Timco twin-thread woodscrews (6x½”, zinc) for fast, strong fixings. Carbon steel with PZ drive. 200pc pack.
The Timco Twin-Thread Woodscrews are expertly designed for fast and secure installations. These traditional roundhead screws feature a single lead start, enabling quick and efficient fastening. Their partially threaded design (from 1¼ inch and above) ensures a strong grip with enhanced pull-out resistance, making them ideal for clamping flat surfaces or achieving a high-quality aesthetic finish.
Crafted from C10-18 carbon steel, these screws offer consistent strength and durability. The 60° twin-thread design paired with a parallel shank allows for faster insertion, reducing the effort required while maximising holding power. Additionally, the 25° sharp point and single lead ensure smooth thread engagement right from the start.
For added reliability, the screws are surface-hardened up to 750 HV, preventing torque shearing under heavy loads, while the 450 HV core hardness improves ductility. Combined with a zinc finish, they provide corrosion resistance for long-lasting performance in various applications.
