It features a 4-40 UNC thread, an overall length of 3\/8 inches, and is manufactured from 316 stainless steel for strong corrosion resistance in wet, chemical, or marine environments. The 82-degree flat head seats flush with the work surface when installed in a properly countersunk hole. Drive engagement is via a 5\/32-inch hex socket, which provides controlled torque application with standard hex key tooling. Machinists, maintenance technicians, and assemblers working on precision equipment, instrumentation, or marine hardware commonly install this screw.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for applications where a low-profile or flush fastener is required and clearance above the surface is limited. The 316 stainless steel grade offers superior resistance to chlorides and oxidizing acids compared to 304 grade, making it appropriate for food processing, pharmaceutical, and coastal or offshore environments. Its small 4-40 thread size is common in instrumentation panels, electronic enclosures, and light mechanical assemblies. This item is sold individually, with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction provides elevated corrosion resistance in harsh or wet environments\u003c\/li\u003e\n  \u003cli\u003e82-degree flat head profile allows flush installation in countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for precise torque control with standard hex key tooling\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard ensures compatibility with common inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3\/8 inches suits thin-profile and compact assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series flat socket cap screw for use in any application requiring a 4-40 UNC threaded, countersunk fastener with an 82-degree flat head seating angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a properly countersunk hole machined to match the 82-degree head angle to achieve a flush seating surface. Use a calibrated hex key or hex driver of the correct 5\/32-inch size to avoid rounding the socket drive. Avoid over-torquing small-diameter screws, as 4-40 fasteners have limited tensile capacity. Verify thread engagement depth meets minimum requirements for the base material before final assembly.\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\u003eOverall Length\u003c\/strong\u003e: 3\/8 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: 5\/32 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: 316\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: 063018PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698571346226,"sku":"063018PS","price":746.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b66e1b6266c1ea2d4d625a238a7a707_a8b0c88d-0677-46c0-990f-cf6f4a5bc783.jpg?v=1788364851","url":"https:\/\/voomisupply.com\/products\/value-collection-063018ps-flat-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
