With these Spax structural screws, you create exceptionally strong and reliable joints for timber framing, roof trusses, and carports. The full thread across the 120 mm length absorbs high tensile and compressive forces, ensuring a rigid and lasting bond between structural timber components. Its wide flange head delivers high clamping force and distributes pressure across the surface to prevent the head from pulling through. The engineered t-star plus T40 recess guarantees an exact bit fit for maximum torque transfer without slipping during deep fastening. Finished with a durable wirox coating, these steel screws provide significantly higher corrosion protection than standard zinc plating in covered outdoor and indoor structures.
