Built from 18-8 stainless steel in an uncoated finish, this fastener offers solid corrosion resistance for light industrial and electronic enclosure applications. The 4-40 UNC thread with a 25\/32-inch length under head suits standard low-clearance panel and chassis installations. A 5\/16-inch head diameter and 3\/16-inch head height keep the profile low while providing a positive slotted driver engagement. Certified to QQ-S-763, it meets material and dimensional standards commonly required in OEM and service assembly work.\u003c\/p\u003e\n\u003cp\u003eThis captive screw is suited for use in control panels, electronic enclosures, HVAC equipment chassis, and similar assemblies where technicians require repeated access without losing hardware. The 4-40 UNC thread size is a common fit in light-gauge sheet metal and PCB-mounted standoff applications. Trade professionals installing or servicing electrical enclosures, control boards, or equipment panels will find this fastener appropriate for applications demanding retained hardware and corrosion-resistant material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction meets QQ-S-763 material standard\u003c\/li\u003e\n  \u003cli\u003eCaptive design keeps screw retained in panel after removal for tool-free access cycles\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard suits common light-gauge panel and chassis applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish  -  no added plating that could affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eLow-profile head at 3\/16 inch height minimizes clearance requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style captive screw replacement for assemblies using 4-40 UNC threaded hardware in light industrial, electronic, and HVAC control panel applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal require a flat-blade screwdriver sized for a slotted 4-40 fastener. De-energize any electrical enclosure or control panel fully before servicing retained hardware per applicable NEC guidelines. Do not overtighten into light-gauge sheet metal or PCB-mounted standoffs, as thread stripping can occur without a torque-limiting driver. Verify mating thread condition before reinstalling captive screws to avoid cross-threading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\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: 25\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161510\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02064 pounds\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: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4103M07F16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739844575538,"sku":"4103M07F16","price":77.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60add77f02251caa6eeeeda53a866d1.jpg?v=1788819548","url":"https:\/\/voomisupply.com\/products\/electro-hardware-4103m07f16-captive-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
