Machined from brass with a clear zinc chromate finish per ASTM B633 Type 1 and QQ-B-626 Comp 22, this standoff accepts an M2.5 x 0.45 thread on the female end. The overall length is 8 millimeters with a full 8 millimeters of thread depth, meaning the fastener engages the entire body length. The hex profile measures 4.5 millimeters across the flats, allowing a standard hex driver or wrench to seat and torque the standoff without slipping. Electronics assemblers and field service technicians working on control boards in HVAC, electrical, and industrial equipment applications will encounter this hardware type regularly.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for metric PCB mounting applications in low-voltage control assemblies, industrial enclosures, and electronic equipment where a rigid, conductive spacer is required. The brass construction provides corrosion resistance and good electrical conductivity, while the zinc chromate finish adds a secondary layer of protection against oxidation in light-duty indoor environments. It is appropriate for residential and commercial control boards, drive enclosures, and panel-mount electronics requiring M2.5 metric fastening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2.5 x 0.45 female thread with full 8 millimeter thread depth for maximum engagement\u003c\/li\u003e\n\u003cli\u003eBrass body with clear zinc chromate finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22\u003c\/li\u003e\n\u003cli\u003eHex body profile  -  4.5 millimeters across the flats  -  allows wrench or driver installation\u003c\/li\u003e\n\u003cli\u003eFully threaded body length of 8 millimeters provides consistent standoff height\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.13 to 0.13 millimeters for precise board spacing\u003c\/li\u003e\n\u003cli\u003eMetric measurement system; compatible with standard M2.5 machine screws\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use as a metric PCB standoff in applications requiring an M2.5 x 0.45 female threaded hex spacer.

Always power down and de-energize equipment completely before servicing any circuit board assembly. Avoid over-tightening, as brass fasteners are softer than steel and can be damaged by excessive torque. Follow the equipment manufacturer's assembly documentation for standoff placement and fastener sequence.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.5 x 0.45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 millimeters (approximately 0.315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 8 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.5 millimeters (approximately 0.177 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 millimeters\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: Clear Zinc Chromate\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: 0.00312 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: MP415M03F21M2.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51742018044210,"sku":"MP415M03F21M2.5","price":21.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8712f68f9f8fe6253d446ac9f4842f0.jpg?v=1788834954","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp415m03f21m2-5-female-hex-standoff","provider":"Voomi Supply","version":"1.0","type":"link"}
