It features a right-hand thread in M12x1.75 pitch and conforms to DIN 985 standards. The nylon insert creates a prevailing-torque locking action that resists loosening caused by vibration and dynamic loads. At 12.00 mm in height with a 19.00 mm width across flats, this fastener fits standard M12 hex tooling. It is suited for marine, chemical processing, food service, and other corrosive environments where 316-grade stainless is specified.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is used in mechanical assemblies, structural connections, and equipment installations where vibration resistance and corrosion resistance are both required. The DIN 985 standard makes it a direct fit in metric fastener applications across industrial maintenance, marine hardware, plumbing equipment mounts, and HVAC equipment frames. Installers working in wet or salt-air environments commonly specify Grade 316 A4 stainless hardware to meet corrosion resistance requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration per DIN 985\u003c\/li\u003e\n  \u003cli\u003eGrade 316 A4 stainless steel construction for superior corrosion resistance in marine and chemical environments\u003c\/li\u003e\n  \u003cli\u003eM12x1.75 right-hand thread for standard metric compatibility\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no plating to degrade in harsh exposure conditions\u003c\/li\u003e\n  \u003cli\u003e19.00 mm width across flats fits standard M12 hex wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003e12.00 mm nut height provides adequate thread engagement for full load capacity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on M12x1.75 metric threaded fastener assemblies conforming to DIN 985.

Nylon insert lock nuts are intended for single-use only — once the nylon insert has been fully seated and removed, the locking effectiveness is reduced and replacement is recommended. Ensure mating threads are clean and free of burrs before installation. This fastener should be installed by a qualified mechanic or tradesperson following applicable torque guidelines for M12 stainless fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 19.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 985\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NL5XX01200-050BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721693921586,"sku":"NL5XX01200-050BX","price":2379.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4ee88cc1538adeaacac6fc5e259d42d.jpg?v=1788579497","url":"https:\/\/voomisupply.com\/products\/value-collection-nl5xx01200-050bx-hex-lock-nut-m12x1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
