Product Information
Full details
This Rawlplug Frame Screw is designed for professionals and DIYers seeking a fast, user-friendly, and strong fixing solution, particularly for applications involving frames, ceilings, and lightweight steel. Its key benefit is the elimination of additional plugs, saving time and effort. However, it requires a pre-drilled 6mm hole in many common substrates, which is a crucial step for optimal performance. The screw is made of hardened, electro-zinc coated steel and offers high load capacities with minimal substrate stress due to its non-expanding nature.

FAQs
Do I need to use a wall plug with this screw?
No, this Rawlplug frame screw is designed to be used without additional plugs in most suitable materials when a 6mm pilot hole is drilled.
What is the maximum load capacity of this screw?
The load capacity varies significantly depending on the substrate material. Consult the official Rawlplug technical data sheets for specific load values for concrete, brick, stone, etc.
Can I use this screw in plasterboard?
This screw is not designed for direct use in plasterboard. If fixing into plasterboard, you must ensure there is a solid backing material (like timber or metal stud) behind it, and drill a 6mm hole into both the plasterboard and the backing.
What is the correct drill bit size?
A 6mm diameter drill bit is required for pre-drilling into most suitable substrates.
What does 'expansion-free fixing' mean?
It means the screw does not create outward pressure on the material as it is installed, unlike traditional anchors. This reduces the risk of cracking or damaging brittle substrates.
Can this screw be removed and reused?
Yes, the screw is designed to be easily removed for temporary works. However, repeated removal and re-insertion may compromise the holding power in the substrate.
What material is the screw made from?
The screw is made of hardened steel and is electro-zinc coated for protection.
Troubleshooting
Screw does not tighten or spins freely.
Ensure the pilot hole is 6mm and drilled to the correct depth. Verify the substrate is suitable. If in aerated concrete or timber, check for excessive porosity or damage that prevents the screw from self-tapping effectively.
Screw head breaks during tightening.
You may have exceeded the recommended torque limit (30Nm). Ensure you are using the correct driver bit and applying steady, controlled pressure. Back out the screw slightly and re-tighten gently.
Difficulty inserting the screw.
Check that the pilot hole is clean and free of debris. Ensure you are using the correct 6mm drill bit size for the material. For direct fixing into timber or aerated concrete, ensure the material is firm enough to self-tap.
Corrosion observed on the screw.
The electro-zinc coating provides moderate corrosion resistance. For prolonged exposure to moisture or aggressive environments, consider alternative fixings or protective coatings.
Pros and Cons
Pros
- User-friendly and time-efficient installation process.
- High load capacity from a relatively small hole.
- Reduced stress on the substrate due to non-expanding design.
- Suitable for a variety of common building materials.
- Clean, flush finish with countersunk head design.
- Easy removal for temporary installations.
Cons
- Requires pre-drilling a 6mm hole in most dense materials.
- Not suitable for direct use in very soft materials without pre-drilling.
- Electro-zinc coating may not be sufficient for highly corrosive environments.
- Specific torque limit (30Nm) must be observed for optimal performance.
- Primarily designed for frame-type fixings, may not be ideal for all general-purpose applications.
Setup, Compatibility & Care
Setup:
- Determine Substrate: Identify the material you are fixing into (e.g., concrete, brick, timber, aerated concrete).
- Drill Pilot Hole: For most dense materials like concrete, full brick, and stone, drill a 6mm diameter hole to the required depth.
- Insert Screw: Place the frame screw into the pre-drilled hole or directly into aerated concrete or timber (no pre-drilling needed for these).
- Tighten: Using an appropriate driver bit, tighten the screw until it is flush with the surface and secure. Do not overtighten. The recommended maximum torque is 30Nm.
Compatibility:
- Suitable For: Pre-drilled 6mm holes in concrete, full brick, hollow brick, stone, structural clay tile. Direct fixing (no pre-drilling) in aerated concrete and timber.
- Not Recommended For: Very soft materials like plasterboard without appropriate backing, or highly corrosive environments without additional protection.
Care:
- Cleaning: Wipe clean with a dry or slightly damp cloth. Avoid abrasive cleaners.
- Storage: Store in a dry place to prevent premature corrosion of the zinc coating.
- Inspection: Periodically check fixings, especially in applications subject to vibration or load changes.
