Hex I. D. washer source?

Bob · Mar 20, 2018

I need a couple of 9/16" ID. hex washers for a project, 1/8" or 3/16" thick, O.D. not critical.

I thought this would be an "easy find" on the 'net (McMaster, etc.), but all I am seeing are manufacturers selling in large quantities.

Anybody know of a source for a small quantity?

Thanks!

A couple? How about a file.

Any metal shops around that might have a hex punch? I know we can all different sizes/shapes at work. If they have one, they probably could punch them out pretty quick.

I don't mean to side track this but, what are these used for? I had to go search them because I've never seen such a washer. For the life of me, I'm stumped as t why this washer needs a hex hole. Please learn me something.

I'm guessing it needs to turn with the shaft it's on for some reason

I agree that it forces the washer to rotate with the shaft, assuming the shaft rotates. I could see it providing resistance to rotation through friction against whatever surface it contacts. Still curious.

It would be cheaper to buy a case load from McMaster.

Simple version, 3/8" bolt is being used as a pivot point, lever pivoting on bolt has nylon busing inside.

For long life, it's best if the bolt is held stationary and the bushing pivots on the bolt.

A washer with a 9/16" hex ID welded to the structure will hold the bolt from turning and instead the nylon bushing will take the wear.

Start with a 9/16 deep well socket and make as many as you need. Parting tool in lathe would be best but could be done with a drill press and Dremel cut-off wheel.

I think I follow. Thanks

Use an impact socket for the best wall thickness.

Why not just a piece of square stock welded next to one flat of the hex head?
Would do the same thing.
