Diall Grey Multi-Purpose Screw & Wall Plug - Grey

You will need a 12mm masonry drill bit for optimal performance and a secure fit in solid substrates.

No, these Diall Multi-Purpose Wall Plugs are specifically designed for solid substrates like brick and concrete. For plasterboard or drywall, you should use specialized hollow wall anchors.

You should use a screw with a shank diameter between approximately 8mm and 10mm. Wood screws, chipboard screws, or self-tapping screws are generally suitable, ensuring the screw is long enough to fully engage the plug.

Drill the hole slightly deeper than the plug's length, ideally around 65-70mm, to allow space for any accumulated dust at the bottom of the hole.

Each pack of Diall Grey Multi-Purpose Screw & Wall Plugs (12mm x 60mm) contains 5 plugs.

Info needed: [The manufacturer does not provide a specific maximum load capacity for these plugs, as it heavily depends on the quality of the substrate, the type and length of the screw used, and the installation method. Always test the fixing in a non-critical area and consult an expert for heavy or critical applications.]

This usually indicates the drilled hole is too large or not cleaned properly. Ensure you used a 12mm masonry drill bit. Re-drill with a smaller bit if possible or move to a new spot. Clean the hole thoroughly to remove all dust.

Check if the screw diameter is appropriate (8-10mm for a 12mm plug) and if it's long enough to engage the full length of the plug. Also, ensure the substrate is solid and not crumbling, and that the hole was cleaned properly.

The hole may be drilled too large. Verify your drill bit is exactly 12mm. If the substrate is soft or crumbly, the plug may not get enough grip. Consider using a chemical anchor or a different type of fixing designed for softer materials if the substrate is compromised.

Double-check that the installation steps were followed precisely. Ensure the screw is fully engaged and tightened correctly. For critical loads, always use multiple fixing points and consult a professional, as the exact load capacity depends on the quality of the substrate and the screw used.
