Manufactured from alloy steel with a black oxide finish, this fastener measures 2.25 inches in length under the head and features a 5\/8-inch hex drive socket for use with a standard hex key or Allen wrench. The 3\/4-16 UNF thread specification indicates a fine-thread pattern, which provides greater tensile strength and improved resistance to loosening under vibration compared to coarse-thread equivalents. It meets ASME\/ANSI B18.3 and ASTM A574 dimensional and mechanical standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general-purpose and precision mechanical assemblies where a recessed drive is preferred over an exposed bolt head. Common applications include machine components, tooling fixtures, hydraulic equipment, and any assembly requiring a flush or countersunk fastener profile. The fine-thread 3\/4-16 UNF designation makes it appropriate for use in tapped holes requiring tighter thread engagement, particularly in metal-to-metal joints subject to dynamic loads or vibration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF fine-thread pattern for high tensile strength and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e2.25 inches length under head, fully threaded along the entire shank\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive compatible with standard Allen keys and hex drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for elevated mechanical strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style replacement or drop-in fastener for any application specifying a 3\/4-16 UNF hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance mechanics using a calibrated hex key or torque wrench with the appropriate 5\/8-inch hex bit. De-energize, depressurize, or otherwise isolate the assembly before removing or installing fasteners. Thread engagement should be verified against the tapped hole specification before final torque. Do not substitute this fine-thread fastener in applications specifying a coarse-thread UNC pattern without confirming hole compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.25 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: 5\/8 inch\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: 0.05 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: 581726BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709675340082,"sku":"581726BR","price":49.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07621d154946f34f338b91974fa603fc.jpg?v=1788459000","url":"https:\/\/voomisupply.com\/products\/value-collection-581726br-hex-socket-cap-screw-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
