This screw features a 1\/4-20 UNC thread with an overall length of 1-1\/8 inches and is fully threaded along that length. The 82-degree flat head seats flush with the workpiece surface when installed in a properly chamfered hole. Drive engagement is via a 5\/32-inch hex socket. Constructed from alloy steel with a black oxide finish, it provides moderate corrosion resistance and is suited for interior and protected-environment mechanical assemblies. Licensed tradespeople and machine builders commonly specify this fastener type for compact, low-profile joint designs.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in mechanical, structural, and industrial assembly applications where a flush-mount screw head is required. The 82-degree flat head geometry conforms to ASME\/ANSI B18.3 and ASTM F835 standards, making it appropriate for precision machine components, fixtures, tooling plates, and fabricated steel assemblies. The black oxide finish is typical for indoor or controlled-environment use where minimal surface corrosion protection is acceptable. This size is commonly found in light machinery, brackets, enclosures, and general fabrication work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush when installed in a matching countersunk hole\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for standard Allen key or hex bit installation\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/4-20 UNC along the entire 1-1\/8-inch length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in demanding assemblies\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\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 a standard 1\/4-20 UNC flat socket cap screw for use in any application requiring an ASME\/ANSI B18.3 or ASTM F835 compliant flush-mount fastener in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized 82-degree countersink in the mating material to achieve a flush seating surface. Use a calibrated 5\/32-inch hex key or socket bit driver; do not use an undersized driver, as this risks rounding the socket. De-energize and lock out any equipment before fastener removal or replacement in live assemblies. Apply thread-locking compound or torque to specification per the assembly engineering drawing where vibration or dynamic loading is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/8 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: 5\/32 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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 721142PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51707194081586,"sku":"721142PR","price":4644.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/711a00691ee3bf81700af07d15333421.jpg?v=1788438877","url":"https:\/\/voomisupply.com\/products\/value-collection-721142pr-flat-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
