Countersunk Tight-Grip External-Tooth Lock Washers

To keep 90° countersunk screws from loosening in vibration applications, the teeth on these washers bite further into the screw head and joint than standard external-tooth lock washers for a more secure hold. Made of zinc-plated steel, these washers resist corrosion in wet environments. All meet DIN dimensional standards.
