827 Products

Fastening and Joining

Spacers

Unthreaded to create space between two surfaces or objects, often to align them

Standoffs

Threaded to separate or connect parts as well as position components in assemblies

Washers

Nearly every size and shape imaginable, from flat washers to clipped to curved

Insulating Washers

Insulating Washers

Isolate screws from electrical current and prevent corrosion from mating different metals

Power Transmission

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Flanged Sleeve Bearings

Flanged Sleeve Bearings

A sleeve and thrust bearing in one to support both parallel and perpendicular loads

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Thrust Bearings

Thrust Bearings

Support loads parallel to the shaft with plain, ball, or roller bearings

Building and Machinery Hardware

Bumpers

Absorb impact to protect equipment and surfaces from dents and scuffs
