Timco Twin-Thread Woodscrews, PZ, Double Countersunk, Zinc (6 x 25mm, 35pc)

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.

Key Features:

• Double countersunk head for reduced head shear
• 60° twin-thread design for faster driving and grip
• Surface hardened (750 HV) for torque resistance
• 25° sharp point for fast driving start
• PZ drive (Pozi recess) for secure screwdriver fit

Ideal for joinery, carpentry, and DIY projects, these screws provide a strong, long-lasting fixing solution.
