It is manufactured from Grade B steel with a zinc-plated finish that provides basic corrosion resistance. The nut features a 1-1\/4-12 UNF right-hand thread, a height of 1-25\/64 inches, and a width across flats of 1-13\/16 inches. The nylon insert collar deforms around mating threads to create a prevailing torque locking action without additional hardware. This fastener is installed by maintenance technicians, millwrights, and mechanical contractors across a wide range of industrial and structural assembly applications.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for bolted assemblies where vibration resistance is required and a standard hex nut is insufficient. Typical applications include machinery frames, equipment mounts, conveyor systems, and structural connections where a unified fine thread pitch is specified. The zinc plating makes it appropriate for indoor or lightly controlled environments. It is sold individually and is intended for single-use locking service, as repeated removal degrades the nylon insert's prevailing torque performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking mechanism provides vibration-resistant prevailing torque without secondary locking hardware\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-12 UNF right-hand thread for use in fine-thread bolted assemblies\u003c\/li\u003e\n  \u003cli\u003eGrade B steel construction meets standard mechanical property requirements for this nut size\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion protection in dry or lightly humid environments\u003c\/li\u003e\n  \u003cli\u003eWidth across flats of 1-13\/16 inches accepts standard open-end or box-end wrenches\u003c\/li\u003e\n  \u003cli\u003eDoes not meet military specifications — intended for commercial and industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1-1\/4-12 UNF externally threaded fasteners in inch-measurement bolted assemblies requiring a nylon insert prevailing torque lock nut per the UNF fastener standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a standard open-end, box-end, or socket wrench sized to the 1-13\/16 inch across-flats dimension. The nylon insert is a single-use locking feature — once fully seated and removed, the insert's locking torque is reduced and the nut should be replaced. Ensure the mating threaded fastener is clean and free of thread damage before installation to avoid compromising the insert. Follow applicable mechanical assembly codes and equipment manufacturer torque guidelines for the joint being assembled.\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: 1-1\/4-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNF\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: B\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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-25\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-13\/16 inches (1.801 to 1.815 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 2.038 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does not meet military specifications\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: B52001615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699007095090,"sku":"B52001615","price":19.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbf84ab8f01a8c5023150e701a1905a1.jpg?v=1788371063","url":"https:\/\/voomisupply.com\/products\/value-collection-b52001615-hex-lock-nut-1-1-4-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
