Galvanised Square Twist Nails

The galvanised square twist nail is the hardened, twist-shank fastener designed for high-withdrawal resistance in hardwood and dense timber applications. At the DIY Hardware Store, our square twist nails are available for the garden construction, decking, fencing, and hardwood joinery applications where standard round wire nails don't provide sufficient grip.

The square twist profile creates a helical groove in the surrounding timber as the nail is driven, and the compressed and displaced timber fibres grip around the twist profile with significantly greater resistance to withdrawal than a plain shank. This makes twist nails the preferred fastener for hardwood decking boards, dense timbers that grip smooth shanks poorly, and any fixing that will be subject to repeated loading or impact. Galvanised finish ensures long-term outdoor durability.
