JCP Fixings Concrete Screws - 7.5 x 40mm - White

These JCP Fixings Concrete Screws are specifically designed for secure fastening in concrete, solid brick, and other hard masonry materials.

A T30 drive bit is required for installing these screws. This is often included with the screws or readily available.

No, these screws are engineered for hard materials like concrete. They are not suitable for use in wood, drywall, or softer substrates.

The dimensions of these concrete screws are 7.5mm in diameter and 40mm in length.

The white cover cap is provided to offer a neat and clean aesthetic finish after the screw has been installed, hiding the screw head.

You will need a standard drill or impact driver equipped with a T30 drive bit. A masonry drill bit is required to create the pilot hole in the concrete.

While made from durable materials, prolonged exposure to harsh weather without protection might affect their appearance over time. For critical outdoor structural applications, professional advice is recommended.

Ensure the pilot hole is drilled correctly to the recommended diameter and depth for the screw size. Check that the drill bit is suitable for masonry and is not worn. Verify you are using a T30 drive bit properly seated in your drill/driver.

Reduce driving speed and torque. Ensure the T30 bit is fully engaged with the screw head and is not damaged. Use a new, undamaged bit if necessary.

The pilot hole may be too large or the concrete may be compromised. Remove the screw and attempt installation in a slightly different location or re-evaluate the concrete's integrity. Ensure the screw is fully seated.

Ensure the cover cap is the correct size for the screw and is being pressed firmly onto a clean screw head. Sometimes minor debris can impede fit.
