SEMS Machine Screws
SEMS screws come pre-assembled with a free spinning lock washer that is held in place permanently by the major diameter of the screws thread. This eliminates the need of hand assembling washers onto the screw saving you time, resources, and the potential for lost or dropped washers in the production line. SEMS screws are used in applications where loosening is a concern.
