  • These two-piece aluminum split shaft collars have an inside diameter of 1.125 inches, an outside diameter of 1.875 inches and a thickness of 0.50 inches. This pack includes 2 split collars and their corresponding screws.
  • 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 2024 aluminum, these shaft collars are lightweight and have good corrosion resistance
  • 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" black-oxide alloy 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.


I started Coastal Shaft Collars in 2021 as a side hustle to my mechanical engineering job that involved designing equipment for the food processing industry. We used thousands of collars a year and a few things bugged me. The quality of the foreign collars we were using always seemed to be subpar and the price was high for what we were getting. I set out to make collars onshore using high-quality stainless steel and spending the extra time to make sure I’m delivering a first-rate product. Every edge and hole is deburred to reduce/eliminate the risk of cuts. The country of origin and bore size is engraved to make identification easy. Finally, every collar is rinsed, washed and dried to remove any oil residue from the machining process. My hope is that you enjoy the fit and finish of my collars as much as I enjoy making them.

Maybe this is the way they are all made but I thought it would close around a pipe completely. Not so. I can see that if it closed all the way you may not be able to get it tight enough but then seller could just state that it closes with a gap.. This would make a huge difference to many buyers who didn't know that. Plus, negative feedback would go away as I can see these are a quality piece of machining and would do what they are supposed to do. For my project, they won't work not closing all the way. .

I got the 1". After taking it out from the package I almost made the mistake of hitting the roof when I first saw the ID not being perfectly round. I took my digital caliper out and it was only 22mm cause it "was fully closed" which is why it does not look perfectly round. Loosened the screews until I got 1" ID and it was perfect circyle.Will be buying more for a project and supporting USA products. So keep in mind the size you purchase is the ID its rated at which will give you a perfect circle.

I'm using these to secure my racing harness on my roll cage. I picked these because they're aluminum, therefore lighter than the stainless steel versions. Every gram counts!

Fast shipping, good quality and nice fit and finish. The reviewer above who says they are not round bla bla is unaware that split collars will have a small gap between them when tight. The 1.25in I received are nice and round with what looks like a .115 gap designed in. It worked great and wont hesitate to order more.
