Bimetal Hex Flange Concrete Screws
Product Details
Fasto Bi-metal concrete screws are engineered for high-load structural mounting in the most demanding environments. By fusing a corrosion-resistant stainless steel body with a hardened cutting thread, these anchors deliver exceptional clamping force without the need for expansion plugs, ensuring long-term integrity in both indoor and outdoor applications.
Advanced Material Fusion : The dual-material design combines the superior corrosion resistance of SUS 304/316 with the extreme hardness of an AISI 420 cutting tip, allowing for effortless penetration into high-strength concrete.
High Torque Hex Flange : The integrated washer head distributes clamping pressure evenly across the fixture surface, while the hex drive ensures maximum torque transfer and prevents head stripping during heavy-duty installation.
Expansion-Free Anchoring : Unlike traditional anchors, our screws create a mechanical interlock by cutting directly into the substrate. This eliminates expansion stress, permitting installation closer to concrete edges and tighter spacing.
Optimized Thread Geometry : Featuring a specialized high-low or coarse thread design, these screws maximize pull-out resistance and anti-vibration performance in cracked concrete, solid brick, and natural stone.
Industrial Grade Coating : Available in a Ruspert or plain finish, providing a verified multi-layer barrier against atmospheric corrosion, making them ideal for HVAC systems, maritime projects, and industrial machinery.

Applications
Our Bi-Metal concrete screw anchors are engineered for high-load structural mounting in cracked and uncracked concrete. Specifically optimized for environments requiring high corrosion resistance and vibration-proof fastening, they provide a reliable, expansion-free solution for heavy-duty installations.
HVAC & Mechanical Systems : Ideal for securing heavy air conditioning units, industrial ventilation ductwork, and outdoor motor brackets to solid concrete walls or pads.
Structural Steel Mounting : Designed for fastening steel base plates, storage racking systems, and machinery frameworks directly to concrete flooring with high shear strength.
Coastal & Marine Engineering : The SUS 304/316 body provides superior protection in saline or high-moisture environments, perfect for pier railings, boardwalks, and seaside infrastructure.
Public Utilities & Safety : Reliable attachment for outdoor handrails, stadium seating, and highway acoustic barriers where long-term structural integrity and anti-loosening are critical.
Commercial Industrial Fit-outs : Optimized for rapid mounting of fire protection pipes, cable trays, and heavy-duty shelving in warehouses and chemical processing plants.
