Forgefix Self-Tapping Screw - Pozi - Countersunk - 1.1/2in x 8 - White
Forgefix Pozidriv Self-Tapping Screws offer exceptional performance in various applications. With ...Forgefix Pozidriv Self-Tapping Screws offer exceptional performance in various applications. With a length of 1.1/2 inches and a box containing 200 screws, these high-quality screws feature countersunk heads for a smooth, flush finish. They are zinc plated for excellent corrosion resistance and longevity. These self-tapping screws create their own threads in pre-drilled pilot holes in sheet and solid materials, ensuring quick and efficient installation. Their single-thread design enhances pull-out resistance for a secure fit. Ideal for DIY, ironmongery, engineering, electrical, and plumbing tasks, these screws provide versatility and reliability. The zinc coating prevents oxidation and acts as a sacrificial anode, forming a protective barrier. Unlike iron oxide, zinc oxide is a fine white dust that does not compromise surface integrity. The Pozidriv design has four additional contact points compared to Phillips screws, reducing cam-out and allowing for greater torque application with the correct tooling. Pozidriv screws are identifiable by a line embossed at a 45° angle on the screw head. Choose Forgefix Self-Tapping Pozidriv Screws for a blend of strength, durability, and ease of use.
