Nylock Nut Hex Nylon Insert Self Lock Nut Carbon Steel DIN985

描述

1. Robust, Color-Customizable Performance
   • Cold-forged from heat-treated medium-carbon steel to Property Class 8 (≈ 800 MPa tensile), the locknut handles high clamp loads without thread shear or collar distortion.
   • A precision-moulded PA 6 nylon insert sits 1 mm deeper than standard profiles, supplying prevailing-torque resistance that survives 15 + installation cycles and vibration levels to 14 g RMS.
   • Factory zinc plating (≥ 8 µm) with trivalent passivation provides ≥ 120 h neutral-salt-spray protection (ISO 9227). Overlays in clear, yellow, black, olive, rainbow zinc, or any RAL/Pantone powder coat add visual coding without altering tolerance.
   • Roll-formed ISO-metric Class 6H threads run the full nut height, distributing stress evenly and reducing galling during repeated maintenance.
2. Broad, Cross-Industry Application Spectrum
   • Transportation, Powersports & Mobility: Replaces OEM hardware on suspension arms, steering stems, and battery brackets for motorcycles, ATVs, e-bikes, and light vehicles subject to shock and temperature cycling.
   • Machinery, Robotics & Automation: Secures motor mounts, linear-guide carriages, and sensor frames, keeping joints tight without spring washers and maintaining electrical isolation.
   • Construction, Renewable Energy & Outdoor Fixtures: Locks solar-panel rails, HVAC mounts, and turbine covers exposed to UV, moisture, and wind-induced vibration—coloured coatings aid trade discipline identification.
   • Agricultural, Marine & Fluid-Handling Systems: Fastens pump housings, deck hardware, and fertilizer sprayer frames where corrosion resistance and nylon insulation prevent galvanic couples on dissimilar substrates.
3. Technician-Friendly, Time-Saving Handling
   • Chamfered lead-ins let the nut spin on quickly by hand, lowering cross-thread risk in blind or overhead positions.
   • Nylon insert engages only during the final turns, minimising driver torque demand and extending battery life for cordless tools.
   • Standard hex profile fits all common wrenches, sockets, and impact drivers; tactile “bite” feedback signals when prevailing-torque is achieved, simplifying pass-fail checks without gauges.
   • Supplied in resealable pouches, 50-piece cartons, or tape-and-reel strands—ready for field kits, vending machines, and automated pick-and-place feeders.
4. Verified Quality & Full Traceability
   • Each lot receives 100 % optical inspection for thread concentricity ≤ 0.03 mm TIR, insert depth ± 0.1 mm, and prevailing torque per ISO 2320; Cp/Cpk data archived for ISO 9001 and IATF 16949 compliance.
   • Shot-blasted surfaces achieve Ra ≤ 1.6 µm before plating, reducing friction and easing future disassembly; nylon is moulded from virgin PA 6 compliant with RoHS 3 and REACH.
   • Optional powder-coat overlays deliver colour durability > 1 000 h Q-SUN Xenon testing, meeting brand-identity or stealth requirements without affecting thread class.
   • QR-coded labels trace every nut to its melt lot and torque-test record, guaranteeing full supply-chain transparency for critical infrastructure, aerospace tooling, and medical-device assemblies.
