The nylon insert compresses against mating threads to resist loosening caused by vibration, torque, and thermal cycling. At 5\/16 inches high with a 7\/16-inch width across flats, this nut is sized for standard 1\/4-28 fine-thread fastener applications. It is installed by mechanics, millwrights, and maintenance technicians wherever a reliable, reusable prevailing-torque locking fastener is required.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for general industrial, mechanical, and structural assembly work using fine-thread 1\/4-28 fasteners. Right-hand thread direction matches standard fastener orientation. The Grade 8 steel construction provides high tensile strength for demanding load-bearing connections. Typical applications include machinery assembly, equipment mounting, and any joint subject to vibration that would loosen a standard hex nut over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening under vibration without damaging mating threads\u003c\/li\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile strength\u003c\/li\u003e\n\u003cli\u003e1\/4-28 UNF fine-thread specification for precise thread engagement\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard installation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for dry or lightly oiled environments\u003c\/li\u003e\n\u003cli\u003e5\/16-inch height and 7\/16-inch width across flats for use with standard 7\/16-inch wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a prevailing-torque replacement or serviceable lock nut for 1\/4-28 UNF fine-thread fastener assemblies in industrial and mechanical applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 7\/16-inch wrench or socket. Power down and de-energize any equipment before servicing fasteners on live assemblies. Nylon insert nuts are intended for use at moderate temperatures — verify suitability if installation location is subject to sustained elevated heat, as nylon inserts can lose locking force above certain temperature thresholds. Do not reuse a nylon insert lock nut if the nylon insert shows visible damage or no longer provides prevailing torque resistance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Type\u003c\/strong\u003e: Hex Lock Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF (Inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: R52001633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720528134450,"sku":"R52001633","price":1399.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2f3387058e4d1f327a3219d736efe96.jpg?v=1788565584","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001633-hex-lock-nut-1-4-28-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
