Machined from aluminum alloy to material grade T-3 and finished with an anodized bright coating, this standoff meets QQ-A-225A Comp 2 specification. It features a 4-40 female thread, a 1 inch overall length, and a 1\/4 inch hex body width across flats. The hexagonal body allows wrench engagement for accurate torque control during installation. This hardware is used by electronics assemblers, electrical panel builders, HVAC control board technicians, and field service technicians working with control systems.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for residential and commercial electronic control assemblies where a threaded female-to-female or male-to-female board mounting solution is needed. The 4-40 thread size is standard in low-voltage control boards, relay panels, and similar equipment. The 1 inch overall body length provides a fixed standoff distance of 1 inch between mating surfaces. Anodized aluminum construction offers corrosion resistance in typical indoor panel and equipment cabinet environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale 4-40 threaded hex standoff for secure board-to-board or board-to-chassis mounting\u003c\/li\u003e\n  \u003cli\u003e1 inch overall length with a tight length tolerance of -0.005 to +0.005 inches for consistent stack height\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch width across flats enables standard hex wrench or nut driver installation\u003c\/li\u003e\n  \u003cli\u003eAluminum construction with anodized bright finish for corrosion resistance and surface hardness\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-A-225A Comp 2 federal specification for aluminum bar stock material grade T-3\u003c\/li\u003e\n  \u003cli\u003eHex body shape prevents rotation during assembly and allows positive torque engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 female hex standoff for use in circuit board mounting applications where a 1 inch spacing height and 1\/4 inch hex body are required. Consult your assembly drawing or BOM to confirm thread size, overall length, and hex width before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize all equipment and discharge any stored energy before installing or removing circuit board hardware. Use a properly sized hex wrench or nut driver matched to the 1\/4 inch across-flats dimension to avoid rounding the hex body. Do not overtighten  -  aluminum threads are susceptible to galling and stripping when excessive torque is applied. Installation in commercial electrical enclosures should conform to applicable NEC requirements for panel construction and component mounting.\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: 1 inch\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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Anodized Bright\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\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: P561M06F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739970863410,"sku":"P561M06F16-440","price":15.66,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b443ff4c9def03e940d29346245b020c.jpg?v=1788820885","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p561m06f16-440-hex-standoff-4-40-1in","provider":"Voomi Supply","version":"1.0","type":"link"}
