Sized at 4-40 UNC thread by 5\/16 inches overall length, it features an 82-degree flat head and a 1\/16-inch hex socket drive. Constructed from 18-8 stainless steel, this screw offers solid corrosion resistance for both indoor and outdoor environments. It is well suited for machine assembly, instrument panels, and light structural connections where a low-profile head is required and standard hex or Phillips drive access is limited.\u003c\/p\u003e\n\u003cp\u003eThis screw is a common fastener in precision mechanical assemblies, electronics enclosures, and light fabrication work. The 4-40 UNC thread size is frequently used in instrumentation, small appliances, and HVAC controls. Installers and machinists working in corrosive or high-humidity environments benefit from the 18-8 stainless steel construction, which resists rust and staining without the need for additional coatings or platings. The hex socket drive allows torque application in tight clearance situations where a wrench or open-driver cannot reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes for a low-profile finish\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch hex socket drive for use with a standard Allen key or hex bit\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard ensures compatibility with standard tapped holes in that size\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch overall length suits thin panel and light structural fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for applications using 4-40 UNC countersunk hex socket cap screws in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, assemblers, or service technicians using a 1\/16-inch hex key or compatible bit driver. Ensure the receiving hole is properly countersunk to 82 degrees before installation to achieve a flush seating surface. Do not overtighten small-diameter fasteners such as 4-40 screws, as thread stripping is a common failure mode. De-energize any equipment and follow applicable safety lockout procedures before performing fastener work on live assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\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: 5\/16 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\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\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: R63008326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722480255282,"sku":"R63008326","price":443.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/724bf29244c9e836ce8a0ee328f9c544.jpg?v=1788591750","url":"https:\/\/voomisupply.com\/products\/value-collection-r63008326-flat-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
