About Scaffolding Anchor Nut, Size: 90 Mm, Also Available In 100 Mm,130 Mm

Scaffolding Anchor Nut

Scaffolding Anchor Nut is a specialized construction/formwork accessory used with tie rods, anchor systems, and scaffolding support arrangements to provide secure fastening and load distribution. It is commonly used in concrete formwork, scaffolding systems, wall shuttering, and reinforcement-related applications, depending on the specific design.

A Scaffolding Anchor Nut (commonly called a Formwork Anchor Nut, Tie Nut, or Combination Flange Nut) is a specialized heavy-duty fastener used alongside tie rods (tie bars) to secure concrete formwork panels and anchor scaffolding ties to concrete structures.

Types, Materials, and Key Specifications

Anchor nuts come in a few common designs, with the two-wing and three-wing styles being the most prevalent. The choice of material directly impacts strength and durability.

Feature	Common Options & Specifications
Type	Two-Wing, Three-Wing, Swivel/Combi Nut (for angled surfaces)
Material	Ductile Cast Iron (e.g., QT450-10) - Standard choice, excellent impact resistance; Forged Steel - For extremely high-load applications
Tie Rod Fit	Typically designed for D15/17mm or M20/M22 tie rods
Base Diameter	Commonly 90mm or 100mm
Load Capacity	Can handle hydrostatic pressures up to 60 kN/m (with matching tie rod system)
Surface Finish	Hot-Dip Galvanized, Zinc-Plated, or Plain
Standards	Often manufactured to meet DIN 18216, BS1139, or EN74 standards

Key Features

Heavy-Duty Construction
Manufactured from strong steel to withstand the mechanical forces generated during construction and formwork operations.

Secure Threaded Connection
The internal threaded section allows the nut to engage with a compatible threaded rod or anchor component.

Load Distribution
The nut can help distribute tightening and applied loads over the connected assembly, depending on the system configuration.

Corrosion Protection
Surface finishes such as zinc plating or galvanizing can be provided to improve resistance to corrosion, especially in demanding construction environments.

Easy Installation
Designed for quick tightening with commonly used construction tools.

Multiple Sizes
Available in different thread sizes and configurations to match project-specific scaffolding and formwork requirements.

Installation & Best Practices

Installing an anchor nut is a straightforward process, but following proper procedures ensures safety and reusability.

Preparation: Ensure the threaded tie rod and the internal threads of the nut are clean and free of debris. Inspect for any signs of wear or corrosion.
Positioning: Slide the tie rod through the formwork panels or scaffold components. Place the required washer over the rod.
Tightening: Thread the anchor nut onto the rod by hand until it is snug. Use the wings to apply the final tightening force. For high-pressure pours, a hammer can be used to gently tap the wings for a secure fit.
Removal & Maintenance: After the concrete has gained sufficient strength (typically 70% of design strength), the nuts can be backed off and the rods withdrawn. Clean the nuts and rods after use, and store them in a dry place to prevent corrosion.
