Manufactured from alloy steel and finished with a black oxide coating, this fastener delivers solid tensile strength and moderate corrosion resistance in a compact, low-profile head form. It is partially threaded, following ASME\/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, maintenance technicians, and mechanical contractors reach for socket cap screws when torque requirements are high and clearance for a wrench is limited.\u003c\/p\u003e\n\u003cp\u003eThis screw is well-suited for machine assembly, fixture building, jig fabrication, and general industrial maintenance where a flush or recessed fastener head is required. The 3\/8-16 UNC coarse thread pattern seats quickly and holds reliably in steel and iron tapped holes. The 9-inch length under head covers deep-reach applications where standard shorter fasteners fall short. The black oxide finish provides mild oil-retention properties that can extend service life in indoor or light-duty environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread for fast engagement in steel and iron tapped bores\u003c\/li\u003e\n  \u003cli\u003e9-inch length under head for deep-reach clamping applications\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a shoulder bearing surface under load\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating offers mild corrosion resistance and reduces light glare in equipment\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 compatible with any 3\/8-16 UNC tapped hole requiring a 5\/16-inch hex drive fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove with a 5\/16-inch hex key or hex socket bit rated for the expected torque load. De-energize and lock out any equipment before servicing fastened assemblies. Inspect tapped holes for thread damage or contamination before installation. Apply thread lubricant or anti-seize compound as appropriate for the service environment to prevent galling and aid future removal.\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: 9 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 inch\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\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: 581487PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718801195314,"sku":"581487PR","price":1934.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73c141c46489b74db3e416ee7a07743a.jpg?v=1788555650","url":"https:\/\/voomisupply.com\/products\/value-collection-581487pr-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
