Slide these shims under the screw head to shorten the shoulder length.

These thick washers are designed to support structural screws, studs, and nuts.

Reinforce holes in soft material to keep them from collapsing around screws.

Designed for use with bearing nuts, these lock washers have a conical shape that presses like a spring against bearings, bushings, gears, and pulleys to hold them in place on your threaded shaft or spindle.

These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws.
