It features a 1\/4-20 UNC thread and measures 2.5 inches in overall length. The 82-degree flat head sits flush with or below the mating surface, eliminating protrusions in finished assemblies. Drive engagement is through a 5\/32-inch hex socket. Constructed from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance for industrial and mechanical installations. Threading is partial, leaving a smooth shank section near the head for shear-load applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machine assemblies, fixtures, tooling, and structural components where a flush-mount fastener is required. The 1\/4-20 UNC thread is a common standard size found across general industrial, manufacturing, and maintenance environments. It is typically installed by machinists, maintenance technicians, and mechanical contractors. The black oxide finish makes it a practical choice for interior or low-moisture applications where appearance and mild rust resistance are both considerations.\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\u003e5\/32-inch hex socket drive for standard Allen key or hex bit engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread on a 2.5-inch overall length\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows shank to carry shear loads\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for low-reflectance appearance and mild corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use fastener compatible with any 1\/4-20 UNC threaded hole requiring an 82-degree countersunk flat head and a 2.5-inch grip range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly countersunk 82-degree seat to achieve correct head seating and clamp load. Use a calibrated 5\/32-inch hex key or bit driver to torque the fastener; do not use worn or undersized drivers that may strip the socket. Ensure the receiving thread is clean and free of debris before installation. Power down or de-energize any equipment before accessing fastener locations in live mechanical or electrical assemblies.\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: 2.5 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: 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\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: 0.05 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: 721146PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715756359986,"sku":"721146PR","price":1240.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d42e0e73b56378cad7caade45a41b4b1.jpg?v=1788518017","url":"https:\/\/voomisupply.com\/products\/value-collection-721146pr-flat-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
