FAQs

What is the primary advantage of using these concrete screws?

The main advantage is that they eliminate the need for separate wall plugs, simplifying the installation process when fixing items directly to masonry.

What type of material can these screws be used in?

These screws are designed for use in solid masonry materials like concrete, brick, and dense blockwork.

Do I need to use a wall plug with these screws?

No, the design of these concrete screws is specifically to eliminate the need for separate wall plugs when fixing into masonry.

What is the required drill bit size for the pilot hole?

Typically, a 5mm drill bit is recommended for a 6mm diameter screw in concrete or brick. Always refer to specific guidance for your masonry type.

Can these screws be used for outdoor applications?

They are made of steel and suitable for general use. For heavily exposed external environments, consider screws with enhanced corrosion protection.

How deep should I drill the pilot hole?

The pilot hole should be at least the length of the screw (60mm) plus some extra depth to allow for debris clearance. Ensure it's deep enough for the screw to achieve full thread engagement.

What is the pack quantity?

This product is supplied in a pack of 10 screws.

Troubleshooting

Screw does not grip or turns freely in the hole.

The pilot hole may be too large or not deep enough. Redrill the hole with the correct size bit and ensure it is clean and sufficiently deep. Verify you are drilling into solid masonry.

Screw head snaps off during tightening.

You may be over-tightening the screw, or the pilot hole may be obstructed. Ensure the correct torque is applied and the hole is clear. If the head has snapped, you may need to drill it out and start again.

Difficulty driving the screw into the masonry.

The pilot hole may be too small, or the masonry may be exceptionally hard. Ensure the correct drill bit size is used. A hammer drill is recommended for very hard materials.

Pros and Cons

Pros

  • Simplifies installation by removing the need for wall plugs.
  • Provides a strong and durable fixing directly into masonry.
  • Steel construction ensures longevity and resistance to corrosion.
  • Pan head design offers good surface contact and holding power.

Cons

  • Only suitable for use in masonry substrates (brick, concrete).
  • Requires a pre-drilled pilot hole of the correct size.
  • Not suitable for lightweight or hollow wall materials.
  • Incorrect installation depth can compromise holding power.
  • Limited to the specified 6mm diameter and 60mm length.

Setup, Compatibility & Care

Setup:

  1. Determine the appropriate pilot hole size for your masonry type (refer to manufacturer recommendations or test). Typically, a 5mm drill bit is suitable for a 6mm screw in concrete or brick.
  2. Drill a hole of the required depth (at least 60mm plus clearance for debris) into the masonry. Ensure the hole is clean and free of dust.
  3. Place the frame or item to be fixed against the masonry, aligning it with the pre-drilled holes.
  4. Insert the Diall T40 screw through the frame and into the pilot hole in the masonry.
  5. Use a suitable drill driver or wrench to drive the screw in until the frame is securely tightened against the masonry. Avoid over-tightening.

Compatibility:

  • Suitable for: Solid masonry materials such as concrete, brick, and dense blockwork.
  • Not suitable for: Plasterboard, hollow blockwork, timber, or other non-masonry materials.

Care:

  • These screws are made of steel and are designed for internal or protected external use. For exposed external applications, consider screws with enhanced corrosion resistance.
  • Store screws in a dry place to prevent premature rust.
  • Clean any debris from pilot holes before insertion for optimal performance.
