RS PRO ZnPt Steel 1 Coil Spring Washer, M5


Use this spring coil washer from RS PRO when you need to prevent nuts from loosening due to vibration. The ends of the washer grab the nut as you tighten it, binding against it for a secure grip.

This washer is made of durable steel, so it's a long-lasting product. The zinc plating provides improved corrosion resistance, meaning it will stand up to harsh conditions without degrading or rusting.

The spring washer features a split that's designed to absorb the initial turning force of the screwdriver. This means you can tighten the nut fully without breaking the washer. It visibly closes under the weight of the bolt, so you know it's secure. Washers like this are the ideal choice for heavy-duty industrial environments that features strong vibration or corrosive chemicals.
