This screw uses a 3\/32 inch internal hex drive and a 5-40 UNC thread form, with 1 inch of length measured under the head. It is manufactured from 18-8 stainless steel, which provides corrosion resistance suitable for both indoor and outdoor environments. Electricians, HVAC technicians, and mechanical tradespeople use socket cap screws like this one when a low-profile, high-strength fastener is needed in confined assemblies or equipment enclosures.\u003c\/p\u003e\u003cp\u003eThis fastener fits applications across light mechanical assemblies, electrical panel components, HVAC equipment housings, and general trade fabrication where a 5-40 UNC thread is specified. The fine thread pitch of the 5-40 UNC designation provides good resistance to loosening under vibration, making it appropriate for equipment subject to operational movement. It is sold individually but requires a minimum order quantity of 100 pieces per transaction, making it suited for contractors and shop stock replenishment rather than single-fastener replacement needs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-40 UNC thread size with 1 inch length under head for precise fitment in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e3\/32 inch internal hex drive accepts standard hex keys and ball-end drivers\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction resists corrosion in humid or outdoor service environments\u003c\/li\u003e\n\u003cli\u003eFine thread pitch improves resistance to vibration-induced loosening\u003c\/li\u003e\n\u003cli\u003eLow-profile socket cap head design suits recessed or flush-mount fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5-40 UNC hex socket cap screw for use in any application requiring that thread size and a 3\/32 inch hex drive, including light mechanical assemblies, control enclosures, and equipment panels.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/32 inch hex key or T-handle driver; a ball-end driver is useful when access angle is limited. Ensure the mating tapped hole is clean and the thread form matches 5-40 UNC before driving. De-energize any electrical equipment fully before working on enclosures or panels where these fasteners are used. Do not overtighten stainless steel fasteners in stainless tapped holes, as galling can occur; apply an appropriate anti-seize compound if the application permits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inch\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 inch\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: 0.004 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: R40660144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689886875954,"sku":"R40660144","price":2523.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55e1e1ba3560b711c24ccaae0f3adac6.jpg?v=1788265186","url":"https:\/\/voomisupply.com\/products\/value-collection-r40660144-hex-socket-cap-screw-5-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
