Threaded Bore Precision Clamping Shaft Collar

A threaded-bore clamping shaft collar locks onto a threaded rod or lead screw to provide a stop or locating shoulder, with a split ring and clamp screw. Dayton Superior is known mainly for concrete construction accessories such as rebar and anchors rather than precision shaft collars, so this listing may name the wrong maker. It is used as a positioning stop on machines and conveyors.
