TIMCO Twin-Thread Woodscrews – PZ – Double Countersunk – Zinc – 10 x 2 1/2

The Twin-Thread Woodscrews – PZ – Double Countersunk – Zinc are traditional twin-thread screws designed for fast and efficient installation. Featuring a single lead start, they provide quick penetration and strong holding power, making them ideal for soft timber applications and masonry when used with a plastic plug.

The double countersunk head reduces the risk of head shear and allows for clean and flush countersinking. Made from high-quality C10-18 steel, these screws ensure consistent strength and durability. The 60° twin-threads and parallel shank enhance faster insertion and superior pull-out resistance, while the surface-hardened core prevents torque shearing under load for long-lasting performance.

Partially threaded from 1 1/4” and above, these screws optimize clamping force for structural integrity. The 25° sharp point and single lead provide a fast start and smooth thread engagement, ensuring precise fixing with minimal effort.
