I need a 17/32 wrench for the seat-post nut on an English Hercules bicycle. I'd prefer a box, but only find tappet open-ended wrenches in this size. Any ideas? By the way, an adjustable for this application doesn't work; I tried. Vice grips might work, but I don't want to degrade the nut.
17/32 wrench?

What about a socket and ratchet with penetrating oil.
Grind down a Crescent-style wrench?
Typical ignition wrench size of old.

Knipex "wrench pliers." No serrations, so no damage to the nut or bolt head.

13mm is only .014" smaller than 17/32. It might fit.
Several on "Ebay." One made by Mac, one by Craftsman
Don't buy a new wrench, buy a new bolt.
Get one in the same thread pitch that has a findable socket or wrench size.
Would save you the cost of a new wrench, that's for sure. And eliminate future headaches.
You can use that 17/32" bolt as a conversation piece... I guess.

This is the correct answer.
Go to www.mcmaster.com and begin your bolt search. Buy a couple.

Great idea.
...once you get the bolt out.
I agree with the previous posters who recommended a 1/2" wrench and a file. Or find a machinist with a CNC mill who'll massage out a socket for you. I'll do it for a six pack...

Its not a 17/32 its a 1/4 Whitworth.
If you want to change the nut you will need a new bolt also.

Interesting discussion. A 1/4" Whitworth has an identical tap drill size to a 1/4 - 20 UNC bolt (both 5.1mm).

I'd lop it off and buy a 1/4 - 20 bolt to replace. Or even better find a quick release.

1/4W is the bolt head size not the threads, its close to 13.5mm.

Trav, what am I missing - the last 3 charts I've seen indicate the major thread diameter of 1/4 Whitworth is .250"?

I think you are confusing the bolts actual size with spanner size. A 1/4 Whitworth wrench (AKA spanner in many English publications) has nothing to do with a 1/4 inch bolt.
In the article you linked to you can see this with the 5/8 wrench they picture, a 5/8 Whitworth wrench is huge.
I went through this PITA many years ago when i fiddled around with English bikes like AJS, HRD, Ariel, Norton, etc. Whitworth while not the only factor surly contributed to the demise of British machines on the Continent and N.America.
