Timco Twin-Threaded Woodscrews, PZ, Double Countersunk, Zinc (6 x 1 3/4 - 200pc

Timco Twin-Threaded Woodscrews feature a traditional twin-thread design with a single lead start for fast and efficient installation. They are primarily used in soft timber applications or masonry when paired with a plastic plug. These screws are partially threaded, offering a balance between grip and ease of installation.

The double countersunk head reduces the risk of head shear and ensures a flush finish. Suitable for applications where both strength and speed are essential, these woodscrews are crafted from C10-18 carbon steel, guaranteeing consistent quality and durability. The 60° twin-threads and parallel shank ensure faster insertion and superior pull-out resistance, making them ideal for heavy-duty use.

To enhance performance, these screws are surface-hardened up to 750 HV to prevent shearing under load, while the core hardness of up to 450 HV improves ductility. The 25° sharp point and single lead facilitate quick starts and better thread acceptance, ensuring a smooth and secure fastening process.

These woodscrews come in a zinc finish for corrosion resistance and include a PZ2 (Pozi) recess type for compatibility with standard PZ bits.
