Keep shim stock in a variety of thicknesses on hand with these sets. Cut into custom shapes to fit your application.

As a screw is tightened, these metric washers flatten to add tension to the joint, counteracting fatigue around the joint from small amounts of vibration.

Teeth on the outside edge of the washer bite into the screw head and joint for a tight grip.

Internal teeth dig into the screw head while the smooth outside edge won't snag objects. Use with fasteners that have small heads, such as fillister and cheese head screws.

These curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.
