It features a 1\/2-inch length under the head and a Unified National Coarse (UNC) thread form. The 18-8 stainless steel construction provides solid corrosion resistance, making this fastener suited for wet, humid, or chemically active environments where standard carbon steel hardware would degrade. Licensed trade professionals and maintenance technicians rely on this screw for mechanical assemblies, panel mounting, and equipment hardware across HVAC, plumbing, and general industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of residential and commercial trade applications. Common install scenarios include securing equipment brackets, access panels, junction boxes, and sheet metal assemblies. The UNC thread form is the standard in inch-system fastener applications throughout North American mechanical and electrical trades, making this screw a direct fit for most standard tapped holes in that thread size. It is sold individually but requires a minimum order quantity of 100 pieces, making it appropriate for stocking or job-lot purchasing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor service environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread form matches standard inch-system tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch length under head suits shallow-clearance fastening applications\u003c\/li\u003e\n  \u003cli\u003eHex drive head compatible with standard hex wrenches and socket sets\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for direct compatibility with North American hardware standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system hex head cap screw for use in any application requiring a 5\/16-18 UNC threaded fastener with a 1\/2-inch grip length in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by any qualified mechanic or trade technician using a standard hex wrench or socket driver sized for a 5\/16-inch hex head cap screw. Ensure the mating tapped hole is clean and free of debris before threading. Do not overtorque stainless steel fasteners, as the material is susceptible to galling under excessive load. Follow applicable mechanical or structural codes for the specific assembly being fastened.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 207821B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691515576626,"sku":"207821B","price":5717.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8be80ae758beb0b38c9ad893a566177c.jpg?v=1788286341","url":"https:\/\/voomisupply.com\/products\/value-collection-207821b-hex-head-cap-screw-5-16-18-x-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
