It features an 82-degree flat head with a 3\/8-inch hex socket drive, accepting a standard hex key for installation. The fastener is machined from 18-8 stainless steel, providing corrosion resistance suitable for general industrial, marine-adjacent, and outdoor service environments. The thread is 5\/16-18 UNC, and the overall length is 1-1\/4 inches. This screw is commonly installed by millwrights, maintenance technicians, and general tradespeople working with metal fabrications, fixtures, and equipment assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw suits applications where a protruding head would interfere with mating surfaces, moving parts, or aesthetic requirements. The 82-degree countersink angle is compatible with standard countersunk hole geometry used in inch-system metalworking. Typical install scenarios include machine frames, brackets, panels, and structural assemblies where a flush finish is required. The 5\/16-18 UNC thread engages standard tapped holes in steel, aluminum, and similar substrates across residential, commercial, and light industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for torque application with a standard hex key or hex bit\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction offers corrosion resistance in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread for compatibility with standard inch-system tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-inch overall length suits moderate fastening depth requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system flat socket cap screw for use in any application requiring a 5\/16-18 UNC threaded fastener with an 82-degree countersunk flat head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/8-inch hex key or hex bit driver. Ensure the mating hole is properly countersunk to 82 degrees to achieve full head seating and flush surface contact. Verify thread engagement depth is adequate for the load before final tightening. Stainless fasteners can be prone to galling — apply anti-seize compound when threading into stainless tapped holes to prevent thread seizure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/4 inches\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: 3\/8 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\u003eThread Standard\u003c\/strong\u003e: UNC\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: 0.01 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: MP63869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715080945970,"sku":"MP63869","price":30.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/deeb8ca590615051adbd7fb6aaf8211b.jpg?v=1788509535","url":"https:\/\/voomisupply.com\/products\/value-collection-mp63869-flat-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
