Machined from brass with a clear zinc chromate (zinc-plated) finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides a threaded female receiver on one end to accept a mating screw. The metric M2.5 x 0.45 thread runs to a depth of 4.8 mm, and the overall length is 25 mm. The hexagonal body measures 4.5 mm across flats, allowing a standard nut driver or hex wrench to seat and torque the standoff securely without slipping.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in residential and commercial electronic assemblies wherever PCB spacing, isolation, or secure mounting is required. Typical applications include HVAC control boards, electrical control panels, motor drives, and general-purpose electronics enclosures. The metric M2.5 thread size is common in compact PCB assemblies and instrument housings. Electricians, controls technicians, and electronics assemblers install these standoffs during panel builds, board replacements, or enclosure modifications where consistent board-to-surface clearance is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale hex body accepts mating M2.5 x 0.45 screw for secure PCB mounting\u003c\/li\u003e\n  \u003cli\u003e25 mm overall length provides consistent board-to-surface spacing\u003c\/li\u003e\n  \u003cli\u003e4.8 mm thread depth gives adequate thread engagement for M2.5 fasteners\u003c\/li\u003e\n  \u003cli\u003eBrass construction with clear zinc chromate finish resists corrosion\u003c\/li\u003e\n  \u003cli\u003eHexagonal 4.5 mm across-flats body allows positive wrench engagement\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for printed circuit board assemblies requiring a metric M2.5 x 0.45 female hex standoff with a 25 mm overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electricians or electronics assembly technicians. Always de-energize and lock out the control panel or enclosure before installing or removing circuit board standoffs. Use an appropriately sized nut driver or hex wrench matched to the 4.5 mm across-flats hex body to seat the standoff without damaging the board or enclosure material. Follow applicable NEC guidelines and equipment manufacturer instructions when working inside energized control enclosures.\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: M2.5 x 0.45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Clear Zinc Chromate (Zinc-Plated)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM B633 Type 1, QQ-B-626 Comp 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.008 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MP449M03F21M2.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739379302706,"sku":"MP449M03F21M2.5","price":76.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fc684cde045c4d1faff9ecaafacd443_b622f3d8-2a20-4fc7-9845-3cdcbf81571c.jpg?v=1788813808","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp449m03f21m2-5-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
