It carries a 4-40 UNC thread with a 15\/32-inch length under the head, measured as 0.468 inches decimal. The fastener is machined from 18-8 stainless steel and left uncoated, giving it solid corrosion resistance without added surface treatments. The rounded head measures 0.25 inches in diameter and 0.125 inches in height. This screw suits electronic enclosures, control panels, and light industrial assemblies where tool-accessible, captive fastening is required.\u003c\/p\u003e\n\u003cp\u003eCaptive screws like the 4501-M07-F16 are commonly installed in control panel doors, access covers, and chassis assemblies across HVAC controls, electrical enclosures, and instrumentation housings. The slotted drive accepts a standard flat-blade screwdriver, making it accessible in tight service environments. The 4-40 UNC thread is a fine-pitch standard widely used in light-gauge metal panels. This screw is sold individually per package with a minimum order quantity of 5 units, which should be accounted for when placing orders for service stock or new panel builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCaptive design keeps the screw retained in the panel when disengaged, preventing loss during service\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard suits light-gauge metal and thin panel applications\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance without plating or coating\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers\u003c\/li\u003e\n  \u003cli\u003eRounded head with 0.25-inch diameter and 0.125-inch height for low-profile seating\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 stainless steel material standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style captive fastener for light-gauge metal panels and enclosures using 4-40 UNC threaded inserts or clinch hardware in control panel and chassis applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard flat-blade screwdriver sized to the slotted head. Confirm the mating panel insert or threaded hole is tapped to 4-40 UNC before installing. Do not overtorque small-diameter stainless fasteners, as galling can occur; apply thread lubricant if repeated removal is expected. Shut down and de-energize any enclosure or control panel before accessing captive fasteners on live equipment.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.468 inches (15\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.125 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\u003eWeight\u003c\/strong\u003e: 0.00856 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 4501-M07-F16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740475556146,"sku":"4501-M07-F16","price":37.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cabebe986474c454466474688f5478b1_14e0a88e-9f87-4c75-97a4-9362aece0905.jpg?v=1788825250","url":"https:\/\/voomisupply.com\/products\/electro-hardware-4501-m07-f16-captive-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
