The 82-degree flat head seats flush with or below the mating surface, eliminating protrusions that could interfere with moving parts or mating components. Driven by a 1\/4-inch hex socket, it delivers high torque transfer in tight spaces. The screw measures 7\/16-14 UNC thread by 4 inches overall length and is partially threaded to ensure proper clamping force when joining thick material stacks. Made from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance for interior and protected environments. Licensed machinists, millwrights, and maintenance mechanics typically install this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw suits light industrial, OEM machinery, tooling fixtures, and general mechanical assembly where a low-profile fastener head is required. The 7\/16-14 UNC thread pitch is a widely used coarse-thread standard in inch-system mechanical applications. Partial threading is appropriate for joints where the unthreaded shank bridges the interface between two clamped members, maintaining clamp load without thread engagement in both parts. Black oxide finish is suitable for interior applications and oiled or greased environments where mild corrosion protection is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head for flush or countersunk installation without surface protrusion\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for high-torque engagement in confined areas\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers moderate corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports proper clamping in thick-material joints\u003c\/li\u003e\n  \u003cli\u003eConforms to 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 and general-use replacement flat socket cap screw for inch-system mechanical assemblies requiring a 7\/16-14 UNC thread and a countersunk 82-degree flat head seating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified maintenance personnel. The mating countersink should be machined to an 82-degree included angle to match the head geometry before installation. De-energize or lock out all equipment per OSHA LOTO procedures before servicing any fastened assembly. Use a properly sized 1\/4-inch hex key or socket driver to avoid rounding the drive recess.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 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\/4 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\u003eThread Standard\u003c\/strong\u003e: UNC\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: 721404PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710755471666,"sku":"721404PR","price":2955.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_d2a195fd-5652-40e6-b56f-445a52ead98c.jpg?v=1788470247","url":"https:\/\/voomisupply.com\/products\/value-collection-721404pr-flat-socket-cap-screw-7-16-14","provider":"Voomi Supply","version":"1.0","type":"link"}
