It features an 82-degree flat head profile driven by a 1\/2-inch hex socket, allowing the head to sit flush with or below the surface of the mating material. The screw measures 3\/4-16 UNF thread by 1-1\/4 inches in overall length and is fully threaded along its entire shank. Machined from alloy steel with a black oxide finish, it is suited for use where moderate corrosion resistance and a low-profile head are required. Licensed trades and industrial maintenance technicians commonly install this fastener in precision machinery, jigs, fixtures, and structural assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is intended for general industrial and mechanical fastening applications where a countersunk head is necessary to avoid surface protrusion. The 3\/4-16 UNF thread is a fine-pitch unified thread, making it appropriate for applications requiring precise clamping force control or use in thinner-walled components where coarse threads would not engage adequately. It conforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards, which govern dimensions, mechanical properties, and testing for socket cap screws in inch series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush or countersunk installation\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex socket drive for use with standard hex keys or bit drivers\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNF fully threaded shank, 1-1\/4 inches overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for any application requiring a 3\/4-16 UNF flat socket cap screw with an 82-degree head angle and a 1\/2-inch hex socket drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener is typically installed by machinists, millwrights, or mechanical maintenance technicians using a calibrated torque wrench and an appropriate 1\/2-inch hex key or socket bit. Ensure the mating countersink is machined to an 82-degree included angle for proper head seating. Degrease threads and apply thread lubricant or specified thread-locking compound as required by the assembly specification before torquing. Follow applicable industry torque guidelines for alloy steel UNF fasteners at this diameter.\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\u003eOverall Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-degree Flat\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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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 F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 721405BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696560210226,"sku":"721405BR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_f3595384-05af-4465-9cff-efd88e3ec243.jpg?v=1788343959","url":"https:\/\/voomisupply.com\/products\/value-collection-721405br-flat-socket-cap-screw-3-4-16","provider":"Voomi Supply","version":"1.0","type":"link"}
