The nylon insert creates friction against the mating thread, resisting loosening caused by vibration and torque cycling. At 23\/64 inches high with a 1\/2-inch width across flats, this is a compact, high-strength fastener suited for assemblies where joint integrity under load is critical. The yellow zinc dichromate coating provides a baseline level of corrosion resistance. This nut is installed by mechanics, millwrights, HVAC technicians, and general trade professionals wherever a prevailing-torque locking fastener is specified.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is used in mechanical, HVAC, electrical, and general industrial assembly applications that call for a fine-thread, inch-series locking nut. The 5\/16-24 UNF thread designation makes it appropriate for applications requiring finer thread engagement and greater tension control than a coarse-thread equivalent. It is a right-hand thread fastener, tightened clockwise. Typical use cases include equipment panels, brackets, motor mounts, and structural assemblies where vibration resistance is required.\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 and proof-load strength\u003c\/li\u003e\n\u003cli\u003e5\/16-24 UNF right-hand thread for fine-pitch inch-series applications\u003c\/li\u003e\n\u003cli\u003eYellow zinc dichromate finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1\/2-inch width across flats fits standard hex tooling\u003c\/li\u003e\n\u003cli\u003e23\/64-inch height suits space-constrained fastening locations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5\/16-24 UNF inch-series threaded fasteners and bolts in general mechanical and trade assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a standard 1\/2-inch hex wrench or socket. Ensure the mating bolt thread is clean and free of debris before running the nut down. Power off or de-energize any equipment before performing fastener service on live assemblies. Do not reuse nylon insert lock nuts in safety-critical applications, as the nylon locking element loses effectiveness after the initial installation cycle.\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\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Yellow Zinc Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 23\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: MP39662\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701930557746,"sku":"MP39662","price":23.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83a7dc3ac2a72ae5e5ca511ff46b269a.jpg?v=1788407047","url":"https:\/\/voomisupply.com\/products\/value-collection-mp39662-hex-lock-nut-5-16-24-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
