JCP Fixings Concrete Screws - 7.5 x 100mm - Gold

These screws are designed for securely fastening items to solid concrete surfaces, suitable for a wide range of applications from home DIY projects to professional installations.

Yes, these screws feature a T30 drive and come with a T30 drive bit included, which is what you will need to install them.

The durable materials suggest suitability for various conditions, but long-term outdoor exposure may depend on environmental factors. Keeping them clean and dry when not in use is recommended.

The white cover cap is a decorative element that provides a clean and finished look to the installation after the screw has been secured.

These screws are specifically optimized for concrete. While they might offer some hold in other dense masonry, their performance is best guaranteed in solid concrete.

For optimal performance, it is recommended to use a pilot hole size that matches the shank diameter of the screw, typically specified by the manufacturer or determined through testing for your specific concrete density.

The screws measure 7.5 x 100mm.

Ensure the pilot hole is correctly sized and cleared of debris. Verify the screw is being driven into solid concrete, not a void or crack. Check for any damage to the screw threads.

Confirm you are using a T30 bit. Ensure the bit is fully seated in the screw head and that both the bit and the screw head are clean and free of damage.

Use a torque-limiting setting on your drill/driver if available. Ensure the drill is set to the correct rotation (clockwise for tightening). Do not force the screw if resistance is too high; check pilot hole and concrete integrity.
