Left Hand Threaded Collar, Bore M4x0.7, Steel, OD 16mm MPN:MTCL-4-0.7-F-LH

Ruland clamp style shaft collars do not mar the shaft, are infinitely adjustable, and have superior holding power when compared to set screw collars. This one-piece left hand threaded shaft collar has an M4 x 0.7 bore, 16mm OD, and 9mm width. Threads are double tapped to ensure a burr-free finish which extends shaft life and allows for easier installation. Threaded collars allow for higher axial holding power than traditional round bore types. Left hand threading is commonly used when right hand threading is not feasible or for safety to prevent the unintended removal of critical components. Tightly controlled face to bore perpendicularity is maintained (TIR of < 0.05mm) which is critical when the collar is used as a load bearing face, mechanical stop, or for component alignment. The work surface is identified by two grooves on the face allowing the user to easily identify which side is precision faced. This collar is stamped with the Ruland name and bore size for ease of identification. It is manufactured from 1215 lead-free steel to a fine burr-free finish with Ruland's proprietary black oxide formulation which creates a fine glossy appearance and increases holding power and corrosion resistance. Hardware tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
