I wish someone would fix this thread. It’s annoying because it shows up as the no.1 search result for ''‘Philips equivalent for P5 Pentalobe’'' and marked ‘SOLVED’. Neither of which is the case.
The thread title doesn’t actually mention that the original poster is looking for Philips equivalents/replacements for Pentalobe screws [it just says ‘replacement screws’]. The Philips aspect isn’t mentioned til the body of the post. And the ‘SOLVED’ answer just tells where to get replacement Pentalobes, which 30 seconds on eBay or Amazon would tell us anyway.
In addition there is advice for people to measure some existing P5 pentalobes with a caliper to get the correct dimensions / thread pitch, etc. But, as is often the case on the intarwebs, if anyone did this, they’ve not bothered to return and share with the rest of us.
I’ve also been trying to find the dimensions of the P5s so i can replace the ones on my MacBook Air with Philips screws and haven’t had much luck so far. I did find a seller on AliBaba offering replacement sets of pentalobes who had thoughtfully provided some sizing info. So here is what they put [I can’t vouch for its accuracy]:
* 8 x P5 pentalobe screws - 2.6mm in length, 0.4mm thread pitch
* 2 x P5 pentalobe screws - 8.9mm in length, 0.4mm thread pitch
* [Diameter wasn’t given. Can it be inferred from the thread pitch, I wonder?]
I’ve also found that some tiny Philips screws I had kept from an old MacBook Pro [pre Unibody model] worked to replace the 2,6mm long pentalobes in my MacBook Air. So I have swapped those in. I’m still not having much luck tracking down a Philips equivalent for the two longer screws though.
Will report back if I ever crack this.
