The nylon insert deforms around the mating thread to resist vibration-induced loosening without requiring a secondary locking element such as a washer or adhesive. Standing 7\/8 inches high with a 1-1\/16 inch width across flats, this fastener is sized for standard 3\/4-inch coarse-thread applications. It is installed by mechanics, millwrights, pipefitters, and general tradespeople wherever a secure, reusable threaded connection is required in light to medium-duty assemblies.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for structural, mechanical, and equipment-mounting applications that demand reliable thread retention under vibration or dynamic loading. The UNC thread form is the standard coarse-pitch inch series, making this nut compatible with a wide range of bolts, studs, and threaded rod stock used in HVAC equipment frames, electrical enclosures, pump and motor mounts, and general fabrication work. The zinc trivalent chromate finish provides a baseline level of corrosion resistance appropriate for indoor and protected outdoor installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening from vibration and torque cycling without secondary hardware\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction provides medium-strength performance for general mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish offers corrosion resistance and meets modern RoHS-compliant coating standards\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC right-hand thread matches the most common coarse-pitch inch-series bolt and stud stock\u003c\/li\u003e\n  \u003cli\u003eWidth across flats of 1-1\/16 inches accepts standard 1-1\/16 inch open-end, box, or socket wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation hex lock nut for 3\/4-10 UNC right-hand threaded fastener applications in mechanical, structural, and equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and de-energize any equipment before accessing fastener locations on live machinery. Use a calibrated torque wrench and follow the applicable equipment manufacturer torque specifications for Grade 5 fasteners at this thread size. Nylon insert lock nuts are intended for one-time use in critical joints, as the nylon insert loses clamping effectiveness after repeated removal and reinstallation. Verify thread condition on the mating bolt or stud before installation to ensure full thread engagement.\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: 3\/4-10 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: Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Trivalent Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 52591401-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710236000562,"sku":"52591401-100","price":27.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4194c4dbfe89d00f0910a2ba462fd07.jpg?v=1788464650","url":"https:\/\/voomisupply.com\/products\/value-collection-52591401-100-hex-lock-nut-3-4-10-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
