RS PRO Bright Zinc Plated Steel Locking Washers, M4, DIN 7980

Coil spring washers provide a more consistent and secure grip compared to flat washers as their single coil, spring build is designed to absorb a higher level of shock and vibration providing a constant tension, allowing a greater degree of load bearing.

Suitable for operating in harsh environments due to the Bright Zinc Plating with a higher level of temperature resistance compared to plain washers and featuring a strong resistance to corrosion.

Built to comply with DIN 7980 these hard wearing washers are ideal for a wide range of environments and for use with applications and machinery where a standard washer will not cope with the vibration level, or you require a washer with a higher load bearing level.
