SPAX rakennusruuvit T40 lautakanta ruostumaton teräs A2 8 mm x 220 mm, 50 kpl 0257000802205

These SPAX wood construction screws combine a T-STAR plus T40 drive, a washer head, and stainless steel A2 material for reliable fastening in outdoor timber structures. The 8 mm diameter and 220 mm length suit pergolas, carports, and other load-bearing wood connections.

Highlights

• Washer head with MULTI-head design for a clean finish and reduced sinking
• T-STAR plus T40 drive for secure bit engagement and high torque transfer
• Stainless steel A2 provides corrosion resistance for outdoor use
• 4CUT point reduces splitting and allows screwing without pre-drilling in many woods
• Partial thread with SPAX wave profile for strong clamping

In daily use

The 4CUT point displaces wood fibres and minimises the need for pilot holes, while the T-STAR plus drive prevents cam-out even under high torque. The washer head distributes pressure and sits flush on the surface. Stainless steel A2 withstands weather exposure, making these screws suitable for permanent outdoor constructions.
