Timco Twin-Thread Woodscrews, PZ, Double Countersunk, Zinc (6 x 25mm, 35pc)
Hardened zinc-plated twin-thread woodscrews (35pc) for fast, secure timber & masonry fixings.
The Timco Twin-Thread Woodscrews feature a double countersunk head that reduces the likelihood of head shear and ensures a clean, flush finish. These screws are surface-hardened up to 750 HV to prevent torque shearing under load, while the core hardness of 450 HV ensures improved ductility and durability. Made from high-quality C10-18 carbon steel, these woodscrews guarantee consistent performance and strength.
The 60° twin-thread design with a parallel shank allows for faster insertion and significantly greater pull-out resistance, making them ideal for soft timber applications or masonry when used with a plastic plug. The 25° sharp point and single lead start ensure quick and easy driving with improved thread acceptance in wood.
