ForgeFix General Purpose Twin Thread Screws 3 1/2" x 12 Zinc Plated Box 100

The Forgefix General Purpose Pozi Compatible Screws with Countersunk heads provide a versatile solution for a wide range of fixing applications. Designed for durability, these screws are zinc plated, ensuring increased wear resistance and preventing oxidation of the protected metal. This zinc coating forms a protective barrier that not only prolongs the finish but also acts as a sacrificial anode if the barrier becomes damaged. The zinc oxide formed is a fine white dust that is significantly less harmful than iron oxide, aiding in the preservation of the substrate's integrity.

Construction and Design

These screws boast a countersunk head, which allows them to sink flush with the substrate, providing a smooth surface finish. The unique design includes twin threads that not only facilitate an easier start when driving but also enhance holding power. Additionally, the screws are equipped with an extra deep insert bit recess, allowing for quicker and easier insertion, ultimately leading to a firmer positive drive.

The Pozidriv design sets these screws apart from the traditional Phillips cross-head screws. Unlike Phillips screws, which have a rounded corner and only two points of contact, the Pozidriv features four additional contact points, significantly reducing the risk of cam-out when used with the appropriate tooling. This design allows for greater torque application, making them suitable for various applications that require a reliable fastening solution.

Applications

These general-purpose screws are ideal for use in a variety of ironmongery, electrical, and plumbing applications. Their versatility extends to multiple substrates, including softwoods, hardwoods, chipboards, and fibreboards. The ability to use various screw cover caps with these screws further enhances their application range, making them a popular choice among professionals and DIY enthusiasts alike.
