Manufactured from 18-8 stainless steel, this fastener offers solid corrosion resistance for general-purpose and light industrial applications. The socket cap head style allows installation in tight clearances where a standard hex bolt head would not fit. Machinists, assembly technicians, and maintenance professionals use this screw when a clean, low-profile fastener with reliable thread engagement is required. Its 4-40 UNC thread form is a common fine-pitch unified coarse designation frequently found in instrument panels, brackets, and light mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in panel assembly, instrument enclosures, electronic chassis, and light structural brackets where stainless steel is specified for corrosion resistance or sanitary requirements. The 4-40 UNC thread is widely used in small-format mechanical and electrical assemblies found in both commercial and residential equipment. Installation is straightforward with a standard 3\/32-inch hex key or Allen driver. This part is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock, maintenance kits, or production line inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread for precise engagement in small-format assemblies\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch length under head suits moderate-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e3\/32-inch internal hex drive accepts standard Allen keys and hex drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eSocket cap head profile allows use in recessed or clearance-limited spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw suitable for use in instrument panels, electronic enclosures, light mechanical assemblies, and any application calling for an 18-8 stainless steel socket cap fastener with a 5\/8-inch under-head length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/32-inch hex key or Allen-style driver. Ensure the mating threaded hole or nut is clean and properly tapped to 4-40 UNC specification before driving. Avoid cross-threading by starting the screw by hand before applying torque. When used in stainless-to-stainless assemblies, apply an anti-galling compound to the threads to prevent seizing during tightening.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket (Allen)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/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: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: R40664460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714236088626,"sku":"R40664460","price":474.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5028069f87728adee322fbc6aa15a65.jpg?v=1788498035","url":"https:\/\/voomisupply.com\/products\/value-collection-r40664460-hex-socket-cap-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
