Product Information
Full details
The Diall PZ Countersunk Hammer Fixing (8mm x 60mm, Pack of 50) is designed for professionals and DIY enthusiasts needing quick, secure fixings in solid building materials. Its primary benefit is the time-saving hammer-in installation with a pre-fitted screw, ensuring a reliable anchor. A potential caveat is that it's intended for solid materials and may not be suitable for hollow or plasterboard applications. This product offers an efficient solution for attaching timber constructions and similar items to walls.

FAQs
What is the correct drill bit size for this fixing?
You will need an 8mm drill bit for the pre-drilled hole.
Can I use these fixings in plasterboard?
No, these fixings are designed for solid materials like brick, concrete, and stone. They are not suitable for hollow walls or plasterboard.
How deep should I drill the hole?
The hole depth should be sufficient to accommodate the full length of the nylon sleeve, typically slightly deeper than the sleeve's length to ensure proper expansion.
Do I need to screw the screw in myself?
No, the screw comes pre-fitted into the nylon sleeve, allowing for immediate installation.
What does 'PZ Countersunk' mean?
PZ refers to Pozidriv, a type of screw head drive. Countersunk means the head is designed to sit flush with the surface when fully installed.
What kind of loads can these fixings support?
These fixings are suitable for moderate loads in solid materials. Always ensure the material's integrity and consider the shear and pull-out strength required for your specific application.
Troubleshooting
Fixing does not go in easily
Ensure the pre-drilled hole is the correct diameter (8mm) and depth. Check for obstructions in the hole. Do not force the fixing; re-drill if necessary.
Fixing feels loose after installation
The building material might be too soft, porous, or not solid enough. Verify you are using the fixing in compatible materials (solid brick, concrete, stone). For very soft materials, a different type of anchor may be required.
Screw head is damaged during hammering
Use a hammer with a flat face and strike the screw head squarely. Avoid glancing blows. If the head is significantly damaged, the fixing may need to be removed and replaced.
