Custom Non-Standard Stainless Steel Shaft Pins for High Precision Assembly in

Custom Non-Standard Stainless Steel Shaft Pins are tailor-made CNC precision assembly parts exclusively designed for new energy module assembly, new energy vehicle equipment, and energy storage intelligent devices. Unlike standard shaft pins, our custom pins support full-size and full-structure personalized customization, including stepped, flat, slotted, tapered, and eccentric special-shaped structures, perfectly meeting non-standard positioning, limiting, and alignment demands of new energy precision assembly.

Manufactured from high-purity stainless steel via integrated CNC turn-milling machining, these custom pins feature strict tolerance control, burr-free surface, excellent concentricity, and high fitting accuracy. With outstanding anti-corrosion, anti-vibration, and fatigue-resistant performance, they are widely applied in new energy module positioning, battery tooling limiting, and electronic control module fixing, serving as essential non-standard hardware components for new energy precision assembly systems.

• New Energy Grade Material with Excellent Weather Resistance
  High-quality stainless steel provides outstanding rust-proof, acid-resistant, and moisture-resistant performance, far better than ordinary carbon steel pins. It stably adapts to humid workshop environments, vehicle temperature changes, and mildly corrosive working conditions of new energy scenarios, avoiding oxidation and surface failure, and extending service life for long-term equipment operation.
• Micron-Level CNC Precision Machining
  Multi-axis integrated CNC machining strictly controls outer diameter, length, concentricity, and verticality with ultra-tight tolerance. Smooth insertion and accurate repeated positioning fully meet the high-precision assembly standards of new energy electronic control modules, battery tooling, and vehicle precision components, effectively avoiding assembly errors caused by positioning deviation.
• Vibration & Fatigue Resistant for High-Frequency Operation
  Solid one-piece structure features dense texture and high rigidity, with excellent shock resistance and fatigue resistance. Optimized for continuous start-stop operation, vehicle vibration, and frequent module disassembly in new energy equipment, the shaft pins resist loosening, deformation, and position offset during long-term operation, ensuring stable and safe equipment operation.
• Maintenance-Free Design for Mass Equipment Matching
  The natural anti-rust and anti-corrosion properties of stainless steel eliminate the need for extra surface treatment. The pins are not easy to scale, rust, or jam during operation, perfectly matching the mass production and long-term maintenance-free demands of new energy equipment, greatly reducing later operation and maintenance costs.
• Full Non-Standard Customization for New Energy Modules
  We provide professional non-standard customization exclusive for the new energy industry. Without standard specification limitations, all special-shaped shaft pin structures can be customized strictly according to customer drawings, samples, and module assembly parameters, including step shoulders, bilateral flats, tapered guide tips, limit slots, and eccentric profiles. The custom pins adapt to narrow installation spaces, special assembly tracks, and exclusive limiting angles of new energy equipment. Supporting prototype sampling, small-batch commissioning, and large-batch mass production, our service fully matches the rapid iteration and customized production characteristics of new energy equipment.

• Precision positioning shaft pins for new energy vehicle electronic control modules
• Limit and guide pins for new energy battery tooling and testing jigs
• Fixed support shaft pins for energy storage and new energy intelligent equipment
