Hex Key, Allen Wrench, L-Key, no matter what name you call it, if you have ever assembled anything you have probably used one. You can get them in Metric or SAE and they come in all kinds of sizes, from the tiny .028 inch to massive one inch. They are commonly used for furniture assembly because they are cheap to manufacture and can be tossed in the box for the customer to use (evidently they are like paperclips at IKEA and they will give you one if you ask nicely).
We have grown so accustomed to getting free L-keys in our furniture boxes that we take for granted the inferior quality of them and are very likely just to throw the tool away with the plastic bag it came in when we’re done. As any reader of this blog should know though, we buy good quality tools and demand only the best, so why use that freebie in the first place? A good set of L-keys will last you decades without showing wear and tear. But there is one big advantage to buying a quality set of L-keys and that’s the ball end.Read More »
The confusion doesn’t stop there, though. In 2009 Apple launched the pentalobe screw, and that’s about all they did. There was no regulatory sizing so the brains at iFixit reverse engineered the screw and made a driver to work with it. Since it was similar in size to a Torx T2, the called it a P2. After they did this, Apple released sizing information and revealed that iFixit’s P2 was actually a size 1. It was after all this commotion that WIha released their set of pentalobes (to Apple Standards), so their PL1 is actually the same size as iFixit’s P2. Did you get all that? To keep things simple (and since this is the GERMAN tool blog) we will use Wiha’s sizing standard, PL1-PL6.
