Otter Washers, Zinc Clear, Box
For use with similarly gauged and finished nuts and bolts e.g. M6 galvanised flat washer for M6 galvanised nut and bolt of any length. Cold forged from hardened steel and hot dipped galvanised to prevent corrosion in moderate environments. Flat washers are designed to provide bearing face between the nut and/or bolt head and the material being fixed. Helps to prevent damage to the material being fixed and allows for greater tension to be applied to material being fixed.
For use with like-sized nuts and bolts. Can be used underneath the heads of nuts and bolts.
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 low level of corrosion protection.
