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 !!!
Exactly what I needed excellent quality and price plus the shipping was reasonably for a change.
Perfect fit for what I needed. Quick delivery too.
This size washer is hard to find. Thank toy for helping me out !
Common aircraft grade/specification fastener.
