This fastener features an M2.5 x 0.45 metric thread on both the male and female ends, with an overall length of 13.97 mm and a body length of 10.00 mm. The hex body measures 4.50 mm across flats for secure tool engagement. Constructed from brass and finished with zinc plating to ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff delivers corrosion resistance suitable for industrial electronic enclosures, control boards, and commercial equipment assemblies. Electronics technicians and panel builders are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric circuit board mounting applications in HVAC control panels, electrical enclosures, industrial equipment, and commercial electronics where PCB layering or board-to-chassis spacing is required. The male-female configuration allows for modular stacking, making it appropriate for multi-board assemblies where consistent spacing and secure mechanical registration are critical. The metric M2.5 x 0.45 thread pitch is common in compact control board and sensor module mounting scenarios found across HVAC, electrical, and light industrial equipment platforms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2.5 x 0.45 metric thread on both male and female ends for modular stacking capability\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc plating meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n  \u003cli\u003eHex body at 4.50 mm across flats allows wrench or socket installation without slippage\u003c\/li\u003e\n  \u003cli\u003eOverall length of 13.97 mm with a thread depth of 4.80 mm for reliable thread engagement\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to -0.150 to 0.150 mm for consistent PCB stack height\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 10 units suits professional service and assembly applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric standoff for circuit board mounting applications requiring M2.5 x 0.45 male-female hex fasteners in electronic assemblies and control panel builds.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or panel builders. Always de-energize and discharge any control board or enclosure before servicing PCB hardware. Use an appropriately sized hex wrench or nut driver on the 4.50 mm flats to avoid rounding the body. Do not overtighten, as brass standoffs can be damaged by excessive torque, especially in thin PCB mounting holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 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\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\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\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\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: 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: 0.00488 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: MMF1311M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739491369266,"sku":"MMF1311M0321M25","price":21.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cdd95ceeed2f014adc589aad368af63.jpg?v=1788815185","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1311m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
