It features an 82-degree flat head and a 1\/16-inch hex socket drive, accepting a standard hex key for installation and removal. The screw is sized 4-40 with a 3\/8-inch overall length and is fully threaded along its entire shank. Constructed from alloy steel with a black oxide finish, it provides solid mechanical strength and moderate corrosion resistance in indoor or protected environments. This fastener follows ASME\/ANSI B18.3 and ASTM F835 standards. It is suited for precision assemblies, machine components, and enclosures where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light mechanical assemblies, electronics enclosures, jigs, fixtures, and equipment panels where a countersunk socket-drive fastener is needed. The 4-40 UNC thread size is common in instrument-grade and small-machine applications. The fully threaded shank allows engagement along the complete fastener length, which is particularly useful in thin-material applications. Machinists, millwrights, and maintenance technicians typically install this type of fastener in production and repair settings.\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\u003e1\/16-inch hex socket drive for standard hex key use\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread with fully threaded shank for maximum engagement\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for surface protection in low-moisture environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for any assembly requiring a 4-40 UNC fully threaded flat socket cap screw with an 82-degree head angle and 1\/16-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/16-inch hex key or appropriate bit driver. Ensure the mating counterbore or countersink is machined to match the 82-degree head angle before installation. De-energize and lock out any equipment before replacing fasteners in live assemblies. Avoid over-torquing small-diameter screws, as alloy steel fasteners at this thread size have limited torque capacity.\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\u003eLength\u003c\/strong\u003e: 3\/8 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 0.00109 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: 211018P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694526890290,"sku":"211018P","price":2169.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa555a831e155cca1234a37facb96d9a.jpg?v=1788325080","url":"https:\/\/voomisupply.com\/products\/value-collection-211018p-flat-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
