Screw rule

See all comments

Torx is the only head that needs to exist. The rest can go fuck a rusty chainsaw.

Square is really good too.

Phillips and flat head bits fit in a variety of sizes of screw heads. We seem to have chosen convenience over performance.

If memory serves me correctly square drive is patented, & thus requires licensing, which is why it's less commonly used.

And then bolts

This is the way. Also I'm new to Lemmy so forever will this be how I start my experience here.

Torx is hands down better in every way than flathead and Phillips.

Slotted heads, Philips, posidrive, torx, 6 pan and Robertson.

Each has a use, for instance a slotted head, when you don't need much torque is good enough (like for a screwed in battery compartment).
