Walraven Hex Head Concrete Screw

This hex-head concrete screw is engineered for demanding anchoring applications in both cracked and non-cracked concrete, as well as hollow-core slab structures. It features a robust steel zinc-plated construction and a hexagon head design with a pre-pressed washer to ensure secure fixation and strong bearing on the fixture. The specially designed tip and thread minimise risk of spalling around the anchor hole, and the option of multiple embedment depths provides flexibility for installation into varying concrete thicknesses. With fire-resistance up to R120 and full approvals for use in fire-protection and heavy duty anchor-systems, it is well suited for structural, mechanical, or safety-critical fixings.

• Very high load capacity: Enables anchoring of heavy structural and mechanical loads with confidence.
• Hexagon head with pre-pressed washer: Ensures strong bearing under fixtures and facilitates secure torque application.
• Up to three anchoring depths: Enhances design flexibility and simplifies stock-holding by covering multiple embedment requirements.
• Reduced edge and anchor spacing: Allows closer placement to boundaries and between anchors, improving layout efficiency.
• Unique tip and thread geometry: Minimises risk of spalling and damage during both installation and service life.
• Fire-resistant up to R30–R120: Suitable for installations where fire performance is required, supporting compliance with safety regulations.
• Approved for sprinkler-system concrete installations: Meets VdS CEA 4001 certification for use with fire-protection systems in concrete elements.
• Versatile substrate compatibility: Suitable for cracked concrete, non-cracked concrete and precast hollow-core slabs, broadening application across building types.
