This RS PRO shakeproof washer is an ideal solution for securing fastenings on machines that will be subject to frequent vibration or shocks. Thanks to its internal teeth that lock it into place, it'll keep your nuts and bolts immobile, minimising maintenance and repair time on your equipment.
It's highly resistant to corrosion as it's made from marine-grade 316 stainless steel. That makes it a good choice for use with harsh chemicals or saltwater. The washer's outer ring helps absorb the impact of regular mechanical movement, so you can be sure that your fixings will stay firmly in place.
This standard metric M12-size washer has an inside diameter of 13 mm, so it's compatible with a range of screws, nuts and bolts. You'll commonly find it used for applications that involve jostling or heavy jolts in the transport or mechanical engineering industries.
