Corrosion-Resistant Performance<br \/>\n\u2022 Built to DIN 982 and offered in two material grades\u2014A2-70 (18-8\/304) and A4-80 (316 Mo-bearing)\u2014the lock nut delivers tensile strengths of \u2248 700 MPa and \u2248 800 MPa respectively while retaining ductility from \u2212200 \u00b0C up to +400 \u00b0C (metal portion).<br \/>\n\u2022 The extra-thick PA 6 nylon collar is press-fitted 1 mm deeper than standard inserts, generating prevailing-torque retention even after 15+ reuses and resisting vibration loosening up to 14 g RMS.<br \/>\n\u2022 Stainless alloy forms a self-healing chromium-oxide film, providing long-term resistance to salt spray, mild acids, cleaning detergents, and outdoor humidity; A4-80 adds molybdenum for superior pitting protection in chloride-rich or chemical environments.<br \/>\n\u2022 Nylon insert remains functional to +120 \u00b0C continuous and +140 \u00b0C short-term, with UL 94 HB flame rating and dielectric strength &gt; 15 kV \/mm\u2014ideal for electrically insulated joints.<\/li>\n<li>Wide-Ranging Industrial &amp; Commercial Applications<br \/>\n\u2022 Transportation &amp; Mobility: Secures chassis brackets, brake shields, and fuel-system hangers on cars, railcars, e-bikes, and light aircraft where maintenance intervals are extended.<br \/>\n\u2022 Food, Beverage &amp; Pharmaceutical Equipment: Locks mixer guards, sanitary pipe clamps, and autoclave doors in wash-down zones without galling or bacterial entrapment.<br \/>\n\u2022 Marine, Offshore &amp; Renewable Energy: Fastens deck hardware, winch housings, turbine nacelle covers, and solar-tracker frames exposed to cyclic loading, UV, and salt spray\u2014A4-80 recommended.<br \/>\n\u2022 Electronics, Instrumentation &amp; HVAC: Holds PCB standoffs, sensor enclosures, and ventilation panels where nylon isolation prevents galvanic couples and stray current paths.<\/li>\n<li>Technician-Friendly, Time-Saving Handling<br \/>\n\u2022 Chamfered lead-ins and roll-formed ISO-metric Class 6H threads ensure smooth hand-starting, lowering cross-thread risk during blind, overhead, or glove-hand installations.<br \/>\n\u2022 The nylon collar engages only on the final turns, so nuts spin freely until clamp load is required, reducing driver torque demand and battery drain in powered tools.<br \/>\n\u2022 Compatible with all standard hex sockets and wrenches; thick collar offers tactile \u201cbite\u201d feedback when the prevailing torque zone is reached, simplifying quality checks without torque-angle gauges.<br \/>\n\u2022 Delivered in vibration-proof trays, resealable pouches, or tape-and-reel formats that feed manual benches as well as automated pick-and-place systems.<\/li>\n<li>Certified Quality &amp; Full Traceability<br \/>\n\u2022 Each production lot undergoes 100 % optical inspection for thread concentricity \u2264 0.03 mm TIR, nylon insertion depth \u00b1 0.1 mm, and prevailing torque per ISO 2320; Cp\/Cpk data archived for ISO 9001, IATF 16949, and PPAP Level 3 documentation.<br \/>\n\u2022 Metal components are passivated per ASTM A967; inserts moulded from virgin PA 6 with REACH and RoHS 3 compliance.<br \/>\n\u2022 Optional electropolishing achieves Ra \u2264 0.4 \u00b5m for aseptic or decorative requirements; colour-coding of nylon (natural, blue, red, or black) aids line-side identification of thread sizes or torque classes.<br \/>\n\u2022 Each package bears QR-coded labels linking every nut to its melt lot and torque-test record, ensuring end-to-end supply-chain transparency for aerospace, medical, and critical-infrastructure applications.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"<p>Superior Anti-Loosening &amp;
