SPECIFICATIONS
A cross-recessed, pan head machine screw with a free spinning, conical captive lock washer. The conical washer SEMS offers a controlled tension with minimal torque while providing a higher retained clamp load than possible with other styles of lock washers. The SEMS can withstand a high tension load and still have the conical washer maintain its spring action. This style of SEMS is preferred when fastening more fragile materials since its load is spread to the outermost diameter of the lock washer
