I’ve found a couple that just didn’t seem to be snug enough from the start. Like 6 hex screws on this bike trailer thing. 5 of them fit a 6mm hex wrench perfectly, but on one it just spins and the next size up was too big. Either it wasn’t to spec or it warped at some point or something. I think other fastner heads would be more forgiving in this regard.
Robertsons are the Pinnacle screwhead. Torx and hex are also acceptable
Not Hex, I’ve stripped those a few times.
Yeah, hex is only a few obtuse angles away from being a circle. And that means it strips into a circle surprisingly easily.
When a hex goes circle it’s time to break out the triple squares and a hammer! Poor man’s extract set lmfao
