Key Features of the L&T Wing Nut
1. High-Strength Cast Iron Body
We cast every wing nut from durable iron, so it handles impact, pressure, and repeated use without losing performance.
2. Smooth and Accurate Threading
We machine the threads precisely, and the nut grips the tie rod cleanly. As a result, tightening feels smooth, and the connection stays strong.
3. Compatibility With Multiple Tie Rod Sizes
This nut fits widely used tie rods — 12mm, 16mm, 20mm, and 25mm. Therefore, contractors can use it across different formwork setups.
4. Easy to Handle and Install
The wing design allows fast tightening without tools. Consequently, workers save time and reduce effort during assembly.
Applications of the Wing Nut
The L&T Cast Iron Wing Nut is widely used in:
-
Formwork shuttering systems
-
Tie rod and anchor assemblies
-
Column, wall, and beam formwork
-
Civil infrastructure projects
-
High-rise and commercial building construction
-
Heavy-duty concrete works
The nut ensures a secure lock on tie rods, keeping formwork panels aligned and stable during concrete placement.

Where and Why It Is Used
The L-Type Wing Nut plays a critical role in securing tie rods at the ends of wall formwork. Its extended L-shaped arm offers extra leverage, allowing workers to tighten rods more effectively by hand compared to a standard wing nut. Because it enables higher torque with less effort, it improves both safety and productivity during assembly.
The cast iron body handles high concrete pressure without deforming, and the optional zinc-plated finish provides excellent corrosion resistance for long-term outdoor use.
FAQs About L&T Cast Iron Wing Nut
Q1: What is the advantage of an L-Type Wing Nut over a standard wing nut?
