Master Distributor of Quality Shaft Collars and Couplings 

Who We Are

Since 1981, Collars and Couplings have focused on selling high-quality shaft collars and couplings at competitive prices. We currently only sell to distributors, primarily in the power transmission, industrial supply, and fastener markets.

Anyone can say they are all about quality, service, and performance but we live it every day. With a highly experienced team (some of whom have 20+ years in the business) and a wide range of value-added services, it's clear we are focused on supporting our customers' success.

What We Do

Offering products such as solid shaft collars & couplings in steel, stainless, and aluminum. As well as supplying packaged steel chrome balls & packaged quantities of hose clamps, our network of qualified distributors can help you find what you need. 

Our in-stock inventory features solid set screw, split, double split, and threaded collars in inch and metric, standard and heavy profiles. Not to mention, keyed and keyless couplings which also come in solid set screw, split, double split, and machinable, are also available in metric and inch sizes.

Core Values

Customer Service tops our list of core values. It may seem old-fashioned, but we believe in answering the phone not relying on an automated attendant and a series of clicks. When you call Collars and Couplings, you can be assured someone will pick up the phone and personally answer your questions. Our customers have come to rely on us because of our "hands-on approach".
