The nylon insert creates interference against the mating thread, resisting loosening caused by vibration and torque. At 39\/64 inches high with 3\/4 inches across the flats, this nut meets standard UNC fastener dimensions and is driven with a 3\/4-inch wrench. The zinc yellow dichromate coating provides a baseline level of corrosion resistance for general industrial and mechanical applications. Sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for bolted assemblies in industrial equipment, structural fabrication, automotive, and mechanical maintenance applications where vibration resistance is required. The UNC 1\/2-13 thread size is one of the most common inch-series fastener sizes, making this nut a standard replacement or stocking item for maintenance shops, fabrication facilities, and trade contractors working with inch-system hardware. The Grade 8 steel construction handles higher clamping loads than Grade 5 equivalents, appropriate for medium-to-high-stress fastener joints.\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-strength, high-torque fastener joints\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish for corrosion resistance in general service environments\u003c\/li\u003e\n\u003cli\u003eUNC 1\/2-13 thread standard, right-hand thread direction\u003c\/li\u003e\n\u003cli\u003e39\/64 inches height and 3\/4 inches width across flats match standard inch-series tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/2-13 UNC inch-series threaded fasteners in standard bolted assemblies.

Torque the nut to the value specified by the assembly drawing or applicable fastener standard for Grade 8 hardware. Nylon insert lock nuts are generally intended for single use — once the nylon has been compressed by a mating thread, the locking effectiveness is reduced if the nut is reused. Do not use in applications where service temperatures will degrade or melt the nylon insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread 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: Grade 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Style\u003c\/strong\u003e: Nylon Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Nylon\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\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: R52001609\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689757540658,"sku":"R52001609","price":1248.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8f795475b23b8716bfce248909a24e7.jpg?v=1788263943","url":"https:\/\/voomisupply.com\/products\/value-collection-r52001609-hex-lock-nut-1-2-13-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
