Why Phillips screws were designed to strip.

Interesting. I’ve noticed that some Phillips head screws handle the torque way better than others I always figured the the El Strippos were from China.

Wow, never knew that. Everyone should watch the video to the end. The rubber band stripped screw removal trick is great - thanks for that!

Heads can have slightly different slot profiles.

Some are dual head pattern with both Phillips and square. The Phillips contact area is weak on those.

Reed and Prince (competitor to Phillips), some out there and some later made to specs "they found somewhere" which are actually R&P.
I've received cheap tool kits as gifts that came with an R&P driver instead of a Phillips.

JIS (Japan Industrial Standard) common in electronics. Not quite Phillips, and Phillis driver won't bite well.

Drivers/bits have different profiles.
I've found a few that work noticeably better than others.

I use valve grinding compound.

We have square drive Robertson screws here in Canada. Used mostly in construction and furniture. More positive than Phillips.

I hate to admit it but those JIS (Japanese Industry Standard) are much better than Phillips drivers. I broke down and bought a set a couple years ago and they don't eat up a screw like a stock Phillips does.

The Japanese screws need a different screw driver. Better to remove the stubborn screws with an impact tool, and replace with Alan head screws. This fixes the problems on the bikes.
For all other work, use a Robertson head screw.
Phillips is the prettiest to look at.

I use the square drives all the time....Philips screws are for the home handyman with only two screwdrivers in his arsenal..... rusty and blunt.

Note I said 'arsenal' ..... re-read that please.

I find that even the Pozi screws are not that good..... the best by far are square drive - or Robertson as they are known in Canada.

Slotted screws are reserved for Dinosaurs who can't handle change.

Like previously mentioned, US and imported Phillips are different.

While working on my 72 Yamaha 100 enduro in the early 70's I learned to hate, ...uh,...well,...despise thoroughly,...and replaced those Phillips with allen head and have avoided the Phillips all I can ever since.

except for the guys who don't realize the bits wear out and sounds like a god dmn beaver working away,that sends me! I once worked with a guy that said the drives were for removing them, he just pounded them deck screws in!

just last week a guy said he was having trouble with the screws on his jap car rotors, i gave him my manual impact driver, when he brought it back I asked if that worked, he said yup took the heads right off! LMFAO

Sounds like BS to me.
