It features an 82-degree flat head profile with a 5\/32-inch hex socket drive and is fully threaded along its 7\/8-inch overall length. The 1\/4-20 UNC thread pattern is a widely used coarse-thread standard. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid mechanical strength and moderate corrosion resistance in indoor or protected environments. It is typically installed by machinists, millwrights, and maintenance technicians using a standard hex key or Allen wrench.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in panel mounting, equipment enclosures, jig and fixture fabrication, and general mechanical assembly where a low-profile flush head is required. The black oxide finish reduces light reflection and provides a degree of surface protection against oxidation. The fully threaded shank maximizes thread engagement across the full fastened length, which is particularly useful in thin material applications or short blind holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush or countersunk seating in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eFully threaded 7\/8-inch overall length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread for broad tooling and hardware compatibility\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 provides mild corrosion resistance and a low-reflectance appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 82-degree countersunk holes sized for 1\/4-20 UNC flat socket cap screws per ASME\/ANSI B18.3.

Verify that tapped hole thread engagement meets applicable mechanical design requirements before torquing. Black oxide finish does not provide significant outdoor corrosion protection — apply supplemental coating or lubricant if exposed to moisture. Follow applicable machine design codes and torque guidelines for 1\/4-20 alloy steel fasteners based on joint requirements.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7\/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\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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: A997091\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716537745714,"sku":"A997091","price":23.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93cebaf39db0921f397b27405de278fa.jpg?v=1788527518","url":"https:\/\/voomisupply.com\/products\/value-collection-a997091-flat-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
