Serrated Flange Hex Nut-Hexagon Flange Nut 304 Stainless Steel 18-8 DIN6923

描述

1. Anti-Vibration, Corrosion-Proof Performance
   • Manufactured to DIN 6923 from austenitic 18-8 (304) stainless steel, the nut provides ≈ 700 MPa tensile strength while retaining full ductility from −200 °C to +400 °C.
   • An integral 120° serrated flange bites into mating surfaces, generating prevailing-torque resistance up to 1.5 Nm per millimetre of thread diameter and preventing loosening under shock or vibration—without damaging protective coatings on the joint members.
   • The bright, passivated finish forms a self-healing chromium-oxide film that resists salt-spray, mild acids, cleaning detergents, and atmospheric humidity, ensuring long-term stainless appearance in wash-down or outdoor environments.
   • Roll-formed ISO-metric Class 6H female threads run the full nut height, maximising contact area and distributing axial load evenly to minimise galling or creep during repeated service cycles.
2. Versatile, Cross-Industry Application Spectrum
   • Machinery, Robotics & Automation: Secures motor mounts, gearbox covers, and sensor brackets where vibration damping and electrical continuity are required.
   • Automotive, Rail & Off-Highway Vehicles: Locks suspension linkages, brake shields, and exhaust hangers, with the serrated flange eliminating the need for spring washers in dynamic duty.
   • Food, Pharmaceutical & Clean-Room Equipment: Stainless construction and smooth external surfaces make the nut suitable for mixer guards, conveyor rails, and sterile enclosures subjected to frequent chemical wash-downs.
   • Renewable Energy & Marine Hardware: Attaches solar-panel frames, tidal-generator housings, and offshore lighting fixtures, resisting chloride-rich atmospheres and UV exposure while providing tool-less anti-rotation on pre-painted structures.
3. Fast, Operator-Friendly Handling
   • One-piece flange replaces separate washers, cutting parts count and installation time by up to 40 % in high-volume assembly or field repairs.
   • Chamfered lead-in guides the mating bolt or stud, allowing nuts to start by hand even in blind or overhead positions, and reducing cross-thread risk.
   • Standard hex profile fits all common hand, pneumatic, and battery drivers; the wide flange automatically centres on slotted holes, ensuring consistent seating without torque-controlled tools.
   • Supplied in bulk cartons, resealable service packs, or tape-and-reel strands for automated pick-and-place feeders, supporting everything from emergency kits to fully robotic production lines.
4. Premium Quality & Full Traceability
   • Every batch undergoes 100 % optical inspection for flange concentricity ≤ 0.03 mm TIR, serration height uniformity, and burr height < 0.05 mm; statistical data are logged for ISO 9001, IATF 16949, and PPAP Level 3 documentation.
   • Passivation follows ASTM A967 standards and can be supplemented with electropolishing to achieve Ra ≤ 0.4 µm for hygienic or decorative requirements without altering thread class.
   • Finish palette includes bright, matte, or black oxide plus colour powder-coat overlays in any RAL/Pantone shade, enabling brand identity or maintenance-zone coding while preserving dimensional accuracy.
   • Shipments arrive with RoHS 3, REACH, and DFARS material certificates, each nut tagged by QR code to its melt lot, assuring end-to-end supply-chain transparency for critical infrastructure, aerospace tooling, and medical devices.
