The standoff features an M2.5 x 0.45 threaded male end and a female threaded bore, allowing boards to be stacked or secured with a mating screw. Constructed from brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, it delivers reliable corrosion resistance and dimensional stability. Overall length is 24.97 mm (approximately 0.983 inches), with a hex body width across flats of 4.50 mm (approximately 0.177 inches). Electronic assemblers, field service technicians, and PCB rework specialists are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in residential and commercial electronic control assemblies, instrumentation enclosures, industrial control panels, and HVAC or other trade-equipment circuit board assemblies. The male-female configuration allows daisy-chaining multiple standoffs for adjustable board spacing or single-layer mounting where a screw passes through to the female end. The hex body profile accepts a standard hex driver or wrench for torque-controlled installation without slipping. Its metric M2.5 x 0.45 thread pitch is common in compact PCB mounting applications where space is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex configuration supports stacked PCB assemblies and single-board panel mounting\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 metric thread on both male and female ends for consistent engagement\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22\u003c\/li\u003e\n  \u003cli\u003eOverall length of 24.97 mm with a length tolerance of -0.150 to 0.150 mm for precision fitment\u003c\/li\u003e\n  \u003cli\u003e4.50 mm hex body width across flats accepts standard metric hex tooling\u003c\/li\u003e\n  \u003cli\u003eThread depth of 4.80 mm and thread length of 3.97 mm for secure fastener engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard M2.5 x 0.45 metric male-female hex standoff suitable for circuit board mounting applications requiring brass construction with a zinc-plated finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eElectronic assemblers and PCB technicians typically install these standoffs using a hex driver or wrench sized to the 4.50 mm flats. Power down and de-energize all boards and enclosures before installing or removing standoffs. Avoid over-torquing brass hardware, as the material is softer than steel and threads can strip under excessive force. Follow applicable IPC assembly standards and enclosure manufacturer guidelines for proper standoff spacing and torque procedures.\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: 24.97 mm (approximately 0.983 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 21.00 mm (approximately 0.827 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.97 mm (approximately 0.156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.80 mm (approximately 0.189 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\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (approximately 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\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: 0.008 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: MMF1333M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743559680306,"sku":"MMF1333M0321M25","price":22.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/058618b61ed1e7530ddb8e1d1ac45e5b_bee50afa-993b-4b27-942d-5bd44d2016e7.jpg?v=1788848125","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1333m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
