Manufactured from 4037 alloy steel with a yellow cadmium-plated finish, this cap screw offers corrosion resistance and durability in demanding service environments. It features a 5\/16-18 UNC thread, a 1\/4-inch hex drive socket, and a 1-3\/4-inch length under head with partial threading. The screw conforms to ASME B18.3 fastener standards. It is suited for mechanical assembly, maintenance work, and manufacturing applications requiring precision-grade hardware.\u003c\/p\u003e\n\u003cp\u003eThis screw is a fit for industrial, mechanical, and trade assembly applications where a socket-drive cap screw is required. The 5\/16-18 UNC coarse thread pattern is widely used in general mechanical assembly, HVAC equipment mounting, bracket installation, and light structural connections. The partial threading allows for clamping force to be applied across unthreaded shank sections, which is standard practice in through-bolt and clamped-joint assemblies. The yellow cadmium plating provides protection against oxidation in both indoor and moderate outdoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-inch length under head with partial threading for clamped-joint applications\u003c\/li\u003e\n  \u003cli\u003e4037 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eYellow cadmium-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service hex socket cap screw for mechanical assemblies requiring a 5\/16-18 UNC partially threaded alloy steel socket head fastener per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener is installed by mechanics, millwrights, HVAC technicians, and general trade professionals using a 1\/4-inch hex Allen key or compatible socket bit. Always de-energize equipment and relieve any system pressure before accessing fastened assemblies. Verify thread engagement depth and inspect tapped holes for damage before installation. Do not over-torque; refer to applicable engineering specifications or ASME torque guidelines for 5\/16-18 alloy steel fasteners.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 4037\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Yellow Cadmium Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.436 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: MS16997-83\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722833428786,"sku":"MS16997-83","price":188.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5a87df559821747724c65aca9d17329_e906f86a-df07-4090-8efb-dd4286ecba52.jpg?v=1788596609","url":"https:\/\/voomisupply.com\/products\/value-collection-ms16997-83-hex-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
