I have no idea what kind of bolt this thing is, but we need one for the Fry 117 that we are going to work on after we finish the Erie 71. It's the only bolt that isn't there.

The threads are 5/16NC18
The head takes a 1/2" socket.
From the bottom of the head to the tip of the threads is 1"

Now the weird part -- the head on this thing is 5/16" thick, and it is rounded over on top.

Does anyone out there have one of these animals?

Thanks!
Chris

They were used on old cars also, if you cann't find one here check with some one that restores Model A's or T's. Richard

Can't believe your school has a body/paint Shop & Not a Machine Shop? Another Class Project!

Man, I wish that was the case!

All we really have is a woodshop that doubles as a welding/autobody/paint and auto mechanic shop that can be converted to a paintbooth with 10,000 tarps spread around all over the place!

If we had a metal lathe, your're right, that would be a good project!

That makes sense, but NOT IN a WOOD Shop. Your Principle/President needs to be Replaced, maybe w/ a Queen!

I have some out of an old pump but mine measure 1" overall / 3/4" bottom of head to end of thread. 5/16 18 (coarse). They also have some oversize nuts on them. I probably have a dozen or so if it will help.

Someone on this site(in the last year) posted about a source of the rounded, thick headed bolts used on Fry pumps. They also gave the name of the bolts.They were expensive..4 or 5 bucks apiece. Any info would prevent me from losing what sanity I have left...THANKS in ADVANCE....Dave
