Constructed from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable conductivity, corrosion resistance, and mechanical stability. The metric M2.5 x 0.45 thread size suits compact board mounting applications. Overall length measures 19.97 mm with a hex body width across flats of 4.50 mm, making it compatible with standard hex drivers and socket tools used in panel assembly and board-level service work.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in residential and light commercial control board assemblies, including HVAC equipment control panels, electrical enclosures, and industrial PCB mounting applications. The male-female configuration allows boards to be stacked or elevated off a mounting surface at a fixed standoff height, keeping boards secure while allowing airflow and maintaining electrical isolation from the chassis where required. Installers working on circuit board replacement or panel retrofits commonly use this style of standoff to restore factory board mounting geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex configuration for PCB stacking and board-to-chassis mounting\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 metric thread for precise, low-torque engagement on compact boards\u003c\/li\u003e\n  \u003cli\u003eBrass base material with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards\u003c\/li\u003e\n  \u003cli\u003eHexagonal body allows positive wrench engagement without slipping\u003c\/li\u003e\n  \u003cli\u003eOverall length of 19.97 mm with 3.97 mm male thread length and 4.80 mm female thread depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for PCB assemblies requiring M2.5 x 0.45 metric male-female hex standoffs with a 4.50 mm width across flats.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians, HVAC controls specialists, or electricians servicing control board assemblies. Always de-energize the equipment and discharge any capacitors before removing or installing circuit board hardware. Use a calibrated hex driver or nut driver sized for a 4.50 mm hex body to avoid deforming the standoff. Do not overtighten  -  brass hardware is subject to thread stripping if excessive torque is applied.\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 and Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Length\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Thread 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\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\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 mm\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: 0.00656 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: MMF1323M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739840512306,"sku":"MMF1323M0321M25","price":22.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5d947b12fa6c19db9b148fd4a3aa29c.jpg?v=1788819454","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1323m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
