Sized at 4-40 UNC thread with a 3\/32 inch hex drive and 1\/8 inch length under head, this screw is manufactured from 18-8 stainless steel, providing corrosion resistance suitable for environments where moisture or mild chemicals are present. The socket drive design allows installation with a hex key or Allen wrench in tight clearance areas where a standard slotted or Phillips driver cannot reach. Electricians, HVAC technicians, plumbers, and general tradespeople use cap screws of this type when assembling or securing panels, brackets, and light-duty mechanical components.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for light mechanical assemblies, instrumentation mounting, panel attachment, and precision equipment applications across residential and commercial trade work. The 4-40 UNC thread designation indicates a fine, controlled thread pitch appropriate for thin metal stock and tapped holes where thread engagement depth is limited. This screw ships individually but carries a minimum order quantity of 100 pieces, making it appropriate for bulk fastener stock or ongoing service kit replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread size for fine-pitch fastening in metal and tapped assemblies\u003c\/li\u003e\n\u003cli\u003e3\/32 inch hex socket drive for use with a standard hex key or Allen wrench\u003c\/li\u003e\n\u003cli\u003e1\/8 inch length under head for shallow-depth fastening applications\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSocket cap head profile allows installation in recessed or tight-clearance locations\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 100 pieces supports bulk stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw suitable for tapped metal holes and threaded inserts conforming to the 4-40 UNC thread standard.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a correctly sized 3\/32 inch hex key to avoid rounding the drive socket. Ensure the mating tapped hole or threaded insert matches the 4-40 UNC thread specification before installation. De-energize any electrical assembly and follow applicable NEC guidelines before fastening components on or near energized equipment. Do not overtighten in shallow tapped holes, as the short 1\/8 inch length under head limits thread engagement depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40 UNC\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\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/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\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: R40664448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692828164402,"sku":"R40664448","price":1025.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f92f8d382686a09d981c93e9b574a402.jpg?v=1788303603","url":"https:\/\/voomisupply.com\/products\/value-collection-r40664448-hex-socket-cap-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
