Timco Twin-Thread Woodscrews - PZ Double Countersunk, Zinc (10x80mm, 140pcs)

The Timco Twin-Thread Woodscrews are designed for efficient and secure fastening in timber and masonry applications. These high-quality screws feature a double countersunk head, reducing the likelihood of head shear and ensuring a flush finish every time.

Crafted from C10-18 carbon steel, these screws are surface hardened up to 750 HV to prevent torque shearing under load, while a core hardness of up to 450 HV ensures improved ductility. The 60° twin-thread design with a parallel shank offers faster insertion and greater pull-out resistance compared to standard woodscrews, making them ideal for soft timber or masonry (when used with a plastic plug).

A 25° sharp point and single lead start provide a fast drive start and improved thread acceptance, saving you time and effort. The screws are partially threaded (from 1 1/4” and above) for optimal holding power.

Key Features:

• Double countersunk head reduces head shear
