Washers and Shims

Washers serve to minimize embedding, aid in torquing and to distribute loads over alarger area of lower strength material. ASME B18.22.1. Washers can be unhardened as per ASTM F844 or hardened as per ASTM F436.

Bonded Washers

Bonded washers or sealing washers are used in applications that require a stronger seal than conventional washers might provide. Bonded washers are slightly conical metal washers with a bonded neoprene or EPDM rubber backing. They are available in steel and stainless steel and in a range of sizes. Bonded washers are commonly used in roofing and plumbing applications.

Flat Washers

A flat disk, as of metal, plastic, rubber, or leather, placed beneath a nut or at an axle bearing or a joint to relieve friction, prevent leakage, or distribute pressure. SAE pattern flat washers tend to have a tighter fit on the bolt/screw and a smaller outer diameter than USS pattern flat washers. Fender washers are flat washers that have large outside diameters relative to their inside diameter.

Lock Washers

Helical spring lock washers or split lock washers are available in a regular, heavy, extra heavy and high-collar design. Tooth lock washers follow internal, external, internal/external and countersunk external designs.

SAE and USS Flat Washers

S.A.E. Flat Washers were developed and specified by the Society of Automotive Engineers to meet the requirements of automotive manufacturer applications as boradly as possible. They are of smaller Outer Diameter and thinner guages or thickness than their counterpart bolt sizes of USS Flat Washers.

United States Standard or USS Flatwashers were developed to satisfy engineering requirements in the majority of industrial applications in all fields of manufacturing, maintenance and repair. The Outer Diameter (OD), Inner Diameter(ID) and Thickness (Th) specifications were developed to meet the broadest possible number of applications.

Shims

Shims are thin pieces of material, such as wood, stone, or metal, used to fill gaps, make something level, or adjust something to fit properly. Shims may or may not contain a center hole.

Special Washers

This category includes the following washer types: Cup Washers, Odd Shaped Washers, Tab Notch Washers, Shoulder Washers, Inner Race Spacers and Outer Race Spacers.

Spring Washers

Spring washers are disks of metal that are formed in an irregular shape so that when the washer is loaded it deflects, acts like a spring, and provides a preload between two surfaces.  Spring washer types include adjustable spacers, Belleville washers, bowed or curved washers, conical washers, finger washers, and wave washers. Spring washers are typically used in applications where assemblies need a part to take up play, eliminate rattle, maintain assembly tension, compensate for expansion or contraction in materials after assembly, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.
