It features an 82-degree flat head with a 1\/2-inch hex socket drive, accepting a standard hex key for installation and removal. The screw measures 3-1\/2 inches in overall length and is partially threaded with a 3\/4-16 UNF thread form. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid mechanical strength and moderate corrosion resistance in interior or controlled-environment assemblies. Machinists, millwrights, and maintenance technicians working with structural or mechanical assemblies are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw suits applications where the fastener head must sit flush with or below the mating surface. Common uses include machine frames, jigs, fixtures, tooling plates, and mechanical assemblies where a protruding head would interfere with moving parts or mating components. The 3\/4-16 UNF thread provides finer thread engagement compared to UNC, making it well suited for applications requiring precise clamping force or where vibration resistance is a consideration.

Before installing, verify the mating countersink angle matches the 82-degree head geometry to ensure proper seating and load distribution. Apply appropriate thread lubricant or thread-locking compound per assembly specifications. Alloy steel fasteners are susceptible to corrosion in wet or outdoor environments; select a finish appropriate for the service conditions.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3-1\/2 inches (overall)\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: Partially 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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 721420BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718081577266,"sku":"721420BR","price":29.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_63bfbd0a-58ce-43d8-8d8b-5a26212de5ea.jpg?v=1788549323","url":"https:\/\/voomisupply.com\/products\/value-collection-721420br-flat-socket-cap-screw-3-4-16","provider":"Voomi Supply","version":"1.0","type":"link"}
