Remarks to collars from steel:
The black oxide on the clamping collars is formulated as part of the total performance of the product. It enhances the holding ability of the collar, it efficiently reduces slipping on the shaft, has anti-stick-slip characteristics and helps to keep the torque rating of the screw within its designed parameters. The oxide layer also provides corrosion protection.
