DIN982 Carbon Steel Thickened Nylon Lock Nut

描述

1. High-Strength, Anti-Loosening Performance
   • Forged from heat-treated medium-carbon steel to Property Class 8 (≈ 800 MPa tensile), the nut endures heavy clamp loads without thread shear or collar distortion.
   • A thick PA 6 nylon insert is seated 1 mm deeper than standard, generating prevailing-torque retention after 15 + reuses and resisting vibration up to 14 g RMS.
   • A uniform ≥ 8 µm zinc coating—available in clear, yellow, black, olive, or rainbow chromate—delivers ≥ 120 h neutral-salt-spray protection (ISO 9227) and enables quick colour coding for maintenance zones or part identification.
   • Roll-formed ISO-metric Class 6H threads run the full nut height, distributing stress evenly and minimising galling during repeated service cycles.
2. Broad, Cross-Industry Application Spectrum
   • Powersports & Small-Engine Assemblies: Replaces OEM lock nuts on suspension arms, steering stems, and electrical brackets of motorcycles, scooters, ATVs, and utility vehicles.
   • Automotive, Rail & Off-Highway Equipment: Locks body mounts, brake-shield studs, and drivetrain brackets where dynamic loads and temperature swings would loosen plain hardware.
   • Machinery, Robotics & Automation: Secures motor mounts, sensor frames, and conveyor guards, maintaining electrical isolation and vibration resistance without additional washers.
   • Agricultural, Marine & Renewable-Energy Systems: Fastens pump housings, deck hardware, and turbine-frame covers exposed to moisture, fertiliser splash, or salt spray—optional duplex coatings mitigate galvanic corrosion on dissimilar substrates.
3. Technician-Friendly, Time-Saving Handling
   • Chamfered lead-ins allow nuts to start by hand even in blind or overhead positions, reducing cross-thread risk and installer fatigue.
   • Nylon insert engages only on the final turns, so the nut spins freely until clamp load is required, lowering driver-torque demand and prolonging battery life in powered tools.
   • Standard hex profile fits all common spanners, sockets, and impact drivers; tactile “bite” feedback when the prevailing-torque zone is reached simplifies quality checks without torque-angle gauges.
   • Supplied in convenient 50-piece cartons or resealable pouches that fit field-service kits, vending machines, and automated pick-and-place feeders.
4. Verified Quality & Full Traceability
   • Every production lot undergoes 100 % optical inspection for thread concentricity ≤ 0.03 mm TIR, insert depth ± 0.1 mm, and prevailing torque per ISO 2320; Cp/Cpk data are archived for ISO 9001, IATF 16949, and PPAP Level 3 records.
   • Metal surfaces are shot-blasted to Ra ≤ 1.6 µm before plating, reducing friction and easing future disassembly; inserts are moulded from virgin PA 6 with REACH and RoHS 3 compliance.
   • Optional powder-coat overlays in any RAL/Pantone shade support brand identity, line-side part picking, or low-visibility requirements without affecting thread class.
   • Each package carries QR-coded labels that trace every nut back to its melt lot and torque-test record, ensuring end-to-end supply-chain transparency for critical infrastructure, aerospace tooling, and medical-device assemblies.
