Timco Twin Thread Woodscrews PZ, Double Countersunk, Zinc, 4 x 1/2, 200pk
Timco PZ double countersunk woodscrews, ideal for timber & masonry. Zinc-plated, 4x1/2, pack of 200. Fast installation with twin-thread.
The Timco Twin Thread Woodscrews offer fast and reliable fixing for a variety of applications. Designed with a single lead start, these screws ensure quick installation, making them ideal for soft timber or masonry with a plastic plug.
The double countersunk head minimises the risk of head shear and aids in proper countersinking. Manufactured from C10-18 carbon steel, they provide consistent quality and durability. With 60° twin-threads and a parallel shank, these woodscrews allow for faster insertion while ensuring greater pull-out resistance.
The surface hardening up to 750 HV prevents torque shearing under load, while the core hardness of up to 450 HV improves ductility. The 25° sharp point and single lead facilitate a smooth start and superior thread acceptance, reducing splitting in timber.
