Timco Twin-Threaded Woodscrews PZ, Double Countersunk, Zinc, 12x4 (100-Pack)
Fast, durable Timco twin-thread woodscrews (12x4, PZ) for timber & masonry. Zinc-coated, countersunk & Pozi-drive. 100 pieces.
The Timco Twin-Threaded Woodscrews offer a reliable fastening solution for soft timber and masonry (when used with plastic plugs). These partially threaded screws feature a double countersunk head, designed to reduce the likelihood of head shear and ensure smooth countersinking.
Crafted from C10-18 carbon steel, these screws provide consistent quality. The 60° twin-thread design with a parallel shank ensures faster insertion and greater pull-out resistance. The screws are surface-hardened up to 750 HV, preventing torque shearing under heavy load, while maintaining a core hardness of up to 450 HV for improved ductility.
The 25° sharp point and single lead allow for a quick start and better thread acceptance, making installation both efficient and secure.
