Hot Dip Galvanised Locknuts offer corrosion resistance up to 1,000 hours salt spray, making these Locknuts suitable for outdoor use in extreme environments such as electricity pylons. They are designed to free spin onto a galvanised bolt, negating the need to re-thread the bolt.

Designed to be used with or without a standard nut, these Locknuts offer excellent anti-vibration locking and are ideal for applications where frequent load changes would tend to loosen conventional nuts. In addition they do not require a torque wrench to fit, simply turn the nut to finger-tight and then tighten 1/3 to 1/2 a turn.

After proper tightening, the hex faces become slightly concave, making visual examination a reliable inspection method. This can give a considerable saving on in-place costs compared to other locking nut systems.

Material - Austempered Carbon Steel.
