    Threaded Shaft Collars

    Threaded shaft collars share the same performance and benefits of their round bore counterparts, while providing additional features. Threaded collars have higher axial holding power than round bore collars, while offering easier installation and adjustment than solid ring locking devices. A diverse list of acme, right hand, and left hand thread sizes and pitches are offered. Ruland double taps each threaded collar to ensure precise and burr-free threads to allow for easy installation and removal, proper fit, and extended shaft life. Threaded shaft collars are manufactured in 1215 lead-free steel with a black oxide finish and 303 stainless steel. Bore sizes range from 1/8" to 2-1/4" and 4mm to 30mm.
