Premium zinc-plated twin-thread woodscrews for fast installation & strong holding power in timber/masonry. 30pc pack.
The Timco Twin-Thread Woodscrews offer superior holding power and fast installation thanks to their innovative twin-thread design with single lead start. Made from high-quality C10-18 carbon steel, these screws are surface hardened to 750 HV for maximum resistance to torque shearing under load, while maintaining a 450 HV core hardness for improved ductility.
