The Forgefix Pozidriv Self-Tapping Screws are expertly designed with a zinc plating that enhances their resistance to corrosion, making them a durable choice for a variety of applications. Featuring a flat under-head surface, the Pan Head design allows these screws to lay flat on all types of sheet materials, reducing the risk of deformation. They tap their own thread in pre-drilled pilot holes in sheet metal, ensuring a secure fit every time. Each screw is single-threaded to effectively resist pull-out, making them ideal for a range of DIY projects, ironmongery, engineering, electrical, and plumbing tasks. The zinc coating serves a dual purpose: it not only prevents oxidation of the underlying metal for a longer-lasting finish but also acts as a protective barrier. If this barrier is compromised, the zinc functions as a sacrificial anode, further safeguarding the metal beneath. Unlike iron oxide, which can damage the surface integrity of metals, zinc oxide forms a fine white dust that can actually protect the substrate if left undisturbed, similar to the oxide layers that protect aluminum and stainless steel. Distinguishable from traditional Phillips screws, the Pozidriv design features four additional contact points and lacks the rounded corners of Phillips drives. This unique design minimizes the risk of cam-out when paired with the correct tooling, allowing for superior torque application. The Pozidriv screws can easily be identified by a distinct line embossed in the screw head, positioned at a 45-degree angle to the driver slots.
