FAQs
What is the main benefit of the Hammerfix N Green?
Its main benefit is the speed and ease of installation due to its pre-fitted nature, making assembly significantly quicker than traditional methods in solid building materials.
What does 'Green' signify in the product name?
The 'Green' designation indicates that the product is manufactured using at least 50% renewable raw materials that do not compete with food cultivation areas, highlighting its environmental consideration.
Can I use the Hammerfix N Green for exterior projects?
No, the Hammerfix N Green is designed and specified for internal building materials only. It is not suitable for exterior applications or in damp environments.
What types of walls is this product suitable for?
It is suitable for solid internal building materials such as concrete, solid sand-lime brick, building brick, natural stone, solid lightweight concrete, and aerated concrete.
What is the maximum thickness of the material that can be fixed?
The maximum panel thickness (e.g., timber) that can be fastened with this specific model (8 x 80/40 S) is 4 cm.
Do I need a special tool to install it?
You will need a hammer to initially seat the sleeve and drive the nail screw, and a PZ3 screwdriver bit for turning the nail screw.
How do I know if the fixing is secure?
The nail screw should be driven in until its head is flush with the surface of the material being fixed. A secure fixing will not pull out under the intended load.
Troubleshooting
Fixing does not feel secure after installation.
Ensure the correct drill bit size (8 mm) was used and the hole was drilled to the appropriate depth. Verify the base material is suitable (solid brick, concrete, etc.). Check if the nail screw was driven in completely.
Nail screw is difficult to drive in.
Confirm the hole is clear of debris. Ensure you are using a PZ3 screwdriver and a hammer for driving the nail screw. The base material might be exceptionally hard, requiring more force.
Fixing sleeve does not expand properly.
This can occur if the hole is too large or the base material is too soft. Ensure the correct drill bit size is used for the specified material.
Pros and Cons

Setup, Compatibility & Care
Setup:
- Drill Hole: Drill a hole with an 8 mm diameter into the base material. Ensure the minimum drill hole depth is met (9.5 cm for the 80 mm length). For materials like aerated concrete, specific drilling instructions for that material should be followed.
- Insert Sleeve: Push the green fixing sleeve into the drilled hole until it is flush with the surface.
- Position Fixture: Place the object to be fastened (e.g., timber batten) over the sleeve.
- Drive Nail Screw: Using a hammer and a PZ3 screwdriver, drive the nail screw through the fixture and into the sleeve. Continue until the head is flush with the surface.
Compatibility:
- Suitable Materials: Concrete, solid sand-lime brick, building brick, natural stone, solid brick from lightweight concrete, and aerated concrete.
- Not Suitable For: Hollow materials, plasterboard, or external applications.
- Timber Thickness: Maximum panel thickness of 4 cm.
Care:
- The Hammerfix N Green is a one-time-use fixing. Once installed, it cannot be removed and re-used.
- Ensure the installation environment is dry.
- Store unused fixings in their original packaging in a dry place.
