Specification Brand : Coastal Shaft Collars BulletPoint1 : These two-piece aluminum split shaft collars have an inside diameter of 1.00 inches, an outside diameter of 1.75 inches and a thickness of 0.50 inches. This pack includes 4 split collars and their corresponding screws. BulletPoint2 : 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. BulletPoint3 : Made from 2024 aluminum, these shaft collars are lightweight and have good corrosion resistance BulletPoint4 : 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. BulletPoint5 : 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.

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.
