Any vintage (antique) wrench experts out there? I think its a Williams although it's not marked such, but it is marked "1140" on the side, and there are a lot of Williams with that number. I really don't understand what the symbols are. one end has "1, a hexagon, O, then 3/4 USS. But I measure that end to be 1 3/8" ? The other end has "5/8 USS", but I measure that end to be 1 1/16". ? There is a makers mark or something near the 1140 stamp. The wrench is 12" long, and quite thick. Any thoughts?
This will explain it:
"All of iron worker wrenches used in steel erection are marked with size of bolt not the actual size of wrench opening. Structural bolts have thicker nuts than normal ase bolts. A wrench marked 3/4 actually measures around 1-1/4"
"The formula is the diameter times 1.5 plus 1/8 for those.
So a 5/8 should be 1-1/16 wrench openin"
This is a great website for tools. This may be what you have..
