The standoff features a metric M2.5 x 0.45 thread on both ends  -  a male thread on one side and a female threaded bore on the other  -  allowing boards to be stacked or secured at a consistent standoff height. The body is brass with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. Overall length is 26.97 mm (approximately 1.062 inches), with a hex body width across flats of 4.50 mm (approximately 0.177 inches). This hardware is used by electronics assemblers, panel builders, and electricians working on control board installations and enclosure builds.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for metric PCB mounting applications in residential and commercial control panels, HVAC control boards, low-voltage electronics enclosures, and similar assemblies requiring precise board-to-board or board-to-chassis spacing. The hex body profile allows easy tightening and removal with standard hex tooling. The minimum order quantity is 10 pieces per order, with individual package quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female thread configuration allows stackable PCB mounting at a defined standoff height\u003c\/li\u003e\n\u003cli\u003eM2.5 x 0.45 metric thread on both ends with a 3.97 mm thread length on the male side and 4.80 mm thread depth on the female side\u003c\/li\u003e\n\u003cli\u003eHex body profile (4.50 mm width across flats) accepts standard hex drivers for secure installation\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n\u003cli\u003eOverall length of 26.97 mm with a length tolerance of -0.150 to 0.150 mm for consistent fitment\u003c\/li\u003e\n\u003cli\u003eBody length of 23.00 mm provides the unthreaded hex standoff span between mating surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M2.5 x 0.45 metric threaded fastener applications including PCB stacking, panel mounting, and circuit board chassis assemblies requiring a hex standoff spacer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by panel builders, electronics assemblers, and electricians during control board or enclosure assembly. Always de-energize and lock out the panel or enclosure before installing or removing standoffs in live assemblies. Use an appropriately sized hex driver or open-end wrench sized to 4.50 mm across flats  -  do not use pliers, which can deform the hex faces. Verify thread engagement on both the male and female ends before applying torque to avoid cross-threading in PCB mounting holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 26.97 mm (approximately 1.062 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 23.00 mm (approximately 0.906 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 3.97 mm (approximately 0.156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 4.80 mm (approximately 0.189 inches)\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\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: 0.00848 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MMF1337M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742336876850,"sku":"MMF1337M0321M25","price":23.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/058618b61ed1e7530ddb8e1d1ac45e5b_a864aa8f-eddb-4a06-af04-29fb2d5ee943.jpg?v=1788836840","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1337m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
