nominal milspec part, no worries
The washers were about 4 days later than the USPS tacking information - NOT YOUR PROBLEM. Just wanted to let you know whats happening with our postal system.
Very good quality.
These are thin and small washers. If you need a thicker heavier washer use the Baffle seal back-up washers.
Slightly gold anodized finish, but different than steel. Is it just my eyes or do aluminum washers seem thicker than steel? The measurements are the same, however
Regular washer, very flat surfaces. Excellent substitute for AN960 where weight saving is a factor.
