It features a 3\/8-16 UNC thread size with a 4.5-inch length under the head and a 5\/16-inch hex drive socket. The fastener is made from alloy steel with a black oxide coating that provides mild corrosion resistance and reduces light reflection. It is partially threaded, which allows for improved clamping force in through-bolt applications. Machinists, maintenance technicians, and industrial assemblers install this type of fastener where torque requirements exceed what standard steel screws can handle.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for use in machine frames, jigs, fixtures, hydraulic components, and general industrial assemblies where a recessed hex drive is preferred over an external hex head. The partially threaded shank makes it well-suited for applications requiring a bearing surface or where precise hole alignment is needed. It meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for demanding mechanical and structural fastening tasks across manufacturing and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for strong, standard-pitch engagement in imperial-threaded assemblies\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length under head provides reach for thick material stacks or deep-clearance applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive allows high torque input with a standard hex key or socket driver\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction delivers tensile strength above standard carbon steel fasteners\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild rust resistance and a low-glare appearance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance and clamping in bolted joints\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 dimensional and mechanical standards\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 industrial machinery, machine tool fixtures, and mechanical assemblies requiring a 3\/8-16 UNC partially threaded socket head fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 5\/16-inch hex key or T-handle driver. Ensure the mating threaded hole or nut is clean and free of debris before driving the fastener. Do not exceed the rated torque for 3\/8-16 alloy steel socket cap screws as specified in applicable ASME or equipment manufacturer guidelines. Apply a thread lubricant or anti-seize compound only when specified by the assembly procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 inches\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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 015279PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691281908018,"sku":"015279PR","price":907.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1887c5e553c059338fd1a1d034074007.jpg?v=1788282659","url":"https:\/\/voomisupply.com\/products\/value-collection-015279pr-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
