It carries a 4-40 UNC thread and an under-head length of 21\/32 inches, making it suited for close-tolerance fastening applications where conventional loose fasteners are impractical. Constructed from 18-8 stainless steel with an uncoated finish, it resists corrosion in moderate environments. The head measures 5\/16 inches in diameter and 3\/16 inches in height. Mechanical and electrical technicians working on enclosures, panels, and electronic assemblies install this type of hardware during assembly and service operations.\u003c\/p\u003e\n\u003cp\u003eThis captive screw is used in panel fabrication, electronic enclosure assembly, and control box construction across industrial, commercial, and light trade applications. Its captive design prevents screw loss during repeated access cycles, which is especially useful in electrical panels, junction boxes, and instrument housings where small hardware must remain with the assembly between service visits. A standard flat-blade screwdriver is all that is required for installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCaptive design keeps screw retained in panel when disengaged, preventing hardware loss during service\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard for compatibility with common tapped panels and inserts\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in moderate-duty environments\u003c\/li\u003e\n  \u003cli\u003eSlotted drive accepts standard flat-blade screwdrivers  -  no specialty tooling required\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; no surface treatment to interfere with electrical grounding contact where applicable\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 material standard for stainless steel fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style captive panel fastener for assemblies tapped to 4-40 UNC thread specification.

Verify the mating panel or insert is tapped to 4-40 UNC specification before installation. Do not overtighten into thin sheet material, as stainless fasteners in light-gauge panels can strip threads if torque is not controlled. Follow applicable assembly documentation for the host equipment.\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\u003eUnder-Head Length\u003c\/strong\u003e: 21\/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\u003eWeight\u003c\/strong\u003e: 0.01816 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: 4101M07F16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743874416946,"sku":"4101M07F16","price":95.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60add77f02251caa6eeeeda53a866d1_1a9da75c-991b-4670-9bd7-f8f5b9952511.jpg?v=1788850653","url":"https:\/\/voomisupply.com\/products\/electro-hardware-4101m07f16-captive-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
