Products Description
Two-lug disc wing nut is the core load-bearing component of concrete formwork tie system, matched with 15mm and 17mm wall tie rods. Produced by integral hot forging process, it has dense internal structure without sand holes or air holes compared with ordinary cast nuts, featuring stable load capacity and crack resistance, which is a reliable fitting widely used for reinforcing wall and beam formwork. The wide disc base distributes force evenly to avoid formwork bulging and deformation, ensuring accurate concrete forming size. The two-lug design enables hand tightening without wrenches, convenient for assembly and disassembly. It can be reused many times to greatly cut overall material cost on construction sites.
Core Features
Integral hot forging, stable and strong load capacity
Constructed from solid Q235 steel through integral high-temperature forging, it boasts dense texture, great toughness and high tensile strength. Common cast nuts are brittle and prone to breakage, leading to formwork bulging, extra rework and schedule delays. Our forged nuts rarely crack and hold steady loads, safe for ordinary and high-risk wall construction.
01
Large disc design for even pressure and less rework
The widened disc provides larger contact area and uniform pressure distribution. It effectively prevents formwork bulging, deformation and slurry leakage caused by local pressure overload. It ensures flat and neat concrete surfaces and greatly reduces later repair and rework.
02
Tool-free hand installation with wide universal compatibility
Built with double lugs for quick hand assembly and disassembly without wrenches, improving formwork construction efficiency and saving labor costs. Standard thread fits common 15mm and 17mm wall tie rods. Easy stocking and replacement without size matching trouble.
03
Reusable structure for higher long-term cost performance
High-strength body is impact resistant and not easy to damage. The galvanized surface provides good anti-rust and anti-corrosion performance. The nut can be reused many times on construction sites, reducing replacement frequency and saving overall material costs for long-term projects.
