FAQs
What type of material is the Fischer GB8 rawlplug for?
The Fischer GB8 rawlplug is specifically designed for use in porous concrete and aerated concrete (also known as aircrete).
Can I use these rawlplugs in regular dense concrete?
No, these rawlplugs are not designed for dense or solid concrete. Their unique rib structure requires the softer nature of porous or aerated concrete to function correctly.
What is the benefit of the spiral-shaped outer ribs?
The spiral ribs cut into the soft building material, creating a positive fit that ensures the best pressure distribution and high load-bearing capacity.
Do I need any special tools to install them?
No, the GB8 rawlplugs are designed for simple hammer-in installation, saving you the need for specialized tools.
Can these be used for outdoor applications?
Yes, they can be used safely outdoors when combined with approved fischer safety screws in A4 grade, which provides corrosion resistance.
What is the weight of the pack?
A pack of 25 Fischer GB8 Porous Concrete Rawlplugs weighs approximately 0.0440924524 pounds.
Are these approved for safety-relevant attachments?
Yes, the Fischer GB gas concrete dowel is a special bolt approved by building authorities for safety-relevant attachments in aerated concrete.
Troubleshooting
Rawlplug does not grip securely.
Ensure the hole diameter and depth are correct for the GB8 plug. Verify that the substrate is indeed porous concrete or aerated concrete, as the plug's design is specific to these materials. Check for any debris in the pre-drilled hole.
Difficulty inserting the rawlplug.
Confirm the pre-drilled hole size matches the rawlplug diameter. Ensure the hole is clean and free of obstructions. Apply firm, direct hammer blows to seat the plug correctly.
Screw does not tighten properly.
The rawlplug may not be fully seated, or the hole may be slightly oversized. Try removing the rawlplug and re-inserting it, ensuring it's fully flush. If the hole is too large, consider using a larger size plug if available or filling and re-drilling.
Pros and Cons
Pros
- Quick and easy hammer-in installation saves time.
- High load-bearing capacity due to optimized design.
- Specifically designed for secure use in porous and aerated concrete.
- Durable construction from high-quality polyamide.
- Approved for safety-critical applications.
Cons
- Not suitable for dense concrete or non-porous materials.
- Requires pre-drilling for installation.
- Effectiveness depends on the quality of the porous substrate.
- Specific screw types (A4 safety screws) are needed for exterior applications.
Setup, Compatibility & Care
Setup:
- Drill Hole: Drill a hole of the appropriate diameter into the porous concrete or aerated concrete.
- Insert Rawlplug: Gently tap the Fischer GB8 rawlplug into the pre-drilled hole using a hammer until it is flush with the surface.
- Insert Screw: Insert the appropriate screw (e.g., fischer safety screw) through the fixture and into the rawlplug.
- Tighten Screw: Tighten the screw firmly to secure the fixture.
Compatibility:
- Substrates: Primarily designed for use in porous concrete and aerated concrete. Not recommended for dense concrete, brick, or other solid materials.
- Screws: Compatible with standard metric thread screws. For exterior applications, fischer A4 safety screws are recommended for optimal performance and corrosion resistance.
Care:
These rawlplugs are designed for single-use installation and do not require regular maintenance. Ensure the surrounding material remains sound. Store unused plugs in a dry place to prevent degradation.
