Timco Classic 3.0 x 25 Multi Purpose Yellow CSK Screw (Box of 200)

• Double countersunk reduces the likelihood of head shear and assists completion of countersinking • Patented lubrication, designed to enhance screw insertion time and provides greater resistance to corrosion • 40° deep single thread to provide a secure fixing with high 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 • All sizes up to and including 75mm are fully threaded and lengths 80mm and above all have 70mm thread length • Single slash on 25mm+ to reduce torque and the likelihood of the timber splitting when the screw is inserted close to the edge
