M10 Thru-Hardened Split Lock Washer Zinc Plated

This washer is a coiled, hardened split circular washer designed to apply greater bolt tension per unit of applied torque and create more uniform torque control. While it resists loosening caused by vibration and corrosion just like a regular metric split lock washer, does it does so to a greater degree. For use with metric bolts and nuts of class 10 or higher. MLW10HA
