Tie Rod Nut

A tie rod nut in construction is a heavy-duty steel fastener, typically galvanized for corrosion resistance, used to secure threaded tie rods in formwork, concrete reinforcement, or bracing systems. It features coarse or fine threads (e.g., M16, M20) and is tightened against washers or couplers to maintain structural stability. Common types include hex nuts, flange nuts, or locking nuts (with nylon inserts for vibration resistance). These nuts ensure tension integrity in formwork, rebar ties, or temporary bracing, often torqued to specific loads and paired with washers for even pressure distribution.

Product Details

A heavy-duty construction tie rod nut features hot-dip galvanized steel construction for superior corrosion resistance in harsh environments. The precision-forged component boasts a flanged design with anti-slip ribs that maintain clamping force under vibration and dynamic loads. Its coarse threads ensure quick installation while the reinforced base distributes stress evenly across contact surfaces. The nut incorporates six flat wrenching surfaces for secure tool engagement and features a self-locking mechanism that prevents loosening without requiring additional fasteners. Engineered for structural applications, it offers high tensile strength with consistent performance in concrete formwork, bracing systems, and reinforcement assemblies. The durable zinc coating provides long-term protection against weather, chemicals, and abrasion throughout construction cycles.

Description and Components:

A heavy-duty forged steel nut, hot-dip galvanized for corrosion resistance, designed to secure tie rods in formwork and structural bracing systems. It features a flanged base for load distribution, coarse threads for quick installation, and anti-vibration ribs to prevent loosening under dynamic loads. The nut includes wrench flats for tool engagement and may incorporate a self-locking mechanism (nylon insert or deformed threads) for added security. Its durable zinc coating ensures long-term performance in harsh construction environments. The assembly typically works with washers and threaded tie rods to create stable structural connections in concrete reinforcement and temporary bracing applications.

Functionality:

Secure Fastening – Locks tie rods firmly in place to maintain structural stability in formwork and bracing systems.
Load Distribution – Flanged design spreads clamping force evenly to prevent localized stress on connected components.
Vibration Resistance – Anti-loosening features (ribs, nylon inserts, or deformed threads) prevent nut detachment under dynamic loads.
Corrosion Protection – Hot-dip galvanized coating ensures durability in harsh environments like wet concrete or outdoor sites.
Quick Installation – Coarse threads allow for rapid assembly and disassembly, improving construction efficiency.

Applications:

Formwork Systems – Used to secure tie rods in concrete formwork for walls, columns, and slabs.
Structural Bracing – Provides stability in temporary bracing and shoring structures during construction.
Concrete Reinforcement – Maintains alignment and tension in rebar and post-tensioning systems.
Scaffolding & Support Frames – Ensures rigid connections in modular scaffolding and falsework assemblies.
Bridge & Tunnel Construction – Essential for securing heavy-duty tie rods in civil engineering projects.

Advantages:

High Strength & Durability – Forged steel construction provides superior load-bearing capacity for heavy-duty applications.
Corrosion Resistance – Hot-dip galvanized or coated finish ensures long-term performance in harsh environments.
Vibration Resistance – Locking mechanisms (flange, nylon insert, or ribbed design) prevent loosening under dynamic loads.
Quick Installation – Coarse threads enable fast assembly and disassembly, improving work efficiency.

Versatile Compatibility – Designed to work with standard tie rods and tools across various construction systems.
