TIMco Masonry Screws - Countersunk - Silver - 6.0 X 40mm

No, these screws are specifically designed for masonry applications like concrete, brick, and stone. They are not suitable for plasterboard.

For the 6.0 x 40mm screws, a 6mm drill bit is generally recommended for solid masonry. Always refer to specific guidelines or test in a small area if unsure.

The zinc coating provides a degree of corrosion resistance, making them suitable for some outdoor applications. However, for prolonged exposure to weather or damp conditions, a stainless steel alternative might be more appropriate.

It means these screws are designed to be screwed directly into a pre-drilled hole in masonry without the need for a separate plastic wall plug or anchor.

You will need a standard drill or impact driver, and importantly, a TX25 driver bit to engage with the screw head recess.

Yes, their all-steel construction is non-flammable and compliant with BS 7671 (18th Edition) standards for fire safety, making them suitable for applications like wiring installations where fire performance is critical.

The serrated V-threads and high-low thread geometry are engineered to efficiently cut into masonry materials, providing a stronger grip and easier insertion compared to conventional screw threads.

Ensure the pilot hole is the correct size (typically 6mm) and depth. Check if the masonry material is solid and suitable for this type of screw. If drilling into softer materials or hollow sections, consider alternative fixing methods.

Verify that you are using a TX25 bit and that it is in good condition. Ensure the bit is fully inserted into the screw head recess. Avoid excessive force which can damage the recess.

Ensure the pilot hole is drilled straight and to an adequate depth. For a perfectly flush finish, slight over-drilling or widening the top of the pilot hole might be necessary, but do not compromise the screw's grip.

This is rare with correct usage but can occur if excessive force is applied or if the screw encounters an obstruction. Ensure the correct pilot hole size is used and avoid over-tightening.
