shared this reaction to my inclusion of Bolt Depot’s PDF reference charts in issue 46
I’m kind of surprised, but some of the Bolt Depot’s chart is wrong, at least where it talks about “stripping” and “cam-out.” It says Phillips and slot-head are prone to “cam-out (stripping),” implying the two are the same. Then it says the hex socket are also “prone to cam-out.”
Cam-out and stripping are not the same. “Cam-out” is where the bit is driven out of the fastener head, because the hole, bit, or both, are slightly wedge-shaped. “Stripping” is where the bit damages the head to the point that the fastener is difficult or impossible to remove.
So yes, Phillips and slot head are prone to cam-out, and sometimes that can cause stripping (though not always.) Hex sockets are easy to strip, but they aren’t prone to cam-out. Both the bit and the hole extend vertically into the fastener head, so there is no force pushing the bit out.
Otherwise, that chart looks handy.
