I don't want to use a drill. Not when the screw is so tiny. It can create more damage to the system

The rubber band trick worked like a charm for me! I couldn't remove a sunken stripped and rounded out philips head from my tail light to change the bulb. I thought I was going to have to go to a shop to get the bulb changed. I tried the rubber band idea with no real expectation of it working and surprisingly it did.

Give it a try and it might just work for you too!

absoluteze - 返信

Came up with a better solution for the first or second try. Personally, I would do this first. The Story: Had a Canon G16 with a stripped screw head. Severely rounded phillips, appeared that wrong size driver was used. I noticed after a bit of inspection that my good screw driver was bottoming out, preventing any contact with any remaining slot. There wasn't much remaining slot at all. I filled off the point of my screw driver just a small amount but that let me "find" the remaining phillips head slots and with some strong pressure was able to turn the screw out. Worked great.

Stihl Working - 返信

thanks for taking time to post this helpful information!!! thats very nice of you and i appreciate it very much. even if it ends up not working in my situation , which im sure one of these steps will

WARD KNIGHT - 返信

My screwhead is not stripped, the Screw just spins. What do I do to get it out, can't grab head either

LuAnne Biskup - 返信

See if you can slide a thin knife blade under the screw head and then carefully try to unscrew the screw (don't apply do much downward pressure here), as you turn the screw lift the knife edge easing out the screw until you can grab it.

Dan -

Hand operated micro drill, using a bit which is the same size as the hole the screw goes through. Just drill until the head of the screw pops off, clean up filings with a magnet. Once you've removed the part you can use pliers to remove the headless screw.

Tim Lockwood - 返信

I think you're talking about a jewelers hand drill (or pin vise) like this one: Jewelers Drill

This seems to be all regarding electronics. I have two screws that are stripped that hold small brackets on a wall. Previous owner of my home seemed to strip many screws. These screws are phillips and to top it off are not screwed in straight. I am remodeling my kitchen by myself and i am trying to repair all the holes in the wallboard. I would guess grabbing onto them with pliers might be the best idea. Any thoughts?

Deborah

Deborah - 返信

Pliers should work! That's probably what I'd do. If you have trouble, there are screw extracting pliers made just for this purpose.

Jeff Suovanen -

what if the screw is stripped and inside a whole like a Nintendo 3ds and cant cut it and glue or rubber band didn't work??

victor - 返信

exactly the problem i have. I even sent it to Nintendo, they sent it back and said Nope.

joey c -

See Tim Lockwood's comment above. When all else fails, a drill will get the job done. It can be a bit messy, so I usually use it as a last resort.

Jeff Suovanen -

See the problem is that I'm like poor. And when I say poor I mean broke. I don't have any fancy tools (rotary driver? nope!) and I really just want to take out the battery of my phone before I fix the screen since I'm waaaaayyy too cheap to buy a new phone and I don't want to die. Is there a cheap effective way to remove it (I tried all of the above except super glue, I don't have that either and won't be able to get any) I really don't care if the screw is destroyed since I have a second one anyways. ( I also don't own a drill)

Help?

Niels de boer - 返信

Thanks for this guide. I didn't have a rubber band so I used some kitchen paper, and it worked. I guess anything that's thin, soft and have a descent amount of friction will work.

More Easy to use soldering new Srew on the demage screw .

You need good soldering tin

christian - 返信

Yet one more idea that might work is a trick I sometimes use on larger seized fasteners on cars. Using a very sharply pointed punch (like a sturdy nail which has been sharpened) and a small hammer, make an indentation in the screws head out close to the edge (hold the punch vertical for first few taps) then tilt the punch about 45 degrees and while keeping the point in the indentation tap in the correct direction to unscrew the fastener. Repeated impacts will unscrew the fastener.

So, you get the screw out, now what? How do you get another screw to hold in a flogged out hole? Does anyone have any ideas?

Rohan Ward - 返信

If you don't NEED to put a screw there, don't. However, if the whole thin g you are taking apart will fall apart if you don't than drill a new hole in the same spot to give its shape back

Hi,

on a very small stripped screw (inside a mcbook pro) i tried the rubber band trick and the pliers one, without success. i remembered i bought a normal’ sized screw extracting kit (3 bits, this type: https://fr.aliexpress.com/item/New-4pc-H...) and gave it a try, even though the bit looked huge for the screw.. but it worked perfectly !

allowed me to finish mounting that ssd in place of the dvd drive in the macbook pro mid 2010.

Thank you for this very helpfull post !

I tried the rubberband method on a semi-stripped tri-wing screw, not expecting much. Wha’dya know, that did it!

Jose Olarte III - 返信

This isn't helpful. If you can't afford a decent screwdriver in the first place chances are you won't have a rotary tool handy? maybe think of something a bit more practical.

How can you not afford a dollar for a screw driver?

Anyways next question, anyone know of a tool that's shaped like a “scapel” and that can grind down to create a star screw driver slot?

I find that this is most practical as it can be attached to your keyring & therefore almost always with you.

Brandan Hepi - 返信

Great video but after the cut on the screw you MUST blow out the metal waste remnants of the cut or it will short out the circuit board as soon as its activated…..

Don - 返信

I like the glue tip, i had not see that before. Definitely, implement these in the order above and avoid the Grinding wheel if possible.

Leaton - 返信

Not mentioned, and I read all, instead of the screw extractor pliers, cheap ‘ol me has used a pair of vice grips MANY times. I even got a a set of security screws (the ones that you can only tighten) out this way. They make several different sizes of vice grips.

To prevent problems I suggest only using good high quality screw drivers to begin with, nothing from your local grocery store, Walgreens, cheap discount stores.

Paul - 返信

If you don’t have rotary tools, a hacksaw still always works.

Oh yeah! These are perfect for removing those extremely annoying security screws or others.

Rather than the super glue (which is essentially plastic) I recommend metal (soldering)

Yeah. With a few bits of solder (and a soldering iron + a iron fork) you can extract 99% of the screws (no one makes aluminum screws)

that’s a good one. I will note that.

Xavier Jiang - 返信

The screw that is stripped is in the back of a watch which is slightly sunken and very small. I have tried the rubber band and that did not work. I’m thinking my last resort is the superglue. I would be willing to break the back off and buy a new one if I could figure out how any suggestions.

I would love it if you could leave a comment at my email address pinhigh353@yahoo.com

All suggestions accepted, thank you.

Annie - 返信

This was real handy for me. Ended up using the super glue method with a home-made prop on my MackBook’s stripped keyboard screws (the 66 tiny ones of course). Took a cycle of about 14 hours for each of the 10 stripped screws, but they’re all out. What a nightmare that was. Rusted and stripped screws are a horrible thing to deal with.

Tony - 返信

Also if the screw is sticking up part way you can put the head of your drill around the head of the screw and clamp it down like a drill bit and put it on reverse. I just did it and both my screws came right out!

grovelandwolfs - 返信

the screw I'm trying to get is in a little hole and I can't get at it with these methods. Any ideas on how to get it out?

Kyle Hoyer - 返信

One of the screws in my Mid 2012 MacBook Pro were stripped, and I used all of these techniques save for the super glue and rotary tool. I did however, use a drill which allowed me to get past the stripped screw. Using a drill is going to be dangerous however, because you could drill through the entire device, damaging it beyond repair. You have to be very careful, and only drill until the head of the screw comes off, then you have to use the pliers to finish removing the screw.
