The Formwork Tie Nut is a critical fastening component engineered for modern concrete formwork systems, providing the necessary stability and structural integrity during the pouring and curing process. Manufactured from high-strength ductile iron casting (JIS FCD450), these nuts are specifically designed to withstand immense lateral pressure in a wide variety of applications, including wall, column, slab, pier cap, and tunnel formwork. Their robust construction ensures that formwork panels remain precisely aligned, preventing deformation and ensuring a high-quality concrete finish.
Designed for maximum efficiency on the job site, our tie nuts feature an ergonomic wing-like shape that allows for rapid hand-tightening and loosening without the need for specialized tools. Whether utilized in standard residential projects or demanding high-rise industrial structures, these components offer exceptional durability and reusability. With multiple sizes and customizable surface treatments such as zinc plating, our Formwork Tie Nuts are the professional choice for construction teams seeking a balance of safety, speed, and long-term reliability.
