FAQs
What size drill bit do I need for this fixing?
You will need an 8mm drill bit to create the correct size hole for this fixing.
Can I use these fixings on plasterboard?
No, these hammer fixings are designed for solid materials like brick, concrete, and stone only. They are not suitable for hollow walls or plasterboard.
How do I know if the fixing is secure?
The fixing is secure when the countersunk head is flush with the surface of the material and the fixing does not move when slight pressure is applied.
What is the maximum load capacity?
The load capacity depends heavily on the base material. Always refer to manufacturer guidelines or perform a test fixing for critical applications.
Do I need any special tools besides a hammer and drill?
No, typically only a hammer, a drill with an 8mm masonry bit, and possibly a dust brush or vacuum to clean the hole are required.
Can I remove and re-use this fixing?
These are designed as permanent fixings. While it may be possible to extract them, they are not intended for removal and re-use, as the nylon sleeve can be damaged.
Troubleshooting
Fixing does not go in easily.
Ensure the correct 8mm drill bit was used and the hole is clean. For very hard materials like dense concrete, a pilot hole with a smaller bit might be necessary first, or a more powerful hammer may be required.
Fixing feels loose after installation.
The hole may be too large, or the material might not be solid enough. Ensure the correct drill bit size is used and that the base material is appropriate for this type of fixing.
The screw part is difficult to turn after hammering.
These fixings are designed to be hammered in, and the screw head is primarily for the initial drive. If it feels seized, it indicates the fixing is already anchored. Gentle tapping on the screw head with a hammer might help seat it fully, but significant rotation is not intended after the hammer-in stage.
Pros and Cons
Pros
- Extremely fast installation time due to hammer-in design.
- Secure anchoring in solid building materials.
- No need for a separate screwdriver during installation.
- Cost-effective for multiple fixings.
- Versatile for various light to medium-duty applications in solid substrates.
Cons
- Not suitable for hollow walls or plasterboard.
- Requires a drill and appropriate drill bit for hole preparation.
- Limited adjustability once hammered in.
- May require significant force to hammer in harder materials.
- Correct drill bit size is crucial for optimal performance.
Setup, Compatibility & Care
Setup:
- Drill an 8mm diameter hole into the solid wall, brick, concrete, or stone. Ensure the hole depth is sufficient for the 80mm fixing.
- Clear any dust from the drilled hole.
- Insert the Diall PZ Countersunk Hammer Fixing into the hole.
- Use a hammer to drive the fixing fully into the hole until the countersunk head is flush with the surface.
Compatibility:
- Suitable Materials: Solid brick, concrete, stone, dense blockwork.
- Not Suitable For: Hollow walls, plasterboard, lightweight blocks, aerated concrete.
Care:
These fixings are designed for single use and are not intended for removal and re-insertion. Once installed in a suitable material, they provide a permanent fixing. No specific care is required after installation, as they are load-bearing components within the structure.
