It features a right-hand thread and meets the ANSI ASME B18.2.2 fastener standard. The nut measures 15\/16 inches across flats and 35\/64 inches in height, making it a standard-geometry hex nut suited for medium-strength bolted assemblies. With a Rockwell C32 hardness rating, this nut provides reliable clamping force in applications where Grade 5 strength is specified. Plumbers, HVAC technicians, electricians, and general trade professionals use this fastener when assembling or securing equipment, brackets, and mechanical components.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is appropriate for residential and commercial trade applications where a fine-thread 5\/8-18 UNF fastener is required. Common install scenarios include securing HVAC equipment mounting hardware, plumbing fixture assemblies, electrical panel brackets, and general mechanical equipment. The zinc-plated finish provides a basic level of corrosion resistance suitable for indoor and moderately protected environments. It is sold individually with a minimum order quantity of 25 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF right-hand thread for fine-thread bolted connections\u003c\/li\u003e\n  \u003cli\u003eSAE J995 Grade 5 steel construction with Rockwell C32 hardness\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e15\/16 inches across flats for standard hex wrench or socket fitment\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI ASME B18.2.2 fastener dimensional standard\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 25 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-geometry replacement or stocking hex nut for any 5\/8-18 UNF fine-thread bolt or threaded stud where SAE J995 Grade 5 strength and ANSI ASME B18.2.2 dimensional compliance are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by any trade professional working with 5\/8-18 UNF threaded fasteners. Use a 15\/16-inch open-end wrench, box wrench, or socket to drive the nut. De-energize or shut off any systems before working on fastened assemblies to prevent movement or contact with live components. Do not mix Grade 5 nuts with higher-grade hardware in critical structural joints without verifying compatibility with the applicable mechanical or structural code.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: SAE J995 Grade 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: Rockwell C32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 15\/16 inches (0.9375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Points\u003c\/strong\u003e: 1.083 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 35\/64 inches (0.5469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.062 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI ASME B18.2.2\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: MP31217\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691021599026,"sku":"MP31217","price":28.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bc2f55fb111d0d8b97cd0b633d2a875.jpg?v=1788279377","url":"https:\/\/voomisupply.com\/products\/value-collection-mp31217-hex-nut-5-8-18-grade-5-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
