Built to Grade 8 steel standards and finished with a yellow zinc dichromate coating for corrosion protection, this nut accepts a 1\/2-13 UNC right-hand thread. The nylon insert deforms around mating threads to resist loosening under dynamic loads. At 39\/64 inches high with 3\/4 inches across the flats, it fits standard 3\/4-inch hex tooling. Installed by mechanical contractors, industrial maintenance technicians, and equipment fabricators wherever a secure, reusable locking fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis nut is suited for general industrial, mechanical, and structural assembly work using 1\/2-13 UNC fasteners. It performs in environments subject to vibration, thermal cycling, or dynamic loading where a standard hex nut would back off over time. The yellow zinc dichromate finish provides a visible corrosion barrier appropriate for indoor and light-exposure applications. Minimum order quantity is 25 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening under vibration and dynamic loads\u003c\/li\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003eYellow zinc dichromate finish provides corrosion resistance and visual identification\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC right-hand thread — standard inch fastener series\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch width across flats fits common standard hex tooling\u003c\/li\u003e\n  \u003cli\u003eReusable design allows removal and reinstallation without sacrificing locking function in low-cycle applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-13 UNC right-hand threaded fasteners in standard inch-series assemblies.

Ensure mating bolt threads are clean and free of debris before driving the nut to final torque. Do not use impact tools at high speed, as this can damage the nylon insert and reduce locking effectiveness. Consult the applicable fastener torque specification for the joint design — do not rely on feel alone for Grade 8 hardware.\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: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\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: 39\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/4 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\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: 39655\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715778838834,"sku":"39655","price":39.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/870781682d4a91504c205ef94b1d5764.jpg?v=1788518237","url":"https:\/\/voomisupply.com\/products\/value-collection-39655-hex-lock-nut-1-2-13-grade-8-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
