Machined from aluminum alloy to QQ-A-225A Comp 2 specification, this standoff features an M2.5 x 0.45 thread on both ends and a hexagonal body for wrench engagement. The overall length is 19.97 mm (0.79 inches), with a 16.00 mm (0.63 inches) hex body and a 4.50 mm (0.18 inches) width across flats. The bright uncoated finish suits applications where anodizing or plating is not required. Electronics assemblers and PCB technicians install these standoffs in control boards, enclosures, and panel assemblies.\u003c\/p\u003e\u003cp\u003eThis standoff is used in metric fastener applications where M2.5 x 0.45 threading is required for board-level spacing and mounting. Typical install scenarios include electronic control enclosures, instrumentation panels, and stacked circuit board assemblies found in HVAC control systems, electrical panels, and similar trade equipment. The male thread engages a tapped hole or nut on the mating surface, while the female thread accepts a machine screw to secure the next board or component in the stack.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2.5 x 0.45 male-female thread configuration for stacked PCB or board-to-chassis mounting\u003c\/li\u003e\n\u003cli\u003eHexagonal body with 4.50 mm width across flats allows standard hex driver or wrench installation\u003c\/li\u003e\n\u003cli\u003eOverall length of 19.97 mm (0.79 inches) provides consistent board spacing in metric assemblies\u003c\/li\u003e\n\u003cli\u003eAluminum construction to QQ-A-225A Comp 2 standard, Material Grade T3\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish  -  no additional coating to interfere with tight-tolerance fits\u003c\/li\u003e\n\u003cli\u003eThread depth of 4.80 mm with length tolerance of -0.150 to 0.150 mm for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for metric PCB and panel assemblies requiring M2.5 x 0.45 male-female hex standoffs with a 4.50 mm hex body width.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eElectronics technicians install this standoff using a hex driver or appropriately sized wrench matched to the 4.50 mm flats. Ensure the mating hole or tapped insert is clean and properly sized for M2.5 x 0.45 threads before installation. De-energize all boards and assemblies before removing or installing standoffs in live control panels. Avoid over-torquing aluminum standoffs, as the alloy is softer than steel and threads can be damaged by excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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 Type\u003c\/strong\u003e: Male \/ Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19.97 mm (0.79 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 16.00 mm (0.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.97 mm (0.16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.80 mm (0.19 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 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: 4.50 mm (0.18 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum, Grade T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00216 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MMF1323M0616M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743476351282,"sku":"MMF1323M0616M25","price":41.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec8ea8736a63f7a7ac6771c08f99a10b_2cfb5e41-241c-49fa-bdab-c85c82542f5b.jpg?v=1788847460","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1323m0616m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
