I know we’re all volunteers here, but i’m a little frustrated that the answer by Mayer is voted as “Chosen” and Dan as “Most Helpful” when they are quite far from answering the OP’s original question. Pentalobe is a horrific design. It strips easily and is designed to annoy all of us here. To replace these screws with something better like phillips or torx, you can buy the screws from a site like https://www.laptopscrews.com/ and https://www.metricscrews.us/ And no you don’t need to purchase 50,000 screws. You can purchase the exact amount you need at a very affordable price. The only thing is, you’ll need to measure the thread depth and pitch using a ruler or maybe a caliper. The websites above will explain how to do that.
