Advanced M6-M20 Concrete Screw Anchors: The Modern Fastening Solution
Our Concrete Screw Anchors represent the latest evolution in mechanical anchoring. By cutting a thread directly into the base material, these self-tapping concrete bolts provide a high-strength connection without the radial expansion forces associated with wedge anchors. This makes them ideal for use in cracked concrete and applications close to edges.
Whether you need a Hex Head Concrete Screw for heavy racking or a Countersunk Screw for flush-mount window frames, our hardened steel fasteners ensure a fast and secure installation every time.
- Fast Installation: Simply drill, clean, and drive. No torque wrench or setting tool needed.
- Fully Removable: Ideal for temporary structures, formwork, or racking that may need relocation.
- No Expansion Stress: Allows for significantly smaller edge distances and spacing between anchors.
- High Vibration Resistance: The continuous thread engagement provides superior grip under dynamic loads.
| Screw Size | Drill Bit Dia. | Min. Depth | Max. Fixture Thickness |
|---|---|---|---|
| M6 | 6 mm | 40 mm | 10 – 50 mm |
| M8 | 8 mm | 60 mm | 15 – 80 mm |
| M10 | 10 mm | 75 mm | 20 – 100 mm |
| M12 | 12 mm | 90 mm | 25 – 120 mm |
| M16-M20 | 16/20 mm | 120+ mm | Heavy Duty Only |
- Drill: Drill a hole using a bit the same diameter as the concrete screw’s nominal size (e.g., use an 8mm bit for an M8 screw).
- Clean: Blow out all dust and debris. This is critical to prevent the screw from seizing during installation.
- Drive: Use an impact wrench or socket to drive the screw through the fixture into the concrete until the head is seated.
- Warehouse Racking: Quick and easy installation of pallet racks.
- Temporary Structures: Site fencing, scaffolding, and formwork.
- Public Infrastructure: Stadium seating, railings, and acoustic barriers.
- Glazing & Doors: Securing frames directly into masonry or concrete.
