Description
A tray of traditional twin-thread woodscrew with single lead start for a fast installation. Mainly used in soft timber applications or masonry with a plastic plug. NOTE: Partially threaded from 1 1/4″.
The double countersunk head reduces the likelihood of head shear and assists completion of countersinking. Made from C10-18 steel to ensure consistent quality, it has 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. 25? sharp point and single lead for a fast start and improved thread acceptance.
