Round Shims & Arbor Shims

Available533 products

Round shims and arbor shims, sometimes called slitter shims, are washer-like shims that help reduce the axial movement of components on a shaft or rod. They are made with specific metal formulations and machining processes to ensure an exact fit. They are commonly used to space out components on machinery arbors such as saws and grinding tools.

Lengthening Shims for Shoulder Bolts

Lengthening Shims for Shoulder Bolts

Lengthening shims for shoulder bolts fit around the stripper threads of a shoulder bolt and sit against the bottom of the unthreaded shank. This raises the point at which the female fastener bottoms out, effectively lengthening the bolt to a non-standard length. They are commonly used in repair and manufacturing applications to ensure tight tolerances.
