ForgeFix General Purpose Twin Thread Screws 1 1/4" x 8 Zinc Plated Box 200

The Forgefix General Purpose Pozi Compatible Screws with Countersunk heads are an essential addition to any toolkit, designed for versatility and durability. These screws are zinc plated, providing enhanced protection against corrosion and ensuring a longer-lasting finish. They are particularly popular for a wide range of applications, including ironmongery, electrical work, and plumbing.

Application and Use

These screws are suitable for fixing into a variety of materials, including:

- Softwoods

- Hardwoods

- Chipboards

- Fibreboards

Their design allows for use with various screw cover caps, offering a neat appearance in finished projects. The twin thread design promotes an easy start when driving the screw in, making installation quicker and more efficient. The screws are also equipped with a special wax coating that further increases the speed and ease of insertion.

Corrosion Resistance

The zinc coatings on these screws serve a dual purpose: they create a barrier that prevents oxidation of the protected metal, and they act as a sacrificial anode in the event that the barrier becomes damaged. This means that if any scratches or wear occur on the screw, the zinc will corrode instead of the underlying metal, maintaining the integrity of the screw. In contrast to iron oxide, zinc oxide forms a fine white dust that does not compromise the surface integrity of the substrate. If this layer remains intact, it can provide additional protection against further oxidation.

Pozidriv <a class='cat-link' href='https://bigshopper.co.uk/brand/head/'>Head</a> Design

The screws feature a Pozidriv head, which closely resembles the classic Phillips cross-head but possesses several distinct advantages. The Pozidriv design includes four additional points of contact, offering greater torque without the risk of camming out when used with the appropriate tooling. This allows for a more secure and reliable fixing. The Pozidriv screws can be easily identified by a line embossed at 45 degrees to the slots on the screw head, which signifies its design.

The countersunk head is specifically designed to sit flush with substrates, providing a smooth finish that enhances the overall aesthetic of any project.
