Lock washers are used for creating tight assemblies with ordinary fasteners. Raptor Supplies offers a wide range of lock washers from brands like Unistrut, Vulcan-Hart, Midwest Acorn Nut, Fabory, Super-Strut, Metric Blue, Woodhead, Foreverbolt, Cooper B-Line, Disc-Lock and Armor Coat. These lock washers grab adjoining materials for preventing loosening due to vibration.
Flat washers are suitable for increasing the surface area and distributing the applied force when tightening the fastener. They can be used on the fastener's bolt & nut sides, or used as spacers where using a bolt may not be suitable.
Lock washers create tension during tightening to prevent the loosening of nuts. They are generally used on the fastener's nut side for applications involving vibrations.
Split Lock, Tooth Lock, Diamond-Coated Lock, Spring Lock and Wedge Lock type lock washers have vibration resistance in ascending or increasing order.
