Which engineering screw up was/is worse? The C6 ZO6 valve issue or the GT350 blown engine issue?
I was going to say the Tacoma Narrows Bridge. Or possibly the Hubble primary mirror. I see now I was going in the wrong direction on this.

LMFAO! Nailed it.I was thinking carpet in a garage, so don't feel too bad.

The Phillips-Head Screw
Worse than the worthless slotted design? I'll take a Phillips all day over a slotted.

For real though......
Mixing metric and standard fasteners in the same equipment.
Well, you could say Challenger was not an engineering screw up. If they had listened to the engineers, it never would have been launched. And Columbia was more a political screw up. The foam failed because the brass insisted a new foam be used because it was "green." I do see your point, though.Therac-25

Torx is best. When I install a puppet ruler of the world, the first thing I'm going to have him do is make a law banning everything but Torx.Phillips isn't bad if you get the correct number bit to match the head profile. It's harder to strip a flathead with the incorrect bit than a phillips. The worst auto-feed systems I ever worked on were phillips. Torx is my favorite by far.
And what profile do we grind into a phillips when we inevitably strip one out by looking at it the wrong way? One big slot.

They need to invent a new method of torture for engineers that do that crap. I fired a guy one time who kept doing that out of sheer laziness. Our engineering standards dictated metric fasteners, but our CAD system had SAE as default (we kept requesting PTC give us an option to change it). This dingus would only use metric if it was already established in a model, so we had M6x1 here, 1/4-20 there. Sometimes he'd sneak in a fine thread, or somehow managed to get non UNC/UNF threads altogether. I stuck him on detailing duty until he pulled two stunts on the same day and I had to let him go.
