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.
Stainless steel shims are more corrosion resistant than steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.

Compressible-Stem Push-In Bumpers
The stem on these bumpers compresses to fit into tight holes. 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.
Bumpers with a medium-hard rating withstand higher levels of impact than softer bumpers. Bumpers with a medium-soft rating offer a balance of cushioning and impact resistance.
SBR bumpers have good abrasion resistance.

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.
Bumpers with a hard and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
SBR bumpers have good abrasion resistance. They are not for use outdoors.
