About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Inch 304 Stainless Steel and Nylon Plastic: Use with welded 304/304L and 316/316L stainless steel that meets ASTM A269 or ASTM A270, except ASME BPE: Use with welded or seamless 304/304L stainless steel that meets ASTM A269 or ASTM A270
Metric 304 Stainless Steel: Use with welded 304/304L and 316/316L stainless steel
Inch 316 Stainless Steel: Use with welded 304/304L and 316/316L stainless steel
Metric 316 Stainless Steel: Use with welded 316/316L stainless steel
Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.
Wing nut—These clamps tighten by hand, no tools required. Clamps with a spring closure can be installed with one hand, as the spring holds the clamp in place. Clamps with a safety wing nut have a wider wing nut base and a narrower clamp gate than our other wing nut clamps, so they stay latched even when bumped and knocked. This is useful in steam lines where accidentally releasing the clamp could cause injuries. They also have a leak-before-burst design, so rather than bursting dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.
Bolt—These clamps handle higher pressures than wing-nut and lever clamps for a stronger, more secure hold. Tighten them with a wrench. Clamps with double-bolt meet ASME design standards for pressure vessels.
Lever—These clamps are best when you need to frequently open and close this connection. They reduce the risk of damage caused by over- or under-tightening the connection because the lever compresses the gasket evenly every time. This also creates a flush connection that minimizes spots where bacteria could grow. A threadless design prevents improper tightening caused by damaged threads. Easy to adjust, these clamps don't require tools to use and can be used with multiple gasket materials.
Recessed nut—These clamps are tamper resistant to reduce the risk of product contamination. A hex socket adapter is required to loosen the nut. They have a leak-before-burst design, so rather than burst dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.
Clamps with a hole for a lockout help you comply with Hazard Analysis and Critical Control Point (HACCP) programs and Good Management Practices (GMP).
Clamps with a two-pin hinge require less clearance to open than other clamps. Use these for installation in tight spaces.
304 stainless steel clamps have very good corrosion resistance. 316 stainless steel clamps are more corrosion resistant than 304 stainless steel clamps. Nylon clamps are lightweight compared to stainless steel clamps.

The temperature rating of the fitting will vary depending on the gasket or O-ring material you choose. Buna-N is oil resistant. EPDM resists water and steam and works well in humid environments. Silicone withstands high temperatures. Fluoroelastomer stands up to fuel, oil, and acid condensates. PTFE withstands harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

Steel Clamping Hinged Pipe Collars with Wrench Flats

Sized to fit snugly around pipe, these collars have flats so you can turn the collar and your pipe using a standard wrench. This means you don't need to use a pipe wrench, which could scratch the surface of your pipe. These collars are also often used as a stop to support pipe as it passes through floors and walls. They’re also easy to machine, so you can drill and tap a hole through one of the flats to hang a sign. Swing them open to fit over your pipe and tighten them with a single screw—they’re faster to install than two-piece collars. All have captive screws, which won’t fall out of these collars even when fully unthreaded. Made of black-oxide steel, they have some corrosion resistance.

Hinged Shaft Collars

Offering the benefits of a two-piece collar in a one-piece design, these collars swing open for positioning then close anywhere on your shaft. Tighten the clamping screw to secure. The screw is captive so it won’t fall out, making these collars good for use in tight areas where you can’t hold the screw in place. Collars clamp evenly around your shaft to create a strong, mar-free hold.
Black-oxide steel collars have some corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.

Stackable Threaded-Rod-Mount Clamping Hangers


Mount these hangers on top of one another to organize multiple lines of pipe, tubing, and conduit at any angle. They include one or two clamping screws, which tighten around material and provide a more secure hold than loop hangers. Mount with threaded rod (not included), or some come with a stacking screw.
Hinged clamps have a triple-link design and a captive clamping screw to combine the flexibility of a two-piece clamp with the simplicity of a one-piece clamp. All are easy to assemble, reposition, and take apart.
End clamps are flat on one side and round on the other. The flat side has a mounting hole that can be used with 1/4"-20 threaded rod to mount or a 10-24 fastener to connect to the top of a stacking clamp. The round side provides a finished look. 303 stainless steel hangers have excellent corrosion resistance.

Low-Profile C-Clamps


With no handle or protruding screw, these clamps fit tight spaces. Open and close with a wrench, socket, or nutdriver.
Hinged clamps have a screw on the back rather than the top and they pivot open and closed to hold workpieces where vertical space is limited.
