Exactly what I was looking for for a special project I was working on. perfect dementions and material for a perfect price
exactly, what is needed, for the job.
I use these as back up washers for -4 (1/8) rivets. Hole is a little tight so I push the washer onto the rivet with a small socket driver. Much neater that the standard backup washer.
Best price around , we buy thousands of these a year !!!
