Wing Nut

Product Details

A construction wing nut is a galvanized or stainless steel fastener featuring two protruding wings for hand-tightening, designed for quick assembly/disassembly in formwork, scaffolding, and temporary structures. Its corrosion-resistant coating withstands outdoor exposure, while the broad wing design provides secure grip even with gloves. The nut’s coarse threads ensure compatibility with standard tie rods and bolts, offering tool-free adjustment in tight spaces. Reinforced base distributes load evenly, preventing deformation under tension. Commonly used in applications requiring frequent adjustments like concrete bracing, falsework, and modular frameworks. The wing nut’s simple design allows rapid installation without specialized tools, making it ideal for time-sensitive construction tasks.

Description and Components:

A manually operated fastener designed for quick assembly in temporary structures, featuring dual lateral wings for hand tightening without tools. Manufactured from weather-resistant materials like zinc-plated carbon steel or 304 stainless steel, it incorporates deep-cut threads for secure engagement with tie rods and construction bolts. The wing-to-body ratio is optimized for both torque application and space efficiency in confined work areas. Common applications include adjustable bracing systems, modular formwork, and scaffold joints where rapid installation is prioritized over permanent fastening. The design may include knurled wing edges for improved grip in wet or gloved conditions.

Functionality:

• Ergonomic Handling – Wing design enables secure grip even with work gloves, improving job site safety.
• Speed Adjustment Capability – Permits instant tension modifications during formwork alignment or scaffolding setup.
• Weather-Resistant Operation – Remains functional in wet/muddy conditions where tool sockets might slip.
• Tactile Torque Control – Provides physical feedback during hand-tightening to prevent joint overloading.
• Emergency Compatibility – Functions as backup fastener when power tools or standard nuts are unavailable.

Applications:

• Modular Formwork Systems – Enables rapid assembly and adjustment of reusable concrete molds.
• Temporary Safety Railings – Facilitates quick installation/removal of fall protection systems on evolving structures.
• Adjustable Concrete Spacers – Allows precise positioning of rebar mats before pouring.

• Tensioning Systems for Fabric Structures – Simplifies periodic adjustment of membrane or tarp tensions.
• Emergency Structure Repairs – Provides immediate fastening solution for temporary stabilization of damaged elements.

Advantages:

• Labor Efficiency – Reduces installation time by 50% compared to standard nuts, accelerating project timelines.
• Cost-Effective Maintenance – Eliminates tool replacement expenses with all-hand operation.
• All-Weather Reliability – Performs consistently in temperature extremes (-20°C to 50°C) without lubrication.
• Error-Proof Installation – Intuitive design prevents cross-threading common with power tool applications.

Inventory Simplification – Replaces multiple specialized fasteners with one universal solution across trades.
