Otter Washers Spring, Zinc Clear, Handy Pack
For use with similarly gauged and finished nuts and bolts e.g. M6 galvanised spring washer for M6 galvanised nut and bolt of any length. Cold forged from spring steel and hot dipped galvanised to prevent corrosion in moderate environments. Spring washers are designed to provide additional tension between the nut and the material being fastened to aid in preventing the nut from working lose due to low levels of vibration or minor timber shrinkage.
For use with like-sized nuts and bolts. Aids in preventing nut working loose.
Hot dipped galvanised for use in moderate external environments. Hot dipped galvanising is a sacrificial coating that helps to prevent corrosion. Electroplated zinc for aesthetics and use in internal dry conditions. Provides only a very low level of corrosion protection.
