It features a 5\/16-18 UNC thread and measures 3\/4 inches in length under the head, with full threading along the entire shank. Driven by a 1\/4-inch hex key, it seats flush and tight in counterbored holes. Manufactured from 4037 alloy steel with a yellow cadmium-plated finish, this screw delivers solid mechanical strength along with corrosion resistance suitable for demanding service environments. It conforms to ASME B18.3 fastener standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial machinery, tooling fixtures, equipment panels, and general mechanical assemblies where a recessed drive head is required. The fully threaded shank provides maximum thread engagement across the full clamped length, making it a reliable choice in applications where vibration resistance and consistent clamp load are priorities. Maintenance technicians, machinists, and mechanical assemblers commonly install this type of fastener across a wide range of light to medium-duty applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length under head with full threading along the entire shank\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for precise torque application using a hex key or Allen driver\u003c\/li\u003e\n  \u003cli\u003e4037 alloy steel construction for enhanced tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eYellow cadmium-plated finish provides corrosion and oxidation 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 maintenance fastener for mechanical assemblies requiring a 5\/16-18 UNC hex socket cap screw per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench with a 1\/4-inch hex bit to reach the manufacturer-specified torque for the mating assembly. Ensure the tapped hole is clean and free of debris before threading. De-energize and lock out any equipment before replacing fasteners in live assemblies. Cadmium-plated fasteners should be handled in accordance with applicable safety guidelines due to the hazardous nature of cadmium compounds.\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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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 inches\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 Coating\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: 0.24 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: MS16997-78\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698874188082,"sku":"MS16997-78","price":80.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5a87df559821747724c65aca9d17329_f75d9a0a-30ce-4ad6-8887-8faa6e58254c.jpg?v=1788369226","url":"https:\/\/voomisupply.com\/products\/value-collection-ms16997-78-hex-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
