Do you need to secure fastenings on machines that experience frequent shocks or vibration? This RS PRO shakeproof washer uses internal teeth to lock into place, keeping your nuts and bolts immobile and reducing maintenance and repair time on your equipment.
The washer's outer ring helps to absorb the impact of regular mechanical movement, further ensuring that your fixings stay secure. It's made of marine-grade 316 stainless steel, so it has very high resistance to corrosion. That means you can use this product in environments that feature saltwater or harsh chemicals.
This washer comes in a standard metric M5 size with an inside diameter of 5.3 mm so is compatible with a variety of nuts, bolts and screws. It's particularly useful in the transport industry, mechanical engineering or any application prone to heavy jolts or jostling.
