Formwork Tie Nuts are precision-engineered fastening components essential for maintaining the structural integrity of concrete formwork systems. Manufactured from high-strength ductile iron casting (JIS FCD450), these tie nuts provide a secure connection for various formwork applications, including wall, column, slab, pier cap, tunnel, and climbing formwork. Their robust design is specifically engineered to withstand significant lateral pressure during the concrete pouring process, ensuring perfectly aligned and stable structures.
Designed for maximum efficiency on the construction site, our tie nuts feature an ergonomic wing-like shape that allows for rapid manual tightening and loosening without the need for specialized tools. Available in a wide range of sizes (from D12 to D20) and surface treatments including yellow and silver galvanization, these components offer exceptional durability and corrosion resistance. Whether for standard residential projects or complex high-rise industrial structures, these tie nuts ensure a secure, adjustable, and reusable fastening solution.
