Left-Hand Threaded Shaft Collars
Shaft collars with left-hand threaded bore have increased axial holding power when compared to equivalently sized round bore shaft collars. Threads are double tapped for a fine, burr free finish. Left-hand threading is used for safety to prevent the collar from coming loose in rotating applications as well as to prevent the uninteded removal of components. Available from #8 - 32 TPI to 2-1/4 in - 12 TPI and from M4 x 0.7 to M30 x 3.5.
