Timco Twin-Thread Woodscrews, PZ, Double Countersunk, Zinc, Size 8 x 3/4, 35-Pk

The Timco Twin-Thread Woodscrews are engineered for fast and secure installation in soft timber or masonry (with plastic plugs). Designed with a double countersunk head, these screws minimise the risk of head shear and ensure precise countersinking for a flush finish.

Constructed from C10-18 steel, these screws provide consistent quality and durability, featuring 60° twin-threads for faster insertion and enhanced pull-out resistance. The partially threaded design (on 1 1/4” and longer screws) ensures optimal grip without compromising structural integrity.

These woodscrews are surface-hardened to 750 HV, preventing torque shearing under load, while the core hardness of 450 HV improves ductility. The 25° sharp point and single lead ensure quick and smooth thread engagement, reducing splitting in softer materials.
