The nylon insert deforms around the mating thread when the nut is driven down, creating resistance to vibration-induced loosening without requiring a separate locking device. At 15\/32 inches high and 1-1\/4 inches across the flats, this nut follows standard UNC thread geometry with right-hand thread direction. It is sold individually and is appropriate for general mechanical assembly work across maintenance, construction, and light fabrication applications.\u003c\/p\u003e\u003cp\u003eThis nut is suited for non-critical fastening applications in residential and commercial construction, equipment maintenance, and general industrial assembly where a UNC 7\/8-9 fastener is required. The zinc plating provides basic corrosion resistance in dry or mildly humid environments. Grade 2 steel is appropriate for standard load-bearing connections that do not require the higher proof load of Grade 5 or Grade 8 hardware. Tradespeople and maintenance technicians use this nut as a replacement or new-installation fastener in structural framing, equipment mounting, and similar field assembly tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking style resists loosening from vibration without adhesives or additional hardware\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction suitable for general-purpose fastening applications\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance in standard service environments\u003c\/li\u003e\n\u003cli\u003eRight-hand UNC thread direction conforms to standard inch-series fastener practice\u003c\/li\u003e\n\u003cli\u003eCompact 15\/32-inch height fits tight clearance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC replacement or new-installation hex lock nut for any 7\/8-9 threaded bolt or stud in general mechanical and structural assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand with a standard 1-1\/4-inch wrench or socket. Drive the nut down until the nylon insert engages the bolt threads, then torque to values appropriate for Grade 2 steel fasteners per applicable project specifications. Nylon insert lock nuts are generally considered single-use; inspect the insert before reuse and replace if the nylon shows wear or deformation. No special tools or trade licenses are required for standard fastener installation.\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: 7\/8-9\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: UNC\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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: 15\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161716\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: B52001658\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710025466162,"sku":"B52001658","price":23.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2bf2eda5e24ef06c4657544d8cec1d0.jpg?v=1788463279","url":"https:\/\/voomisupply.com\/products\/value-collection-b52001658-hex-lock-nut-7-8-9-nylon-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
