Energy

Custom fasteners and precision parts for energy applications, including parts used in electrical connection, structural fixing, coating-sensitive assemblies, and demanding service environments.

What fasteners are used in solar panel mounting systems, and can you make non-standard ones?

Common solar mounting fasteners include stainless steel 304/316 hex bolts, T-bolts, spring nuts, self-tapping screws with EPDM washers, anti-theft screws, U-bolts, and wedge anchors. For non-standard needs, we customize dimensions (e.g., extra-long M12×210mm), thread types (left-hand, stepped, reduced shank), head styles (low-profile, flanged serrated), coatings (zinc-aluminum, hot-dip galvanizing, duplex), anti-loosening features (nylon patch, deformed thread), and materials (titanium grade 2, anti-galling alloys).

All non-standard parts come with dimensional and salt spray test reports (ASTM B117) plus torque-tension validation. Quantity requirements vary by product – send us your drawing or sample for a tailored solution.

Common Concerns

• Corrosion resistance in real service environments
  Energy equipment is often exposed to outdoor, humid, or temperature changing conditions, so surface treatment and material selection directly affect service life and appearance stability.
• Structural stability under vibration and long term use
  In many energy applications, fasteners must maintain reliable clamping and positional stability over time, especially in equipment exposed to transport, operation vibration, or repeated loading.
• Fit consistency in batch assembly
  Small variation in dimensions, thread quality, or mating performance can create assembly inefficiency, unstable engagement, or difficulty in maintaining consistent installation across batches.
• Compatibility with different materials and assembly structures
  Fasteners often need to work with steel, aluminum, coated parts, electrical enclosures, or custom brackets, so design matching is important for both function and manufacturability.
• Reliability across custom designs and production scaling
  Energy projects often involve project based development, drawing based customization, and volume transition from samples to repeat orders, which makes process stability and specification control more critical.

Typical Scenarios

• Battery energy storage systems
  Fasteners used in battery racks, enclosure structures, internal support parts, busbar related assemblies, and auxiliary hardware where dimensional consistency and stable assembly are important.
• Solar mounting and supporting hardware
  Used in brackets, frame connections, support structures, and related metal assemblies where outdoor exposure, structural stability, and long term reliability matter.
• Power distribution and control equipment
  Applied in cabinets, control boxes, electrical enclosures, and supporting structures where fastening consistency affects assembly quality and service access.
• Inverter and converter related assemblies
  Used in structural frames, housing parts, mounting points, and internal fixing positions where fit, vibration resistance, and surface condition influence final assembly stability.
• General energy equipment and supporting hardware
  Suitable for custom metal parts and fastening structures used in energy related devices where the connection needs to match specific material, structure, and operating conditions.
