The 3\/32 inch internal hex drive accepts a standard Allen key or hex bit driver, and the screw measures 1\/4 inch length under head. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet, mildly acidic, or outdoor environments. It is suited for light mechanical assemblies, instrument panels, electrical enclosures, and equipment housings where a flush or low-profile head is required. Maintenance technicians, electricians, and mechanical contractors commonly specify this style in confined-space fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is used in residential and commercial mechanical, electrical, and instrumentation assemblies. The 5-40 UNC thread is a fine-pitch unified coarse designation commonly found in small-diameter fastening applications within control panels, junction boxes, and light-duty mechanical subassemblies. Its stainless steel construction makes it appropriate for environments where mild corrosion resistance is needed without the cost of exotic alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread for small-diameter, light-load fastening applications\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch length under head for shallow-clearance fastening\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in moist or mildly corrosive environments\u003c\/li\u003e\n  \u003cli\u003eLow-profile socket cap head allows flush or recessed installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5-40 UNC hex socket cap screw suitable for use in small mechanical assemblies, control enclosures, instrumentation hardware, and equipment requiring 18-8 stainless steel fasteners with a 3\/32 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/32 inch hex key or Allen driver; use of an incorrect driver size risks rounding the socket. Power down or de-energize any electrical enclosure before fastening work begins. Follow applicable codes such as NEC for electrical enclosures or manufacturer torque guidelines for the mating component material. Avoid over-torquing stainless steel fasteners, as galling can occur without proper anti-seize compound on the threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inches\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\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: R40660421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709839343922,"sku":"R40660421","price":1463.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5dd36736b240dbe81d99e0d7b151d4fb.jpg?v=1788461206","url":"https:\/\/voomisupply.com\/products\/value-collection-r40660421-hex-socket-cap-screw-5-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
