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. Different Screwdriver
  2. Rubber Band
  3. Screw Extracting Pliers
  4. Superglue
  5. Rotary Tool

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。

  • お持ちのネジが潰れてしまいました。ドライバーはもう役に立ちません。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。

  • 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、ネジを動かすように回します。

  • ドライバーの先端から接着剤の残りを拭き取ってください。

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

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.

How would you remove the screw from the driver?

How do I clean of screw driver from the super glue?

And how do I prevent or avoid that situation the next time?

  • ドライバー、プライヤー、ゴムバンド、強力接着剤を使用してもネジが動かない場合は次に回転工具に工夫を凝らしてみましょう。

  • 薄い切断ディスクを回転工具に取り付けます。切断する前に。ディスクがしっかりと取り付けられているか確認してください。

  • 回転工具を使用する際は、破片が飛んで怪我をすることがないよう保護メガネを装着してください。

Mask the area so the small metal particles don't create a short. Even still use a few blasts of can'ed air to blow any junk away.

  • この手順では、潰れたネジ山を薄く切断するため回転工具を利用します。するとネジを取り出すためにマイナスドライバーを使用することができます。

  • ネジやデバイスの他の部分にダメージが入るのを防ぐため、低いパワー設定での使用をお勧めします(私たちは最高が6のうち2で作業を行いました)

  • マイナスドライバーが留ま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。

コメントを追加する

  • デバイスのネジを取り出すためにマイナスドライバーを使用しまし。

    • 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合うはずです。

  • 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製の削りかすを飛ばしてしまうことがあります。

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.

Angel - 返信

OR many you're repairing something with a screw that's already been stripped?

Think outside the box, and don't be so negative.

amuronakamoto -

Uh, there are a number of options here, the rotary tool is given as the last resort.

Marama -

It’s very helpful for me when I repair items that have been badly repaired by other people.

STB Admins -

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

Dan -

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.

Einfacher geht es wenn man eine mutter auf die schraube lötet und es damit rausdreht, aber gutes festes lot verwenden.

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.

Great advice, thank you! :o)

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?

十分感谢Ifixit的指南,帮助我把笔记本散热模块上,一颗滑丝的螺丝去了下来。值得注意的是,在切割片的选择上,我更推荐砂轮切割片,而不是金刚石切割片;它不会产生火花,仅是有一些粉末,对主板的损害更小。

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 !
