Square twist nails are extra-strong fasteners specifically designed for fixing joist hangers and restraint straps. The square twisted shank provides exceptional grip in timber, ensuring that critical structural connections remain secure under load. Unlike standard round wire nails, the twist creates a mechanical lock that resists both pull-out and shear forces — exactly what's needed for structural metalwork fixings.
Galvanised for long-lasting corrosion protection, these nails are coated to withstand exposure to damp conditions. The galvanised finish creates a tough, protective layer that won't chip or flake when driven through metal connectors. Whether used internally or externally, they provide the dependable corrosion resistance required for structural applications.
Manufactured to exacting standards, our square twist nails meet the rigorous demands of modern construction. When you're fixing a joist hanger or restraint strap, you need a nail you can trust — and that's exactly what we deliver.

The galvanised square twist nail is purpose-built for structural metalwork fixings. Here's where they're essential.
The primary use for square twist nails — fixing joist hangers to timber. The extra-strong square shank provides the shear strength needed for load-bearing floor connections.
The specified nail for fixing lateral restraint straps in masonry and timber frame construction. The twist ensures the strap stays locked tight against the structure.
The extra strength of square twist nails makes them ideal for truss clips, framing anchors, and other stamped metal connectors where a standard nail simply won't do.
The galvanised coating provides reliable protection against moisture, making these nails suitable for environments where dampness is a concern — including ground floor joist applications.
Many building control specifications call for square twist nails when fixing joist hangers and straps. Using the correct nail ensures your work passes inspection first time.
Any application where a metal bracket, plate, or strap needs fixing to timber — the square twist nail provides the strength and grip that standard round nails can't match.
Getting the right length, gauge and finish is crucial for performance. Here's what you need to know.
