TIE ROD , WING NUT & FLANGE NUT

 A Tie Rod is a key formwork accessory used to hold and secure formwork panels during concrete pouring. It withstands heavy pressure, keeping panels aligned and stable to achieve accurate concrete shapes. Tie rods are reusable, durable, and essential in formwork systems. 

 A Wing Nut is a fastening accessory used with tie rods in formwork systems. Its wing-like design allows easy tightening and loosening by hand, ensuring quick assembly and disassembly of formwork.

 A Flange Nut is a heavy-duty nut used with tie rods to secure and stabilize formwork panels. Its wide base distributes load evenly, reducing surface pressure and ensuring a firm hold during concrete works.
