REACON supplies ASTM A153 hot dip galvanized nuts for overhead power line hardware, utility pole construction, and outdoor steel fastening applications. The product range includes hex nuts and square nuts, providing different structural options for fastening threaded bolts, rods, and other metal components.
Manufactured from steel and finished with a hot-dip galvanized zinc coating, these nuts are designed for outdoor installations where reliable thread engagement and protection against environmental exposure are required.
Hex nuts are commonly selected for general-purpose bolted connections, while square nuts are frequently used in utility hardware assemblies where their flat sides provide a larger contact area against supporting components. The appropriate type depends on the bolt design, installation space, thread specification, and assembly requirements.
1. Hot Dip Galvanized Hex Nut
The hex nut features a six-sided external shape, allowing it to be tightened with commonly used wrenches and fastening tools. It is suitable for threaded bolts, anchor rods, and structural connections used in power distribution equipment and outdoor steel structures.
Typical applications include:
• Utility pole bolts and threaded rods
• Anchor bolt connections
• Steel brackets and mounting assemblies
• Transmission and distribution line hardware
• Outdoor structural fastening
2. Hot Dip Galvanized Square Nut
The square nut has four flat sides and a wider bearing surface compared with a conventional hex nut of similar nominal thread size. This structure is commonly used in pole line hardware and utility fastening assemblies.
The square nut supplied by REACON is described as having Unified National Coarse (UNC) Class 2B threads, oversized where required for use with galvanized bolts and rods. Thread dimensions and tolerances should be confirmed against the applicable drawing and fastening specification.
Typical applications include:
• Crossarm and pole line hardware connections
• Utility pole brackets and support fittings
• Anchor bolts and threaded rods
• Electrical distribution structures
• Outdoor steel equipment assemblies

Two Nut Configurations for Different Assemblies
Hex nuts and square nuts provide alternative fastening structures for different utility hardware designs. Customers can select the appropriate configuration according to the mating bolt and installation conditions.
Galvanized Surface for Outdoor Use
The hot-dip galvanized coating helps protect the steel surface from corrosion during outdoor service. Coating requirements can be specified according to the applicable ASTM A153 provisions.
Thread Compatibility
Correct thread matching is essential for secure fastening. REACON can supply nuts according to specified thread diameter, pitch, series, and tolerance requirements.
Suitable for Utility Hardware Assemblies
These nuts can be incorporated into pole line fittings, anchor systems, mounting brackets, and other steel fastening assemblies.
Specification-Based Customization
Different dimensions, thread configurations, and product requirements can be discussed according to customer drawings or samples.
1. Overhead Power Transmission and Distribution
Used to fasten crossarms, brackets, support fittings, and other metal components in overhead line structures.
2. Utility Pole Construction
Suitable for connections involving pole line bolts, threaded rods, mounting hardware, and structural attachments.
3. Anchor and Guying Systems
Used with compatible anchor bolts, threaded rods, and related fittings in utility pole anchoring assemblies.
4. Telecommunication Structures
Applied to fastening connections on communication poles, tower accessories, and outdoor support frames.
5. Industrial Steel Structures
Used in outdoor steel frameworks, equipment supports, and other bolted assemblies requiring galvanized fastening components.
Before installation, select the nut according to the bolt or threaded rod specification. The thread type, nominal diameter, pitch, and tolerance must be compatible.
Recommended installation steps:
1. Check the bolt or threaded rod dimensions and thread specification.
2. Select the corresponding hex nut or square nut according to the assembly drawing.
3. Check the nut threads for damage or contamination before installation.
4. Position the nut correctly and tighten it with a suitable tool.
5. Apply the specified tightening torque according to the project or engineering requirements.
6. Inspect the completed connection to ensure proper engagement and fastening.
For galvanized fasteners, avoid forcing incompatible threads together, as this may damage the coating or affect installation quality.
REACON can arrange product inspection according to the confirmed order specifications. Relevant inspection items may include:
• Nut dimensions and external shape
• Thread size and compatibility
• Surface condition and galvanizing appearance
• Zinc coating thickness, where specified
• Material and mechanical requirements according to the agreed specification
Inspection requirements and supporting documents can be discussed before production.
REACON supplies fastening components for power transmission and distribution projects, including bolts, nuts, washers, and other pole line hardware.
With different nut configurations available, customers can source compatible fastening components for utility construction and outdoor steel assemblies. Customized specifications can be evaluated using technical drawings, samples, or project requirements.
