Timco Twin-Thread Woodscrews, PZ, 10 x 1 3/4in, Zinc (200pcs)

The Timco Twin-Thread Woodscrews provide a fast and reliable solution for woodworking and general construction applications. These premium-quality screws are manufactured from C10-18 carbon steel for consistent performance and durability. The double countersunk head design reduces the risk of head shear while helping to complete the countersinking process efficiently.

Key features include 60° twin-threads with a parallel shank for faster insertion and superior pull-out resistance. The screws are partially threaded (from 1 1/4” and above) to enhance grip strength, making them ideal for soft timber applications or masonry when used with plastic plugs. The surface is hardened up to 750 HV to prevent torque shearing under load, while the core hardness of up to 450 HV improves ductility.

With a 25° sharp point and single lead start, these screws ensure smooth and quick thread engagement, reducing installation time. The zinc finish offers corrosion resistance, making them suitable for both interior and exterior use.
