One of my greatest annoyances are cross head screw types. You probably just call them Phillips and use the same screwdriver on all of them. You You are wrong.
Part of the problem is Phillips are designed to strip at low torque to prevent assemblers from tightening them too much and causing damage.
Phillips also come in different sizes, the sizes are not compatible and using the wrong one will cause the screw to strip.
Then, it might not be Phillips at all. Here is an incomplete list of semi compatible screw types you might encounter.
Phillips
Pozidriv
JIS
ISO 8764
Supadriv
Phillips II
Frearson
French Recess
Mortorq
ECX
Between these three points, these types all end up getting stripped and creating a massive maintenance headache.
I own a couple hundred dollars in tools just for stripped fasteners. None of them work. I have to carry tons of different bits and screwdrivers to still have constant problems with these.
If you design or build anything that uses any of these screw types, I hate you only slightly less than the people that still choose flat head screws.
