Case-Hardened Carbon Steel Concrete Screw for Heavy-Duty Masonry and Brickwork Applications

Self-Tapping Thread Design:

• High-low thread geometry allows for easy driving and maximum debris removal, ensuring a tight, vibration-resistant fit without the need for additional expansion anchors.

High-Strength Case Hardening:

• The carbon steel core is case-hardened to achieve the perfect balance of surface hardness for thread cutting and core ductility to prevent snapping under high torque.

Dual Head Options:

• Available in Hex Washer Head for maximum driving power and Pan Head for a low-profile finish, catering to various aesthetic and structural requirements.

Premium Corrosion Resistance:

• Standard finishes include Blue or White Zinc plating, providing a robust barrier against moisture and atmospheric corrosion in indoor and sheltered outdoor environments.

Rapid Installation:

• Simply drill a pilot hole and drive the screw; this streamlined process increases site productivity by up to 50% compared to traditional mechanical anchors.

Carbon Steel (C1022A):

• The standard material for high-strength masonry applications, optimized for heat treatment.

Blue Zinc Plating:

• Provides aesthetic appeal and standard salt spray resistance (up to 72 hours).

White Zinc Plating:

• Offers a clean, professional look for visible installations.

Yellow Zinc / Galvanized:

• Available upon request for enhanced weather resistance.

HVAC Systems:

1. Securing brackets, ductwork, and unit supports directly to concrete walls.

Electrical Installations:

2. Mounting conduit straps, junction boxes, and lighting fixtures to masonry surfaces.

Exterior Framing:

3. Attaching wood or metal furring strips to brick or block foundations.

Storage Solutions:

4. Installing heavy-duty shelving and racking systems in warehouses and garages.

Safety Equipment:

5. Fastening handrails, guardrails, and safety barriers to concrete floors.

Window & Door Frames:

6. Direct fixing of frames into masonry openings for a secure, rigid fit.

Q: Do I need a specific drill bit for these screws?

1. A: Yes, concrete screws require a carbide-tipped masonry bit slightly smaller than the screw diameter. We can supply the corresponding bits with your order.

Q: Can these screws be reused?

2. A: We do not recommend re-using concrete screws in the same hole, as the threads cut into the masonry and the second installation will not achieve the same pull-out strength.

Q: Are Pyramid Concrete Screws suitable for coastal environments?

3. A: For coastal areas, we recommend our specialized high-corrosion resistant coatings like Ruspert or Dacromet.

Q: What is the minimum embedment depth?

4. A: For optimal performance, a minimum embedment of 25mm to 35mm is recommended depending on the base material density.

Q: Do you provide third-party inspection reports?

5. A: Yes, we welcome and accept inspections from SGS, BV, and TÜV to ensure compliance with your project specifications.
