Timco Twin-Threaded Woodscrews PZ Countersunk Zinc 4 x 5/8 Box of 200

The TIMco Twin Thread Zinc Countersunk Woodscrew is designed for general use in softwood and various types of hardwood. It features a traditional twin-thread design with a single lead start for fast installation, and is suitable for soft timber applications or masonry with a plastic plug. The screw combines a 60° twin-thread with a parallel shank to promote faster insertion and greater pull-out resistance, while a sharp 25° point aids thread acceptance. Made from C10-18 steel and zinc plated, it provides robust hardness characteristics to maintain performance under load. A countersunk head design helps prevent head shear and facilitates flush seating. Partially threaded from 1 1/4” and above, this screw is built for consistent quality and reliable general-purpose use.
