Manufactured from 18-8 \/ A2 stainless steel with a bright, uncoated finish, this nut provides corrosion resistance suited to wet, outdoor, or chemically exposed environments. The nylon insert compresses against the thread flanks when driven, creating prevailing torque that resists loosening under dynamic loads. With a 30 mm width across flats and a 20 mm height, it meets DIN 985 dimensional standards. Licensed trades and industrial maintenance technicians install this fastener in mechanical assemblies, structural connections, and equipment mounts where a positive thread lock is required.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is used in residential and commercial mechanical installations, as well as industrial equipment and infrastructure applications requiring M20 metric threading. Right-hand thread direction makes it compatible with standard metric fastener tooling. The DIN 985 standard governs its dimensional tolerances, making it an interchangeable replacement in assemblies specified to that standard. Typical install scenarios include HVAC equipment frames, pump and motor mounts, pipe supports, and structural steel connections where stainless steel fasteners are specified for corrosion performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking mechanism resists loosening caused by vibration and dynamic loading\u003c\/li\u003e\n  \u003cli\u003e18-8 \/ A2 stainless steel construction provides corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 985 dimensional standard for interchangeability in metric assemblies\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no plating to flake, chip, or introduce contamination\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard metric tooling\u003c\/li\u003e\n  \u003cli\u003eM20x2.5 thread size suits heavy mechanical and structural fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M20x2.5 right-hand threaded fasteners and bolts conforming to standard metric thread profiles.

Ensure mating bolt threads are clean and free of debris before driving the nut to avoid damaging the nylon insert. The nylon insert is single-use — once the nut has been fully driven and removed, it should not be reused, as the insert loses prevailing-torque effectiveness. De-energize or depressurize any system before working on fastened assemblies.\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 with Nylon Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x2.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 \/ A2 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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: 122597\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711166873906,"sku":"122597","price":45.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15a50ec16b9219efaa73f86e33b4b93c.jpg?v=1788474934","url":"https:\/\/voomisupply.com\/products\/value-collection-122597-hex-lock-nut-m20x2-5-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
