TIMco Masonry Screw - Silver - 6.0 x 80mm

For most light-duty applications in concrete, brick, or stone, a pilot hole is recommended for optimal performance and to prevent material cracking. The exact size of the pilot hole may vary depending on the density of the masonry. For softer materials, it may sometimes be possible to drive without a pilot hole.

You will need a masonry drill bit for creating the pilot hole. For driving the screw, you will need a TX25 driver bit, typically found on impact drivers or drills.

The zinc-coated finish provides some corrosion protection, making them suitable for protected outdoor use. For prolonged or harsh outdoor exposure, corrosion may occur over time.

No, these are designed specifically for light-duty applications. For heavier loads, you would need to consider masonry anchors or heavier-duty screws.

This compliance means the screws are tested and certified as non-flammable and suitable for use in electrical installations where fire safety is a critical concern, such as fixing conduits or cable management systems.

If the screws are already installed, cleaning is generally not recommended or necessary. If you have loose screws that are dirty, wipe them with a dry or slightly damp cloth. Avoid harsh chemicals that could damage the zinc coating.

Cam-out refers to the tendency of a driver bit to slip out of the screw head recess during tightening. The TX25 drive recess is designed to minimize this, providing a more secure engagement and reducing wear on both the bit and the screw.

The pilot hole may be too large. Try using a screw of the same diameter but slightly longer, or re-drill and use a larger diameter screw if necessary. Ensure you are not attempting to over-tighten.

Ensure you are using a good quality TX25 driver bit that is fully engaged in the recess. Apply firm, consistent pressure directly behind the screw head. Check if the pilot hole is too small, causing excess resistance.

A pilot hole is likely required. Ensure the pilot hole diameter is correct for the screw (consult TIMco guidelines or test). Use a hammer drill setting for harder materials if necessary.

This usually indicates over-tightening or trying to drive the screw into an obstruction. Back the screw out if possible and re-attempt with less force, ensuring the pilot hole is adequate.
