It was an engineering response to the introduction of power tools in manfacturing.
Slot head tools/fasteners transit too much torque which often resulted in the fastener heads shearing off when used with power tools.
Rather than build a complex torque limiter into the tool (which would need adjustment based on use case), they built it into the fastener.
- bartread 4y agoWould definitely have made sense back in the day. Nowadays most cordless drills, even cheap models, have that exact torque limiter mechanism built in so you can dial in the torque you need with a simple twisting collar - use it all the time. I hate Phillips Head screws, second only to flat head screws. They're "fine I guess" for some low torque applications, but even here they're not great. Was at GF's house the other day trying to screw through 18mm ply with some Phillips screws, which were all she had in the length I needed. Couldn't even get them through one sheet with predrilled pilot holes without them camming out and stripping the heads. Awful. Ended up making a trip to Screwfix to get some posidrivs.
