Machined from aluminum alloy to material grade T3 and finished to a plain bright uncoated surface, this standoff accepts a 4-40 threaded fastener on the female end with a full 0.5 inch thread depth. The hex body measures 3\/16 inch across flats, and the overall length is 0.5 inch. This hardware meets QQ-A-225A Comp 2 fastener standards, making it appropriate for electronics assembly work where dimensional consistency and material certification are required.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in PCB assembly, control board mounting, and electronics enclosure builds across residential and commercial HVAC equipment, industrial control panels, and general electronics manufacturing. Typical applications include separating stacked circuit boards, securing boards to chassis surfaces, and providing a threaded female receiver for machine screws in panel assemblies. The compact 0.5 inch OAL suits low-profile board-to-board or board-to-chassis installations where clearance is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale threaded hex standoff with 4-40 thread size and 0.5 inch full thread depth\u003c\/li\u003e\n  \u003cli\u003eAluminum construction, material grade T3, for lightweight corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003ePlain bright uncoated finish — ready for use without additional surface treatment\u003c\/li\u003e\n  \u003cli\u003eHex body profile at 3\/16 inch width across flats allows standard wrench or nut driver installation\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-A-225A Comp 2 fastener standard for documented material compliance\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to plus or minus 0.005 inch for consistent stack height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 female hex circuit board standoff suitable for PCB mounting and electronics enclosure assembly applications requiring a 0.5 inch overall length aluminum spacer with plain finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics assemblers or control board technicians using a nut driver or small wrench sized to the 3\/16 inch hex flats. Always de-energize the assembly and discharge any capacitors before working on circuit boards or control panels. Avoid over-torquing the mating 4-40 screw into the female thread, as aluminum threads can strip under excessive force. Follow applicable workplace and equipment manufacturer guidelines for ESD precautions when handling circuit boards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.1875 inches (3\/16 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain (Bright\/Uncoated)\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\u003eFastener Standard\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (package)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: P309M06F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51749503107378,"sku":"P309M06F16440","price":24.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69be0ea513ec4cbce20afd5016302ef1_b57900cf-22c0-458d-8c8e-e0823dd4aed2.jpg?v=1788906919","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p309m06f16440-hex-standoff-4-40-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
