Manufactured from 18-8 stainless steel, this screw offers solid corrosion resistance suitable for general industrial, marine-adjacent, and food-service-adjacent environments. The 82-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. Drive engagement is via a 3\/8-inch hex socket. Thread size is 5\/16-18 UNC with an overall length of 1.5 inches. This fastener is handled by machinists, millwrights, maintenance technicians, and mechanical contractors working with inch-standard hardware.\u003c\/p\u003e\n\u003cp\u003eThe 243508 is suited for applications requiring a countersunk fastener in ferrous and non-ferrous assemblies, equipment frames, brackets, panels, and fixtures where thread size 5\/16-18 UNC is specified. The 18-8 stainless steel construction makes it a practical choice in mildly corrosive or wet environments. This item is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for stocking, kitting, or production assembly use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex socket drive for reliable torque transfer\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC thread standard — inch-system compatible\u003c\/li\u003e\n  \u003cli\u003e1.5-inch overall length for moderate-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 pieces — suitable for production and stocking use\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 specifying a 5\/16-18 UNC thread, 82-degree countersunk flat head, and 1.5-inch overall length in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a countersunk hole machined to an 82-degree included angle to achieve a proper flush seat. Use a correctly sized hex key or socket driver — a 3\/8-inch hex drive is required. Apply appropriate torque per the assembly specification for 5\/16-18 stainless steel fasteners; avoid overtorquing, which can gall stainless threads. Anti-seize compound is recommended when mating stainless fasteners to stainless tapped holes to prevent galling.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 243508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689160868146,"sku":"243508","price":7523.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abafd7ab574ef56f3c4e75db4a1cda65.jpg?v=1788255378","url":"https:\/\/voomisupply.com\/products\/value-collection-243508-flat-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
