Washers

General Purpose Washers

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.

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.

Washers with Material Certification

These washers come with a traceable lot number and a physical and chemical test report.

Split Lock Washers

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Mil. Spec. Split Lock Washers

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

Oversized Split Lock Washers

Compared to standard split lock washers, these are thicker and have larger outside diameters.

Retaining Ring Assortments

External and Internal Retaining Ring Assortments

Assortments include pliers to install external and internal rings.

Side-Mount External Retaining Ring Assortments

Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface.

External Retaining Ring Assortments

Pull these rings open with retaining ring pliers, pass over the end of a shaft, and release to spring into a groove.

Internal Retaining Ring Assortments

Pull ring ends together with retaining ring pliers and place into the bore of a shaft or housing.

Retaining Rings

External Retaining Rings

Open these rings, pass them over the end of a shaft, and release to spring into the groove.

Heavy Duty External Retaining Rings

Thicker than standard external retaining rings, these rings withstand greater force.

Self-Locking External Retaining Rings

No groove is required for these rings—their thick profile helps them grip the shaft.

Push-On External Retaining Rings

No groove required—press these rings onto the end of a shaft for a firm grip.

Side-Mount External Retaining Rings

Also known as E-style rings.

Heavy Duty Side-Mount External Retaining Rings

These rings are reinforced to withstand faster rotation than other side‐mount retaining rings. Also known as reinforced E‐style rings.

Low-Clearance Side-Mount External Retaining Rings

Also known as C-style and crescent rings, these rings have a small shoulder to fit in tight spaces.

Internal Retaining Rings

Squeeze these rings to place them in the groove inside a bore or housing.
