Are your wing nuts compatible with standard M16 tie rods?

Yes, Avanza wing nuts are machined to fit ISO-standard M16 × 2.0 threads.

What size washer should be used with these nuts?

A Ø 65 mm chamfered flat washer ensures even pressure distribution and alignment.

Can I reuse these nuts for multiple projects?

Absolutely, each nut is built for over 200 uses under standard site conditions.

Are other diameters available?

Yes, we also supply M20 and M22 sizes on demand, but M16 is the standard stock variant.

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.

Integration with Tie Rod Systems

Avanza's M16 wing nuts are fully compatible with M16 tie rods, making them ideal for:

Wall formwork pressure retention
Column form tie-backs
Bridge shuttering
Slab edge beam bracing

Each nut threads smoothly onto the tie rod, clamping shuttering panels and distributing load across washers.

Installation Workflow

Insert the M16 tie rod through the shuttering panel holes.
Place a Ø 65 mm washer on both ends.
Manually tighten the M16 wing nut to secure the system.
Dismantle post-casting for reuse.
