It measures 2.5 inches under the head with a Unified National Coarse (UNC) thread form. The 1\/2-inch hex drive accepts a standard hex wrench or socket. The 18-8 stainless steel construction provides solid corrosion resistance for indoor and outdoor assemblies without the cost of higher-alloy grades. This fastener is sold in a minimum order quantity of 50 pieces, making it a practical choice for contractors, maintenance techs, and service professionals who need consistent hardware on hand for recurring jobs.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for general mechanical and structural assembly across trade applications including HVAC equipment mounting, electrical panel and enclosure work, plumbing fixture attachment, and pool equipment installation. The UNC thread form is the most common inch-series fastener standard in North American equipment, so this screw fits readily into tapped holes and standard hex nuts across a broad range of assemblies. The stainless grade makes it appropriate for humid or corrosive environments where carbon steel fasteners would oxidize.\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 is compatible with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head provides grip for deeper assemblies and stacked material\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive works with common wrenches and sockets already in a service kit\u003c\/li\u003e\n  \u003cli\u003eSold in multiples of 50 to keep fastener stock consistent across repeat service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any assembly requiring a 5\/16-18 UNC threaded fastener in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation does not require a licensed trade credential but is commonly performed by HVAC technicians, electricians, plumbers, and general maintenance staff. Verify thread engagement depth before fastening to ensure full load-bearing contact. Do not mix stainless steel fasteners with dissimilar metals in submerged or highly conductive environments without considering galvanic compatibility. Apply fastener torque consistent with published UNC stainless steel torque guidelines for the fastener diameter.\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: 2.5 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\u003eHex Key Size\u003c\/strong\u003e: 1\/2 inch\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 piece per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 209058B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701611790642,"sku":"209058B","price":118.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d307cc96f3a594b1520a916501c4eed.jpg?v=1788402457","url":"https:\/\/voomisupply.com\/products\/value-collection-209058b-hex-head-cap-screw-5-16-18-x-2-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
