The flat head seats fully into a countersunk hole, leaving a smooth surface when installed. The hex socket drive accepts a 5\/64-inch hex key for installation and removal. Made from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in controlled environments. The thread is 6-40 UNF, fully threaded along a 1\/4-inch overall length. Machinists, assembly technicians, and maintenance professionals install this type of fastener across a range of light mechanical and industrial applications.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is suited for precision assemblies where a low-profile or flush-mount fastener is required. The 6-40 UNF thread specification is common in fine-thread applications where greater thread engagement per inch is needed compared to UNC alternatives. The fully threaded shank provides maximum thread engagement across the full 1\/4-inch length. Typical use cases include instrument housings, small mechanical assemblies, jigs, fixtures, and equipment panels where surface clearance is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat head design allows flush or countersunk installation for a smooth finished surface\u003c\/li\u003e\n\u003cli\u003e5\/64-inch hex socket drive for precise torque application with a standard hex key\u003c\/li\u003e\n\u003cli\u003e6-40 UNF fully threaded for maximum thread engagement in the 1\/4-inch length\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile strength for a fastener of this size class\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces light reflection and offers mild corrosion resistance in dry environments\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNF flat socket cap screw compatible with any 6-40-tapped hole requiring a countersunk or flush-mount fastener per ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or assembly technician should verify that the mating tapped hole is cut to 6-40 UNF specification before installation. Use the correct 5\/64-inch hex key to avoid rounding the drive socket. Ensure the countersink angle in the receiving material matches the screw head angle to achieve full seating. Do not exceed the rated torque range for the fastener size and material as defined by applicable ASME standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/4 inches (overall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 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: 5\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 721074PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698862948658,"sku":"721074PR","price":5508.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_0e1e31f8-e0ec-47c7-998e-14a2f9977aaa.jpg?v=1788369044","url":"https:\/\/voomisupply.com\/products\/value-collection-721074pr-flat-socket-cap-screw-6-40","provider":"Voomi Supply","version":"1.0","type":"link"}
