Machined from aluminum alloy to the QQ-A-225A Comp 2 standard, this standoff features an M2.5 x 0.45 thread on both the male and female ends. The hex body measures 4.5 mm across flats for wrench engagement. Overall length is 13.97 mm, with a 10.00 mm body length and a 3.97 mm thread length on the male end. Electronics assembly technicians and field service techs use this fastener in board-level hardware assembly and rework.\u003c\/p\u003e\u003cp\u003eThis standoff is used in electronic control assemblies where precise board separation is required. Common applications include HVAC control boards, industrial control panels, and OEM electronics assemblies that specify metric M2.5 hardware. The hex profile allows installation with standard open-end or socket wrenches, making it suitable for both bench assembly and field service environments. The bright uncoated aluminum finish is appropriate for indoor enclosure use where corrosion exposure is minimal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female configuration allows daisy-chaining of stacked board assemblies\u003c\/li\u003e\n\u003cli\u003eM2.5 x 0.45 metric thread on both ends for precise fitment\u003c\/li\u003e\n\u003cli\u003eHex body at 4.5 mm across flats accepts standard wrenches for torque control\u003c\/li\u003e\n\u003cli\u003eOverall length of 13.97 mm with a 10.00 mm body length for consistent board spacing\u003c\/li\u003e\n\u003cli\u003eAluminum construction per QQ-A-225A Comp 2 for lightweight, non-magnetic installation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish  -  no coating contamination risk on sensitive PCB assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any assembly requiring M2.5 x 0.45 metric hex standoff hardware for circuit board mounting and stacking applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires appropriate M2.5 metric tooling; use a hex socket or open-end wrench on the 4.5 mm flats to seat the standoff without damaging the board. Power down and discharge any capacitors in the control assembly before removing or installing board-level hardware. Do not over-torque aluminum standoffs, as the material is softer than steel and threads can strip under excessive force. Follow the equipment manufacturer's assembly specifications for board spacing and fastener engagement depth.\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 and Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 13.97 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male End)\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female End)\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm\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, Grade T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\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\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: 0.0016 pounds\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: MMF1311M0616M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743299371314,"sku":"MMF1311M0616M25","price":51.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec8ea8736a63f7a7ac6771c08f99a10b_bdbf0e73-a09a-4c60-ba2f-cf402b4e5c5f.jpg?v=1788845285","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1311m0616m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
