I found this on the street between a nice apartment building and a chi-chi shopping center (Fidelity has its office in it), up the street from Trader Joe’s (I was on my way home from a shopping trip.). It’s 12-point. I measure 1 3/16" between notches, which makes it a 1" wrench. It’s broken by force…

I’ve never broken a wrench outright, but I’ve badly damaged both the wrench & a fastener by adding a length of pipe to the wrench handle for extra leverage. 1 inch wrench? hmmm… I thought that meant it measured one inch from flat surface to flat surface, the surfaces being 180 degree apart. Does…

Can you look at the crack and tell where it started?

[image] RandomTroll: I’ve never seen wrenches in the 32nds It’s not the wrench that’s measured in 32nds, its the measurement between opposite points of the hex pattern. I can see however that it would be difficult to measure the inside dimension of a 12-point socket to that sort of preci…

Maybe broke while being used outside in bitter cold or due to the metal being crystallized in that area for some reason.

I’d hang onto it but I’m also a pack rat. Those broken pieces of tools can end up very handy when making a specialty tool.
