Big wrench

admin

I was given this wrench a long time ago. Just wondering if anybody can tell me anything about it. Measuring the open end comes to 1 3/4", even though it says "1" by it. I'm thinking that means the size structural bolt, maybe?There are six characters. The first kinda looks like a "C" and the second looks like the "&" . The third looks like maybe an "E" or an "F". I forgot to measure the overall length, but I would guess around 24". I can take a pic next to a tape if it would help."Where's Stick man????????" - 7A749"SHHHHHH!! I sent him over to snag that MIC-4 while tbone wasn't looking!" - duaneb55"I have bought a few of Tbone's things unlike Stick-Man who helps himself" - TozziWelding"Stick-man"
Reply:Do the marks on the handle look like they were placed there when manufactured, or like punch marks?  Almost looks to me like they're punched for someone to ID them.The mark which may tell you something what looks like a makers mark at the end.  Looks like a shield with something in it.  Letter H, or A maybe?

Reply:Morning Stick,If a close examination with a caliper shows it is closer to to 1.67 it would be a BSW (British Standard Whitworth) wrench for a 1" capscrew or nut. Old Jaguar lovers would go la-la over it among others.If it were a bit less than 1.5" then it's BS (British Standard).Confusing? This all goes back to being a global power and the size of the commonwealth so it worked pretty good. Whitworth theads are still used for camera mounts (all of them).MattLast edited by Matt_Maguire; 06-12-2011 at 07:23 AM.
