Galvanised Square‑Twist Nails 30 × 3.75 mm (1 kg pack)

These galvanised square‑twist nails are engineered for use in metal‑to‑timber connections, joist hangers, restraint straps, and other structural fixing scenarios where enhanced pull‑out resistance is required. The 30 mm length combined with a 3.75 mm shank diameter delivers reliable penetration and holding capacity in typical construction assemblies.

The twisted (square‑twist) shank design provides increased resistance to withdrawal compared to smooth round shank nails, making them especially suitable for fixings that must maintain integrity under vibration or load. The galvanised finish offers medium corrosion protection (Service Class 2) and meets the requirements of BS EN 14592:2008 for timber‑structure fasteners. Supplied in a 1 kg bag, this pack offers trade‑ready quantity for site use in general and heavy timber work.
