Metric General Purpose Washers
Copper
Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
In addition to resisting rust in wet environments, copper and brass washers are electrically conductive.
Washers that meet ISO 7089, 7091, and 7092 (formerly DIN 125, 126, and 433), meet international standards for fastener dimensions.

Mil. Spec. Washers
Choose these washers for their adherence to strict military standards for material and construction.
Copper and brass washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive. Because of the finish, cadmium-plated copper washers resist corrosion better than copper washers with no finish.

Metal Sealing Washers
Also known as crush washers, these compress when tightened to form a tighter, more durable seal than rubber washers. They are commonly used to seal fluids such as oil and fuel. Washers are not reusable.
Copper washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Brass and copper shims are corrosion resistant and nonmagnetic. Copper shims are good conductors of heat and electricity, so these shims are often used when installing heat sinks.

External Retaining Rings
Open these rings, pass them over the end of a shaft, and release to spring into the groove. Ring ID is measured with the ring uninstalled. Use retaining ring pliers (sold separately) to install and remove rings.
Beryllium copper rings conduct electricity and have excellent corrosion resistance. Do not use beryllium copper rings in direct contact with acetylene.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Side-Mount External Retaining Rings
Also known as E-style rings, these rings have three prongs that make contact with the shaft and provide a wider shoulder than other external rings for a larger retaining surface. Use a side-mount retaining ring tool (sold separately) to push them into the groove from the side of the shaft. Ring OD is measured with the ring uninstalled.
Beryllium copper rings conduct electricity and have excellent corrosion resistance. Do not use beryllium copper rings in direct contact with acetylene.
Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

High-Load Oil-Embedded Thrust Bearings
Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron.
Iron-copper bearings support heavier loads than SAE 863 bronze bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.
