Manufactured from alloy steel with a black oxide finish, this fastener meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards for dimensional accuracy and mechanical performance. The 3\/8-16 UNC thread size and 3-1\/4 inch length under head make it suitable for medium-to-heavy clamping loads. The 5\/16 inch hex drive socket interface provides positive torque transfer with standard hex keys or socket drivers. This screw is used by machinists, millwrights, pipefitters, and general mechanical trade professionals.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in industrial machinery, HVAC equipment frames, structural brackets, and mechanical assemblies that require a recessed-drive fastener with a clean seating surface. Partial threading allows the unthreaded shank to act as a locating or shoulder feature in close-tolerance bores, making it a practical choice for precision fixture work and equipment mounting where alignment matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 inch length under head for medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for shear-load resistance and precision alignment\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance in dry or lightly oiled environments\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch hex socket drive for use with standard Allen keys or hex socket tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any 3\/8-16 UNC tapped hole requiring a recessed-drive fastener with a 3-1\/4 inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance technicians, or mechanical tradespeople using a 5\/16 inch hex key or socket driver. Ensure the tapped hole is clean and free of debris before threading the fastener. Do not exceed the design torque rating for the fastener grade and thread size as specified in applicable ASME or IFI fastener standards. Black oxide finish is not a heavy corrosion barrier — apply a thread lubricant or anti-seize compound if fasteners will be exposed to moisture or dissimilar metals.\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: 3-1\/4 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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.46 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: 015273PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710628495666,"sku":"015273PR","price":2458.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f1a7bd4726da7616a455d5263f833d9.jpg?v=1788468889","url":"https:\/\/voomisupply.com\/products\/value-collection-015273pr-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
