Customer Reviews (4.8 / 5 · 5 reviews)

Lily X. ★★★★★

Used a full bag on a motorcycle skid plate and they held tight through a 200-mile shake-down. The black oxide coating seems properly done, no flaking when torqued down. Can’t beat having a thousand on hand for the price.

George ★★★★★

Used these for a vibration-prone mower deck repair and the black oxide finish held up nicely against rust during installation. Each washer gripped the bolt head firmly with those external teeth, exactly what I needed for a secure fit.

Ryan ★★★★★

Was rebuilding a small engine mount and these lock washers grabbed tight right away, the black oxide coating looks clean and professional. Held up perfectly during a test run with plenty of vibration.
