About Durometer Hardness Scales

High-Load Fastener-Mount Compression Springs

These springs handle higher loads than standard fastener-mount compression springs. Secure by inserting a fastener through the hole at the base.

Ultra-High-Load Fastener-Mount Compression Springs

For the heaviest loads, these springs have more than double the load capacity of High-Load Fastener-Mount Compression Springs. Secure by inserting a fastener through the hole at the base.

Fastener-Mount Compression Springs

Differently sized mounting holes on either side allow for mounting flexibility.

Flanged Compression Springs

Flanges on the ends of these springs provide a flat mounting surface.

Bumpers

Load-Rated Unthreaded Bumpers

Select these bumpers for applications that require specific load capacities. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Install them with a screw.

Heavy Duty Unthreaded Bumpers

All of these bumpers are reinforced with an embedded washer or base plate for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines. Install them with screws.

Unthreaded Bumpers

Install these bumpers with screws. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces.

Angle Bumpers

These bumpers are at a 90° angle to protect corners on equipment, walls, and docks from damage caused by carts, vehicles, and other moving objects. Install them with screws.

Bumper Assortments

Keep bumpers of various shapes, materials, and mounting styles on hand to solve whatever problems arise.

Push-In Bumpers

Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.

Tight-Grip Push-In Bumpers

A ridge on the stem provides a tighter grip than other push-in bumpers. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.

Adhesive-Back Bumpers

Press these bumpers into place with the adhesive backing. Use them as feet and spacers on instruments and small appliances to limit sliding, vibration, and noise. They're comparable to Bumpon bumpers.

Load-Rated Adhesive-Back Bumpers
