Washer - Internal Tooth Lock, Steel, Black Oxide

Starting at: $0.39
Package of 5
Sold as a package of 5

Black oxide finished steel lock washers that use internal teeth for locking and tension. The internal teeth dig into the screw head or nut while the smooth outside edge won't snag objects. These washers provide greater vibration resistance than split lock washers. Black oxide lock washers like these can be found in vintage Marshall amplifiers.

Pairs nicely with S-HSB4-X, S-HSB6-X, and S-HSB8-12 screws and S-HBNX nuts.
