FAQs
What is the maximum weight these anchors can hold?
These anchors are designed for light-duty applications. Specific weight ratings depend on the wall material's integrity and the type of screw used, but they are generally not recommended for heavy items. Always test the fixing with moderate pressure before attaching the final item.
Do I need a special tool to install these?
Yes, a wall anchor setting tool is required to properly expand the legs of the anchor behind the plasterboard, creating a secure hold. These are usually sold separately.
Can these anchors be used in solid brick walls?
No, these anchors are specifically designed for plasterboard and other hollow wall materials. They will not function correctly or provide adequate support in solid walls.
What size screw should I use with these anchors?
These are M4 anchors, so they are designed to be used with M4 screws. Ensure the screw length is appropriate for the thickness of your fixture and the wall cavity.
How do I remove a Diall Steel Button Hollow Wall Anchor?
These anchors are designed for permanent installation. Attempting to remove them after they have been set will likely damage the surrounding wall material.
What is the 'button head' feature?
The button head refers to the slightly rounded, flat head of the anchor that remains visible on the surface of the wall after installation. This provides a clean finish for screw insertion.
What is the fixture depth range?
These anchors are suitable for hollow wall materials where the fixture depth (the thickness of the material the anchor grips behind the wall) is between 6mm and 13mm.
Troubleshooting
Anchor does not expand or feel secure.
Ensure you are using the correct size drill bit for the anchor. Verify the wall material is indeed hollow and not solid. Confirm you are using a compatible setting tool and applying adequate force.
Setting tool struggles to engage or release.
Check that the anchor is fully seated in the hole and the tool is properly aligned with the anchor's shaft. Clean any debris from the setting tool and the anchor.
Hole is too large after drilling.
If the hole is too large, the anchor may not have sufficient material to grip. Consider using a larger anchor if available, or repair the hole and re-drill with the correct size bit.
Anchor spins in the hole before setting.
This can happen if the hole is slightly too large. Try to hold the anchor firmly in place while operating the setting tool, or consider using a different type of fixing if the material is too compromised.

Setup, Compatibility & Care
Setup:
- Drill a hole of the appropriate diameter for the M4 anchor in the plasterboard or hollow wall material.
- Insert the hollow wall anchor into the drilled hole. Ensure it sits flush with the wall surface.
- Using a wall anchor setting tool, engage the anchor. The tool will pull the anchor body forward, causing its legs to expand behind the wall.
- Once the legs are fully expanded and the anchor is secure, remove the setting tool. The button head will remain on the surface.
- Insert your screw through the fixture and into the anchor.
Compatibility:
- Material: Primarily designed for plasterboard, hollow core doors, and other thin, hollow panel materials.
- Not Compatible With: Solid walls (brick, concrete, solid wood).
- Screw Size: Typically requires M4 screws (not included).
- Fixture Depth: Best suited for wall cavities where the fixture depth is between 6mm and 13mm.
Care:
- These anchors are for single, permanent installation. Once set, they are not designed to be removed without damaging the wall.
- Ensure the area around the anchor remains clean and dry to prevent corrosion if exposed to moisture over extended periods (though typically used internally).
