ZINC PLATED CARBON STEEL 5/8” BORE SHAFT COLLARS SETS - High-quality, fits well, and cheap. We provide you with the perfect balance between affordability and quality. If you are searching for parts that will last you for quite some time, our set of 4 bore shaft collars are manufactured to strict standards. Made from carbon steel, each bore shaft collar provides superior strength, and with the addition of zinc plating, it becomes corrosion-proof and more durable.

SCREW STYLE BORE SHAFT COLLARS WITH 5/8” BORE SIZE - Though the bore size is the most important fit consideration, you’ll also need to consider other components to ensure a perfect fit. Each of these bore shaft collars has an outer diameter of 1-1/8 inches, a 1/2 inch width (thickness), and a 5/16-18 inch clamp screw diameter.

SUITABLE FOR AUTOMOTIVE AND INDUSTRIAL USE - These are just two of the most common applications for these bore shaft collars. Common usage includes situating components in power steering assemblies, locating components on conveyor belt systems, and more. If you are unsure if these are the parts you need, remember that round bore shaft collars’ usual usage is as locators, spacers, stops, and bearing faces.
