Manufactured from 18-8 stainless steel, this fastener offers reliable corrosion resistance in wet, outdoor, and chemically exposed environments. The screw features a 5\/16-18 UNC thread and a 2.5-inch length under head, making it suitable for medium-duty clamping and assembly tasks. Machinists, millwrights, pipefitters, and general maintenance trades rely on hex cap screws like this for reliable, repeatable fastening with standard hex-drive tooling.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in residential and commercial mechanical systems, equipment mounting, pipe support hardware, enclosure assembly, and structural connections where corrosion resistance is a priority. The 18-8 stainless steel grade is commonly specified in HVAC equipment mounting, plumbing support brackets, pool equipment installations, and marine-adjacent environments. Full threading along the shank provides consistent thread engagement across varying material thicknesses and eliminates the need for a clearance hole in thinner stock applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows maximum thread engagement in any material thickness\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard ensures compatibility with standard nuts, inserts, and tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eHex drive head accepts standard hex wrenches and sockets for high-torque installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC inch-series hex head cap screw compatible with any 5\/16-18 tapped hole, nut, or threaded insert per ASME B18.2.1 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a standard hex wrench, box-end wrench, or socket driver sized for a 1\/2-inch hex head. Ensure mating tapped holes or nuts are clean and free of debris before installation. In stainless steel fastener applications, apply anti-seize compound to prevent thread galling, which is a known risk with 18-8 stainless against stainless mating threads. Follow applicable equipment manufacturer torque guidelines for the joint material and thread size.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 10\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: 207843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693342294322,"sku":"207843","price":1976.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26362c611916d2c8047907c34d76f52f.jpg?v=1788310936","url":"https:\/\/voomisupply.com\/products\/value-collection-207843-hex-head-cap-screw-5-16-18-x-2-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
