Timco 4 x 5/8 Twin-Thread Woodscrews, Zinc, 200pc

The Timco Twin-Thread Woodscrews are designed for fast and secure installations in soft timber or masonry (with plastic plugs). These high-quality carbon steel screws feature a traditional twin-thread design with a single lead start, ensuring quicker insertion and superior pull-out resistance.

Key benefits include a double countersunk head to reduce head shear risk and assist with countersinking, plus surface hardening (up to 750 HV) to prevent torque shearing under load. The 60° twin threads and parallel shank enhance performance, while the 25° sharp point ensures a fast start and improved thread acceptance.
