Wing nut- Galvanized Carbon steel Round Wing Nut Fastener Hardware Part

描述

1. Performance & Material Properties
   • High-Strength Carbon & Alloy Steel Core: Forged from quenched-and-tempered C1045 carbon steel or 4140 alloy steel, delivering tensile strengths of 800–950 MPa and Rockwell hardness of 35–45 HRC for exceptional shear and pull-out resistance.
   • Dual Corrosion Barriers & Color Customization: First, a trivalent zinc plating (8–12 µm) with yellow or clear chromate passivation provides ≥240 h salt-spray protection (ASTM B117). Optionally, an epoxy-polyester powder coat (30–50 µm) adds UV-stable, scratch-resistant color finishes (black, red, blue, green, custom RAL) for easy visual identification.
   • Precision-Rolled UNC/Metric Threads: Coarse and fine pitches (e.g. ¼-20, M6–M12) are cold-rolled to boost root strength, ensure smooth engagement, and minimize cross-threading during repeated adjustments.
   • Ergonomic Round-Wing Design: Smooth, circular wings distribute finger torque evenly (up to 2 Nm), feature radiused edges to prevent snagging, and maintain a low profile for installation in tight or overhead spaces.
2. Detailed Application Range
   • Mechanical & Equipment Assembly: Secures guards, brackets, and jigs on presses, conveyors, and test fixtures—tool-free access speeds maintenance.
   • Electronic Enclosures & Panels: Fastens removable covers, PCB mounts, and cable clamps in control cabinets, telecom racks, and lab instruments where EMI shielding and quick servicing are required.
   • Furniture & Decorative Fixtures: Ideal for modular shelving, picture frames, display stands, and trim pieces—color-coded wings match décor and simplify workshop organization.
   • Trade-Show & Retail Displays: Used in exhibition booths, signage, and point-of-sale fixtures for rapid tool-free setup, teardown, and reconfiguration.
3. Effortless Operation & Convenience
   • Tool-Free Hand Tightening: Round wings deliver up to 2 Nm of torque by hand, eliminating wrenches even in confined spaces or at height.
   • Quick-Release & Repeatable Use: Smooth-start threads and tight tolerances minimize galling—nuts back off cleanly for fast component removal and can be reused hundreds of times without performance loss.
   • Color-Coded Identification: Powder-coat finishes enable instant size or function recognition, reducing installation errors and downtime.
   • Organized Assortment Kits: Available in 50–200 piece kits covering common UNC/Metric sizes, each in labeled, compartmentalized cases for fast selection.
4. Superior Quality & Long-Term Reliability
   • International Standards & Certification: Produced in ISO 9001–certified plants to ANSI/ASME B18.6.9 and ASTM A563 tolerances (±0.1 mm), ensuring interchangeability and dimensional accuracy.
   • Rigorous Testing & Traceability: Each batch undergoes salt-spray (ASTM B117), torque-to-turn, and dimensional inspections; parts are lot-coded with mill certificates for full traceability.
   • Environmental & Safety Compliance: RoHS- and REACH-compliant; free of hexavalent chromium and other restricted substances. Powder-coat finishes meet UL 94 V-0 flame retardancy where required.
   • Maintenance-Free Service Life: The combination of alloy-steel strength, dual corrosion barriers, and precision workmanship delivers decades of vibration-resistant, rust-free performance—even under cyclic loads and harsh environments.
