Manufactured from 18-8 stainless steel with no additional coating, this fastener offers solid corrosion resistance in moderate-exposure environments. The 5\/16-18 UNC thread size and 3\/8-inch length under the head make it well suited for light-duty clamping and assembly work where a standard inch-series unified coarse thread is specified. Installed with a standard hex wrench or socket driver, this screw is a reliable choice for maintenance and fabrication crews working across HVAC, plumbing, electrical, and pool equipment applications.\u003c\/p\u003e\n\u003cp\u003eThis fastener is appropriate for use in residential and commercial service environments where stainless steel is preferred over zinc-plated or plain steel alternatives. Typical applications include panel assembly, equipment mounting, bracket fastening, and general hardware replacement. The fully threaded shank provides maximum thread engagement over the full 3\/8-inch grip length, making it effective for thin-stock assemblies and through-bolt configurations. Trade professionals in HVAC, plumbing, and pool service commonly stock this size for field repairs and equipment installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in moisture-exposed environments\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the entire 3\/8-inch length under head\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard ensures compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no plating that can flake, chip, or introduce galvanic incompatibility with stainless hardware\u003c\/li\u003e\n  \u003cli\u003eHex drive accepts standard 1\/2-inch hex wrenches, sockets, and nut drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC hex head cap screw for use in any application requiring a 5\/16-18 thread and 3\/8-inch length under head in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/2-inch hex wrench, socket, or nut driver. Power down or de-energize any equipment before fastener service. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or saltwater environments without evaluating galvanic compatibility. Do not overtighten — 18-8 stainless fasteners are subject to galling if driven at excessive speed or torque without appropriate lubrication.\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\/8 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\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\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: R57001120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692574114098,"sku":"R57001120","price":4636.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9280c038f9cbf1d1be76ed88bef803c8_09f3bab1-14d9-4696-9683-988ae7ef9e6a.jpg?v=1788299545","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001120-hex-head-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
