Frequently asked questions
Which bolt size does this washer fit?
It is designed for M8 bolts, whose shank passes through the 8 mm inner bore.
Does a flat washer prevent a bolt from loosening?
No. A flat washer distributes load but does not lock the fastener. For vibration, use a lock washer or a nylon-insert lock nut.
