Product Information
Full details
These Diall Hex Frame Fixings are designed for professionals and DIY enthusiasts needing a robust solution for securely installing window and door frames in solid materials. Their primary benefit is providing a strong, reliable, and clean finish for uPVC, timber, and metal frames. A minor consideration is their specific application in solid materials, meaning they are not intended for hollow walls.

FAQs
What is the correct drill bit size for these fixings?
For the 8mm diameter Diall Hex Frame Fixing, you should typically use an 8mm drill bit for most solid materials. Always consult the specific requirements for your chosen substrate material for best results.
Can these fixings be used in aerated concrete blocks?
These fixings are designed for solid materials. While they might offer some hold in dense aerated concrete, they are optimized for denser materials like concrete, dense blockwork, brick, and stone. For very light or hollow blocks, a specialized anchor may be more appropriate.
What does the 'winged design' do?
The wings on the fixing increase the friction between the fixing and the wall material, providing a much stronger grip and preventing the fixing from spinning or pulling out easily. They also help to prevent rotation during the tightening process.
How many fixings are recommended per frame?
The number of fixings required depends on the size and type of frame, as well as local building regulations. For standard window and door frames, using at least 4-6 fixings (one in each corner and potentially mid-span) is common practice. Always distribute them evenly.
Can these be used for external doors?
Yes, these fixings are suitable for external doors as they are designed for solid materials and offer a secure, weather-resistant installation when used correctly in compatible substrates.
Are these fixings re-usable?
These are designed as permanent fixings and are not intended for repeated removal and reinstallation. Once tightened into a material, attempting to remove and re-use them may compromise their holding power.
Troubleshooting
Fixing does not tighten fully
Ensure the pilot hole is drilled to the correct depth and diameter. Check that the substrate material is solid and not crumbling. If the hole is too large or the material is weak, a larger fixing or alternative anchoring method may be required.
Frame is not held securely
Verify that all fixings have been used and tightened sufficiently. Ensure the correct drill bit size was used for the substrate. Re-drill holes if they appear too large or worn.
Difficulty inserting the fixing
Confirm the pilot hole is clear of debris. Ensure the drill bit used was the correct size for the fixing. For very hard materials, a pilot hole might need to be started with a smaller bit before reaming to the final size.
Pros and Cons

- Provides a very secure and stable fixing for frames.
- Winged design enhances grip and reduces the chance of pull-out.
- Suitable for a wide range of common solid building materials.
- Contributes to a neat and professional final installation.
- Durable construction for long-lasting performance.
Cons
- Not suitable for use in hollow wall applications.
- Requires appropriate drilling and tooling for installation.
- Pack quantity may be insufficient for very large projects.
Setup, Compatibility & Care
Setup:
- Drilling: Select the correct drill bit size for the fixing diameter (8mm) and the substrate material (e.g., masonry bit for concrete or brick). Drill holes to the appropriate depth, ensuring they are clean and free of debris.
- Insertion: Position the window or door frame in the opening. Insert the Diall Hex Frame Fixings through the frame and into the pre-drilled holes in the solid material.
- Tightening: Use a socket wrench or spanner to tighten the hex head of the fixing. Gradually tighten each fixing alternately to ensure even pressure on the frame and prevent distortion. Tighten until the frame is secure and does not move.
Compatibility:
- Frame Materials: uPVC, timber, metal.
- Substrate Materials: Solid concrete, blockwork, brickwork, stone.
- Not compatible with: Hollow walls, plasterboard, or materials that cannot provide adequate support for the fixing's length and diameter.
Care:
These fixings are designed for permanent installation and typically do not require ongoing care. Ensure the surrounding area is kept clean to prevent ingress of moisture that could potentially affect the longevity of the fixing or surrounding materials over extended periods. In harsh environments, occasional inspection of the installation is recommended.
