Have you ever asked yourself why do screw heads keep stripping? The answer is easy if those screw heads are phillips crossheads. Phillips are the ones with the cross and not the single straight edge called a “flat head” or “slotted screws”. Phillips head screws strip easily because that is how they were designed. Bet you didn’t know that their patent is based solely on this one unique feature.
Back in the day Henry Ford had problems with screws cracking his engine blocks. That is when old Henry Phillips designed a new fandangle screw that would strip when the torc exceeded the surface tension of the material being secured. Consequently, the screw would stop before it could do any damage. Since then handymen and women from San Antonio to Timbuktoo have been cursing old Henry thinking that his philips screws and screwdrivers are defective. Put a phillips screw with a power driver and before you can saw Henry F. Phillips the crosshairs will be stripped and you cursing them. Now you know it wasn’t the screw or the screwdriver’s fault. Seems that those pesky little screws are just doing what the venerable Mr. Phillips had designed them to do all along. Mr. Ford appreciated it… probably made him a billionaire more than once..
So the next time that phillips screw head strips on you. Just remember… that is what it is suppose to do!
