Heavy Hex Coil Nuts

Heavy Hex Coil Nuts – Durable Fastening for Concrete Formwork
Heavy hex coil nuts are high-strength fasteners designed for medium and heavy-duty concrete form applications. Manufactured through cold forming or hot forging, these hex nuts provide superior load-bearing capacity, making them ideal for use in high-stress construction environments.
These heavy-duty coil nuts are commonly used with she bolts, taper ties, coil bolts, and coil rods, ensuring secure fastening in formwork, scaffolding, and structural concrete projects.
Key Benefits of Heavy Hex Coil Nuts
- Coil thread design enables fast and easy installation and removal, reducing labor time on job sites.
- Self-cleaning threads allow for multiple uses, preventing debris buildup and ensuring reliable performance.
- High load capacity provides safe working loads required for demanding concrete and structural applications.
- Versatile compatibility with coil rods, coil bolts, taper ties, and she bolts for various construction setups.
- Manufactured from low carbon steel, ensuring durability and strength for repeated use.
- Customizable material and finish options available upon request.
Common Applications of Heavy Hex Coil Nuts
- Concrete forming systems – Securing and tensioning formwork panels.
- Scaffolding and structural supports – Providing stability in temporary and permanent construction.
- Bridge and highway construction – Ensuring reliable fastening in high-load environments.
- Industrial and commercial construction – Used in foundation systems and heavy-duty structures.
