Chemical-Resistant Vibration-Damping Sandwich Mounts with Stud and Insert
These mounts are made of polyurethane rubber, which withstands exposure to solvents, acids, and oils. Use them to minimize vibration between surfaces inside machinery and equipment, such as in circuit boards, small fans, compressors, and pumps.
58A durometer (medium hard) mounts are tough, yet flexible. Use them in compression and shear load applications.

Load-Rated Threaded-Stud Bumpers
Select these bumpers for applications that require specific load capacities. All are reinforced with a 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 and conveyors. Twist these bumpers into a threaded hole.
Bumpers with a soft and extra-soft rating offer cushioning. The softer the bumper, the more it cushions.
Bumpers with a medium hardness rating offer a balance of cushioning and impact resistance.
Rubber bumpers are abrasion resistant. Those with a soft rating can be used outdoors.
Polyurethane bumpers have better abrasion resistance than rubber bumpers. They won't become brittle and crack when exposed to ozone.

Dual-Clamping Fixture Clamps
Set one of these clamps between two workpieces in a fixture and tighten the screw to push the clamp's sides out for a secure hold. The minimal contact leaves more of the workpieces free for machining.

Low-Profile Fixture Clamps
Install these clamps into a slot in your fixture to grip at the bottom of workpiece edges, giving the cutting tool maximum access to your workpiece. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.
Blunt edge is less likely to mar your workpiece. Knife edge bites into your workpiece for faster and more aggressive machining.
Clamps with brass heads are nonmarring when used with steel and aluminum workpieces.
