Mainly used in soft timber applications or masonry with a
plastic plug. NOTE: Partially threaded.

Features:
• Double countersunk head reduces the likelihood of head shear and assists completion of countersinking
• Partially threaded from 1 ¹⁄₄ ” and above
• Zinc plating 3-5 microns
• Made from C10-18 steel to ensure consistent quality
• 60° twin-threads with parallel shank for faster insertion and greater pull-out resistance
• Surface hardened up to 750 HV to prevent torque shearing under load and a core hardness of up to 450 HV for improved ductility
