This partially threaded cap screw measures 8 inches in length under the head and accepts a 5\/16-inch hex drive. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. The ASME\/ANSI B18.3 and ASTM A574 standards govern its dimensions and mechanical properties, making it a recognized choice for precision and structural assemblies where tensile strength is critical.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in machinery, tooling fixtures, structural frames, and industrial equipment where a recessed socket head is preferred over an external hex configuration. The socket cap profile allows installation in counterbored holes or tight clearance areas where a wrench cannot reach. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors working in manufacturing, fabrication, and heavy equipment service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC thread size for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head provides extended reach for deep or stacked assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for use with standard Allen or hex key tools\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows shear load transfer through the unthreaded grip zone\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection and a low-glare matte surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 inch-series socket cap screw for use in any 3\/8-16 UNC tapped hole requiring an 8-inch partially threaded fastener with a 5\/16-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/16-inch hex key or Allen driver; use a calibrated torque wrench when a specific clamp load is required for the assembly. Ensure the mating tapped hole is clean and free of debris before driving the fastener to avoid cross-threading. De-energize or lock out any machinery before replacing fasteners on powered equipment in accordance with applicable OSHA lockout\/tagout procedures. Apply thread lubricant or anti-seize only if specified by the equipment manufacturer, as dry torque values and lubricated torque values differ.\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: 8 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\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: 581485PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700235272498,"sku":"581485PR","price":907.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16422a91f8cc28c01cf065c86026f87e.jpg?v=1788387959","url":"https:\/\/voomisupply.com\/products\/value-collection-581485pr-hex-socket-cap-screw-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
