  • Made in the USA by Coastal Machine Works. We strive to deliver high quality and precise collars. Every collar has its edges and holes deburred and its corresponding inside diameter bore engraved on its front face for easy identification.
  • Made from 303 stainless steel, these shaft collars have excellent corrosion resistance and are ideal for wet environments or when corrosive chemicals are present.
  • The two-piece design makes installation simple. The split collar can be disassembled and reassembled anywhere along the shaft without needing to remove other components or having access to the ends of the shaft.
  • Strong, even clamping pressure around the shaft is created using the two included 1/4-28 x 5/8” stainless steel socket head screws. Compared to set screw style collars, the two-piece design has significantly higher clamping force and will not mar the shaft/pipe.

What we Focus on to Deliver High Quality Products

Deburred and Chamfered Edges

Extra care is taken to deburr the edges of the counter bore and the exit of the tapped hole. This reduces the risk of injury from sharp burrs and improves the overall look of the collar.

Precise Dimensions

Quality control and inspection steps during the manufacturing process ensure that every collar meets or exceeds the required tight dimensional tolerances.

Engraved Sizes

An engraving operation adds both the bore size and the country of origin to every collar making size identification easy. This is convenient when working with a variety of different sizes.

Common Shaft Collar Uses

Shaft collars are a very common mechanical components with a wide range of applications. They are generally used to control the position or movement of components on shafts. From industrial uses such as locating sprockets, bearings, and gearboxes in a fixed positions to more everyday applications such as holding plates on a barbell or keeping an umbrella locked to a patio table. There is nearly an unlimited number of use cases. The pictures below illustrate some of the places I've used shaft collars in a more industrial setting.
