Lock Washers

Split lock washers provide greater bolt tensioning as far as tighter assemblies are concerned. Besides, they secure against loosening which results from vibration. Split lock washers are used with a standard washer to offer a uniform bearing surface. General use is what these washers are largely meant for.
