Manufactured from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff offers reliable corrosion resistance and electrical conductivity in tight board-level assemblies. The metric M2.5 x 0.45 thread size and hexagonal body allow secure hand or tool tightening without marring the fastener faces. Overall length is 28.97 mm (approximately 1.14 inches), with a 25.00 mm (approximately 0.98 inches) body length and a hex width across flats of 4.50 mm (approximately 0.18 inches).\u003c\/p\u003e\u003cp\u003eThis standoff is used in electronics assembly, control panel fabrication, and equipment enclosure builds where metric fastening is required. Common applications include industrial control boards, HVAC and building automation PCB assemblies, power supply mounting, and any application where a board must be elevated and secured to a chassis or secondary board with a male thread on one end and a female thread on the other. The metric sizing suits European-standard and metric-native equipment platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female hex configuration allows stacking of multiple boards or secure chassis mounting in a single fastener\u003c\/li\u003e\n\u003cli\u003eM2.5 x 0.45 metric thread on both ends for consistent thread engagement with standard metric hardware\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHexagonal body (4.50 mm width across flats) accepts standard hex drivers for controlled installation torque\u003c\/li\u003e\n\u003cli\u003eOverall length of 28.97 mm with a length tolerance of -0.150 to +0.150 mm for consistent stack height\u003c\/li\u003e\n\u003cli\u003eThread depth of 4.80 mm and thread length of 3.97 mm provide adequate engagement for secure board retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M2.5 x 0.45 male-female hex standoff for use with any PCB, chassis, or enclosure that accepts M2.5 metric thread hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics assemblers or control panel technicians. Always power down and de-energize the equipment before installing or removing standoffs from a live circuit board assembly. Use a properly sized hex driver or nut driver matching the 4.50 mm width across flats to avoid rounding the hex body. Follow applicable IPC assembly standards and equipment manufacturer torque guidelines when securing boards to prevent PCB stress or cracking.\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: 28.97 mm (approximately 1.14 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 25.00 mm (approximately 0.98 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.97 mm\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: 0.0091 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MMF1341M0321M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743937265970,"sku":"MMF1341M0321M25","price":23.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/058618b61ed1e7530ddb8e1d1ac45e5b_b591cecd-eaff-4374-8147-9ead3d6b12a0.jpg?v=1788851577","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1341m0321m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
