• Surface hardened up to 750 HV to prevent torque shearing under load and a core hardness of up to 450 HV for improved ductility
• Single slash on 25mm+ to reduce torque and the likelihood of the timber splitting when the screw is inserted close to the edge
Features
- Pan head for improved clamping
- Fully threaded up to 75mm, thereafter partially threaded
- 40° deep single thread to provide a secure fixing with high pull-out resistance
