Manufactured from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides corrosion resistance and reliable conductivity in tight board-mounting applications. The metric M2.5 x 0.45 thread profile runs on both the male and female ends, allowing boards to be stacked or mounted to a chassis with consistent spacing. With an overall length of approximately 0.39 inches and a hexagonal body that measures 0.18 inches across the flats, this hardware is suited for precision electronics assembly work performed by electronics technicians and PCB assembly professionals.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in residential and commercial electronic control assemblies, including HVAC control boards, industrial PCB enclosures, and general electronic chassis mounting applications. The hex body shape allows installation and removal with standard hex drivers or small wrenches, making it practical for field service and bench assembly alike. It is sold individually but must be ordered in multiples of 10 to meet minimum order requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female configuration allows stacked board mounting or chassis-to-board attachment\u003c\/li\u003e\n  \u003cli\u003eBrass construction 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 shape for easy installation with standard hand tools\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 metric thread on both ends for compatibility with metric fastener systems\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of plus or minus 0.006 inches for consistent board spacing\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 assemblies requiring M2.5 x 0.45 male-female hex hardware with a 4.5 mm hex body width.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or qualified assembly personnel. Power down and discharge any capacitors in the assembly before handling circuit boards or installing standoffs. Use an appropriately sized hex driver or small wrench on the hex body to avoid stripping the plating or deforming the body. Follow applicable IPC assembly standards and the board or enclosure manufacturer guidelines for torque and spacing requirements.\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: 9.97 mm (approximately 0.39 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 6.00 mm (approximately 0.24 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.97 mm (approximately 0.16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.80 mm (approximately 0.19 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (approximately 0.18 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\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: 0.00376 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: MMF1303M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743286952242,"sku":"MMF1303M0321M25","price":20.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/058618b61ed1e7530ddb8e1d1ac45e5b_72f8d27e-f3e9-4b93-b64d-738e5eb6d562.jpg?v=1788845097","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1303m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
