It features a Unified National Coarse (UNC) thread form with a 3-inch length measured under the head and a 1\/2-inch hex drive. Grade 316 stainless steel provides superior corrosion resistance compared to Grade 304, making this fastener well-suited for environments exposed to moisture, chemicals, or salt. It is installed using a standard hex wrench or socket drive and is a common choice for mechanical assemblies requiring durable, corrosion-resistant fastening.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used in a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture assembly, pool and water treatment equipment, and marine or outdoor structural connections. The Grade 316 alloy is particularly appropriate in coastal environments, chemical processing areas, and any setting where chloride exposure is a concern. Suitable for both field installation and shop fabrication requiring reliable inch-series fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for high corrosion resistance in wet and chemical environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head provides adequate grip for thick assemblies and stacked components\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex drive accepts standard sockets and wrenches\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for use with standard US fastener hardware\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 compatible with any 5\/16-18 UNC tapped hole or matching hex nut in residential, commercial, or industrial mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2-inch socket, wrench, or hex driver. Ensure mating threads are clean and free of debris before installation. When used in dissimilar metal assemblies, consider appropriate anti-galling compound or isolating washers to prevent galvanic corrosion. Follow applicable mechanical or structural codes for the specific application and torque to values appropriate for 5\/16-18 stainless steel fasteners per your project specifications.\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1\/2 inches\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: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: R63036640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692903203122,"sku":"R63036640","price":2297.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f36bcd456f8cef1c6a1af3d94557fee4.jpg?v=1788304741","url":"https:\/\/voomisupply.com\/products\/value-collection-r63036640-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
