Timco Twin-Thread Woodscrews, PZ, Zinc Plated, 10x1½

The Timco Twin-Thread Woodscrews are a high-quality fastening solution designed for soft timber applications and masonry (when used with plastic plugs). These partially threaded screws feature a traditional twin-thread design with single lead start for quick and efficient installation.

Made from C10-18 carbon steel, these screws offer consistent quality and durability. The surface is hardened up to 750 HV to prevent torque shearing under load, while the core maintains a hardness of up to 450 HV for improved ductility. The 60° twin-threads with parallel shank provide faster insertion and greater pull-out resistance compared to standard screws.

Key features include:

• Double countersunk head - reduces likelihood of head shear and assists in countersinking
• 25° sharp point - ensures fast start and improved thread acceptance
• Partially threaded from 1¼
