Machined from 6061-T3 aluminum with an anodized finish, this fastener meets the QQ-A-225A Comp 2 material standard. The standoff measures 0.8125 inches in overall length with a 0.625-inch hex body and a 1\/4-inch hex width across flats. The male thread protrudes 3\/16 inch and the female thread depth is 1\/4 inch, both in a 4-40 thread size. Licensed electricians, electronics technicians, and PCB assembly professionals install these fasteners during panel builds and control board mounting applications.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in electronic control panels, HVAC control boards, industrial enclosures, and other applications where secure, stacked PCB mounting is required. The 4-40 thread size is a common standard in light-duty electronics and low-voltage control board assemblies. The hex body shape allows installation and removal with standard nut drivers or hex wrenches, making it practical for production and field service environments alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female configuration allows daisy-chain stacking of circuit boards\u003c\/li\u003e\n\u003cli\u003e4-40 thread size on both male post and female receptacle\u003c\/li\u003e\n\u003cli\u003eHex body shape accepts standard 1\/4-inch nut driver for tool-driven installation\u003c\/li\u003e\n\u003cli\u003eAnodized aluminum construction provides corrosion resistance at low weight\u003c\/li\u003e\n\u003cli\u003eMeets QQ-A-225A Comp 2 material standard for aluminum fasteners\u003c\/li\u003e\n\u003cli\u003eLength tolerance held to plus or minus 0.005 inches for consistent board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-build component for circuit board assemblies requiring 4-40 threaded hex standoffs with a 13\/16-inch overall length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDe-energize all circuits before installing or removing standoffs in live control panels or PCB assemblies. Use a 1\/4-inch nut driver or appropriately sized hex tool to drive the male end into a tapped hole or mating female standoff. Avoid overtightening, which can strip the 4-40 threads in aluminum. Installation should follow applicable assembly drawings and any governing electrical codes for the panel type being serviced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.8125 inches (13\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMale Thread Length\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFemale Thread Depth\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum, T3 Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to +0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1439M06F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742946132274,"sku":"1439M06F16-440","price":18.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4130cafd7b8216371dc164ad1b03053.jpg?v=1788840625","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1439m06f16-440-hex-standoff-4-40-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
