The DIN 127 metric lock washer is a mechanical fastener designed to prevent loosening or rotation of a 12mm screw under external vibrations or load. With an inner diameter of 12.2mm, outer diameter of 20.3mm, and a thickness of 2.5mm, it acts as a compression spring, creating tension to securely hold the screw in place. Additionally, the zinc yellow finish provides offers more resistance to corrosion than normal zinc plating thanks to the chromate coating that provides an extra layer of protection.
