It features a 4-40 UNC thread size, a 3\/32 inch internal hex drive, and a 7\/8 inch length under head. Constructed from 18-8 stainless steel, this screw offers corrosion resistance suitable for both indoor and outdoor service environments. It is installed using a standard hex key or Allen driver and is a common choice for close-tolerance work where a flush or recessed fastener head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light-duty mechanical assemblies, instrument panels, control enclosures, electrical junction boxes, and HVAC equipment covers where a small-diameter, fine-thread fastener is needed. The 4-40 UNC thread is a standard size found in electronic hardware, precision instruments, and OEM equipment panels. Installers in electrical, HVAC, and general mechanical trades reach for this size when securing thin-gauge components or attaching cover plates with limited clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread for fine-pitch, secure engagement in tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex socket drive accepts standard Allen keys and hex drivers\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch length under head suits moderate-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eSocket cap head profile allows installation in recessed or countersunk locations\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 for use in any tapped or threaded insert rated for 4-40 UNC fasteners, including OEM equipment panels, control boards, and instrument enclosures requiring this thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/32 inch hex key or Allen driver. Ensure the mating tapped hole or threaded insert is clean and undamaged before driving the screw. De-energize any electrical equipment before fastening or removing screws on live panels or enclosures. Do not overtighten in thin-gauge or soft-material tapped holes, as 4-40 threads can strip under excessive torque.\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: 7\/8 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: R40664481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699654623538,"sku":"R40664481","price":555.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/827d381764bffd2177381cd0597e0f9b.jpg?v=1788378758","url":"https:\/\/voomisupply.com\/products\/value-collection-r40664481-hex-socket-cap-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
