I am wondering if anyone knows what type of washer this is, what they were originally intended to be used for and if they might still be available. Dad used lots of them rigging the 1967 Belmont flat bottom and I would like to get more of them just to keep the boat the way he built it. They are...

I need to get some stringer washers, a bunch of 3/8 ID, but also some 5/16. Any good sources?

I'm looking for 4 or 5 3/8" bolt ones. Anyone have them laying around? Thanks Wags

Anyone know were I can get some 4deg 5/16 washers:)bulb

Anybody buy one and is happy with it? Need it for the dirt bikes and 4x4.
