Wing Nuts: Robust and Reliable Fastening Solutions for Every Project
Scaffolding wing nuts—often paired with tie rods and anchor nuts—are the small yet critical components that secure your formwork under intense concrete pressures. At Avanza Steel, our wing nuts are engineered for repetitive use, ergonomic handling, and corrosion resistance, ensuring your scaffolding assemblies stay tight, aligned, and safe throughout the construction cycle.
What Is a Scaffolding Wing Nut?
A scaffolding wing nut is a threaded fastening device with two “wings” that allow rapid, tool-free tightening and release. In formwork systems, wing nuts engage the external thread of tie rods or anchor rods, pulling walers and shuttering panels into compression against wet concrete. Their large-profile wings enable easy operation even with gloved hands, speeding up assembly and stripping phases.
Key Benefits:
-
Ergonomic Design: Oversized wings permit firm grip and swift hand-tightening, reducing labor fatigue on high-volume projects.
-
High Reusability: Electro-galvanized finish and Grade 8.8 steel threads withstand over 200 tightening cycles without significant wear.
-
Corrosion Resistance: Hot-dip galvanization (minimum 85 µm zinc) shields threads and bearing surfaces in harsh, alkaline environments.
-
Precise Fit: Machined threads conform to IS 1367 tolerances, ensuring consistent preload and preventing play under load.
