SPAX-RA Rafter Screws 7.5x210mm WIROX Cylinder Head are heavy-duty structural screws engineered for timber-to-timber connections in roof construction, rafter fixing, and structural timber framing. The large 7.5mm diameter and 210mm length deliver exceptional holding power in demanding structural applications.

Key Benefits

• Heavy-duty structural performance — 7.5mm diameter provides superior shear and withdrawal strength for structural timber connections.
• 210mm length — deep penetration for maximum holding power in thick timber members, rafters, and beams.
• WIROX coating — high-performance corrosion protection, significantly more durable than standard zinc plating, suitable for exposed structural applications.
• Cylinder head (Cyl/H) — low-profile head sits flush or slightly proud for a clean finish in structural connections.
• T-Star Plus T30 drive — exclusive to SPAX. Handles the high torque required for large diameter structural screws without cam-out.
• No pre-drilling required — on most structural timbers, saving time on site.
• Made in Germany — engineered to SPAX's exacting structural quality standards.

Ideal Applications

The SPAX-RA 7.5x210mm is ideal for rafter-to-wall plate connections, ridge beam fixing, structural timber framing, post and beam construction, and any application requiring a high-strength timber screw with deep penetration.
