Our one piece clamping collars allow for greater clamping force than set screw shaft collars. They promise not to mar the shaft. One piece clamp-on shaft collars simply slide onto the shaft and are secured with a screw. They clamp evenly around the shaft therefore providing excellent holding power. Made of carbon steel with a Black-Oxide finish to offer mild corrosion resistance. Our shaft collars are available in several different styles to meet you or your customer's needs.
