About Durometer Hardness Scales

Inch-to-Inch Female Hex Thread Adapters
Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench. The threads on these adapters have various sizes and spacing, so you can increase or decrease thread size or adapt from coarse to fine threading. You can also use them to change the gender of a connection from male to female. Small adapters can work as threaded standoffs, which position and separate circuit boards and other components in assemblies.
18-8 stainless steel adapters withstand wet environments but will corrode when exposed to salt water and other chloride solutions.
316 stainless steel adapters are ideal in wet environments and will not corrode when exposed to salt water or harsh chemicals.
Aluminum adapters are about one third of the weight of steel adapters and resist corrosion in wet environments.
Adapters that meet ASTM specifications are made from or plated with materials that adhere to standards for chemical and physical properties, such as hardness.

Removable Drill Bushings for Thin Metal
Unlike most bushings, these won’t buckle the material or distort the hole when installed in thin-gauge aluminum and steel plates. Insert them into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in place by a lock ring (sold separately).

Heavy Duty Threaded-Stud Bumpers
All of these bumpers are reinforced with a steel core 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. Twist them into a threaded hole. All are nonmarking and can be used outdoors.
Bumpers with a hard rating withstand high levels of impact. Bumpers with a medium-soft rating offer a balance of cushioning and impact resistance.
Neoprene bumpers have good abrasion resistance.
Polyurethane bumpers have better abrasion resistance than neoprene bumpers. They won't become brittle and crack when exposed to ozone.

Threaded Bumpers
Mount these bumpers on a threaded stud. All are reinforced with a steel core 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. All of these bumpers can be used outdoors.
Bumpers with a medium and medium-soft rating offer a balance of cushioning and impact resistance. The softer the bumper, the more it cushions.
Bumpers with an extra-hard, hard, and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
Buna-N bumpers resist abrasion, oil, and grease.
Neoprene bumpers have good abrasion resistance.
Polyurethane bumpers have better abrasion resistance than neoprene bumpers. They won't become brittle and crack when exposed to ozone.
