Manufactured from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable mechanical separation and thread engagement in a compact metric form factor. The overall length is 15.97 mm (approximately 0.629 inches), the body length is 12.00 mm (approximately 0.472 inches), and the hexagonal body measures 4.50 mm (approximately 0.177 inches) across flats. Electronics assemblers, PCB technicians, and field service technicians working on control boards in HVAC, electrical, and similar trade equipment install this fastener during board mounting and chassis assembly operations.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric M2.5 x 0.45 thread applications in residential and commercial electronic control assemblies. Typical use cases include securing circuit boards at a fixed standoff height within enclosures, control panels, and equipment chassis where both a male threaded stud and a female threaded receiver are needed at opposite ends of the same fastener. The part is sold individually per package, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex configuration allows stacking or single-level board mounting in one fastener\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 metric thread on both ends for compatibility with standard metric hardware\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish resists corrosion and provides electrical conductivity\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 (4.50 mm across flats) allows installation and removal with standard hex tools\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.150 to 0.150 mm for consistent board spacing in precision assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a metric M2.5 x 0.45 male-female hex standoff for use in circuit board assemblies requiring brass construction and zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assembly technicians or field service personnel. Power down and de-energize all equipment completely before removing or installing circuit board standoffs. Use an appropriately sized hex driver or nut driver matched to the 4.50 mm across-flats dimension to avoid rounding the hex body. Do not over-torque; brass fasteners at this size are susceptible to thread stripping if excess force 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: 15.97 mm (0.629 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 12.00 mm (0.472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.97 mm (0.156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.80 mm (0.189 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (0.177 inches)\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: 0.012 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: MMF1317M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739737981234,"sku":"MMF1317M0321M25","price":21.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/058618b61ed1e7530ddb8e1d1ac45e5b.jpg?v=1788818380","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1317m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
