Snap-on 3/8" drive, 1/2" crowfoot with a 1964 date code... Spread open, slipped over the bolt, and is now stretched a hair over 1/32" wider at the tip of the jaws.
The ratchet used was a standard-length Proto 5249 (7" long) 24-tooth ratchet, 6" Kraeuter extension, with no cheater.
I realize that the design of a crowsfoot applies torque different than a socket, in that it's not centered on the bolt, but for some good ol' classic USA Kool-aid to fail like this leaves me scratching my head. At no point did the crowfoot engage the bolt at an angle, nor was the force applied to the ratchet in any other direction than rotating perpendicular with respect to the bolt itself. It was firmly seated on the bolt until it spread open and jumped onto the next pair of sides.
Oh, and to add insult to injury, the chrome started peeling, too.
Anybody else had bad luck with these?

Before yesterday I would've said "the price was right" on these when I bought 'em, but after having to disassemble more than I planned on to gain access to that stubborn bolt, my respect for Snap-on dropped a notch or two...
