It features a 3\/4-16 UNF thread — a fine-pitch unified thread that provides strong clamping force and resistance to vibration loosening. The screw measures 5 inches in length under the head and is partially threaded, which centers load on the unthreaded shank for improved shear resistance. Made from alloy steel with a black oxide finish, it is suited for interior and low-moisture environments where corrosion resistance demands are moderate. A 5\/8-inch hex drive socket is required for installation.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is commonly used in manufacturing, machining, and maintenance environments. Typical applications include securing machine components, press fixtures, jigs, and structural brackets where a recessed drive head and high tensile strength are required. The partial threading is well suited to through-bolt applications where the shank must bridge a clearance hole without thread engagement in that zone. Installers in industrial maintenance, millwright, and mechanical trades are the primary users of this fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF fine-pitch thread for strong clamping and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e5 inches of length under the head with partial threading for shear-load applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 and ASTM A574 compliant hex socket cap screw suitable for 3\/4-16 UNF threaded bores in industrial machinery, fixtures, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and a properly sized 5\/8-inch hex drive tool. Ensure the threaded bore is clean and free of debris before driving the fastener. Do not over-tighten; consult the applicable engineering specification or assembly drawing for torque requirements specific to your application. Black oxide finish does not provide significant corrosion protection in wet or outdoor environments — apply thread lubricant or anti-seize as dictated by your maintenance standard.\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: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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 inches\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 and 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: 581742BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697050976562,"sku":"581742BR","price":22.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93b7cd707665d26e8683959d8d3c02ca.jpg?v=1788348812","url":"https:\/\/voomisupply.com\/products\/value-collection-581742br-hex-socket-cap-screw-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
