These Forgefix Twist Nails are a unique twisted shank nail for attaching metalwork joists, hangers, straps etc. The twisted shank assists in absorbing movement that may occur in construction. They have a sheradised finish for corrosion resistance. This finish is a thermal diffusion process, in which Zinc powder is vaporised and diffuses to the surface of the Twist Nail to form a sacrificial corrosion protective Zinc/Iron alloy coating, thus dramatically increasing the nails’ durability.
The Twist Nail is the most popular construction nail used in fixing of joist hangers, restraining straps and Galvanised banding.
