Oversized Washers

Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses for covering oversized holes or for use as spacers and levelers.

Metric Oversized Washers

Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.

Mil. Spec. Washers

Choose these washers for their adherence to strict military standards for material and construction.

SAE Washers

SAE washers generally have a smaller ID and OD than USS washers.

ASME Washers for Soft Material

Also known as Type B washers, these distribute your fastener's load over a larger surface area than other washers to minimize damage to soft materials.

Metric Finishing Countersunk Washers

Clipped Washers

Clipped to fit where standard washers can't, these won't rotate when you position the flat edge against a flat surface.

Oversized Clipped Washers

With greater diameters and/or thicknesses than general purpose washers, these washers cover oversized holes or act as spacers and levelers. Clipped to fit where standard washers can’t, they won’t rotate when you position the flat edge against a flat surface.

Double-Clipped Washers

Clipped on both sides to fit where standard washers can't, these won't rotate when you position the flat edges against a flat surface.

Square Washers

Square washers fit into slots and channels and have flat sides to keep them from rotating.

Sleeve Washers for Soft Material

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

Easy-Install Slotted Washers

A slot in the side allows you to install and remove these washers without completely disassembling your joint.

Wedge Lock Washers

Comparable to NORD-LOCK® and Sherex TEC Series washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting.

Tab Lock Washers

Bend one tab against the side of the mounting surface and the other tab against the flats on a bolt or nut to prevent both the fastener and washer from turning and loosening in high-vibration applications, such as a motor mount.
