Timco Classic Multi-Purpose Screws PZ, Double Countersunk, 4.0 x 80mm (200 Pack

The Timco Classic Multi-Purpose Screws PZ are engineered for versatility and performance across a range of materials, including hardwood, chipboard, MDF, plastic, and thin sheet metal. These screws feature a sharp 25° point and a special thread design, ensuring efficient insertion and exceptional holding power. The patented lubrication not only speeds up insertion but also enhances corrosion resistance, making them a durable choice for various applications.

These screws are partially threaded (70mm thread length for 80mm+ sizes), with all sizes up to 75mm being fully threaded. The double countersunk head minimises head shear risk and aids in countersinking, while the 40° deep single thread provides a secure fixing and high pull-out resistance. Additionally, surface hardening up to 750 HV prevents torque shearing under load, and the core hardness of 450 HV improves ductility. A single slash on screws 25mm+ reduces torque and the likelihood of timber splitting near edges.
