The body is fully threaded with an M2.5 x 0.45 metric thread, a 16 mm overall length, and a full 16 mm thread depth. Manufactured from brass with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22, this standoff provides corrosion resistance and reliable electrical isolation in panel-mount and rack-mount applications. Electricians, control panel builders, and electronics technicians install these when assembling low-voltage control boards and instrumentation enclosures.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric PCB assemblies requiring precise board-to-board or board-to-chassis spacing. The hex body profile  -  4.5 mm width across flats  -  allows installation and torque with standard hex drivers or wrenches without marring the body. Typical applications include HVAC control board assemblies, industrial enclosures, and electrical panel subassemblies where secure, repeatable standoff height is required. The zinc-plated brass construction makes it appropriate for indoor and light-duty protected environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM2.5 x 0.45 metric female thread, fully threaded to full 16 mm depth\u003c\/li\u003e\n  \u003cli\u003eHex body with 4.5 mm width across flats for tool-driven installation\u003c\/li\u003e\n  \u003cli\u003eBrass base material with clear zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.13 to 0.13 mm for consistent stack height\u003c\/li\u003e\n  \u003cli\u003eMetric system of measurement  -  direct fit for M2.5 metric fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style metric standoff for circuit board and panel assemblies using M2.5 x 0.45 metric thread fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by control panel assemblers or electronics technicians. Power down and de-energize all circuits before servicing any board or enclosure assembly. Use a hex driver or open-end wrench sized to 4.5 mm across flats to seat the standoff without over-torquing the brass body. Follow applicable assembly drawings and any governing enclosure or panel standards for your application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 16 mm (approximately 0.630 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 16 mm\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 mm (approximately 0.177 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 mm\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: 0.012 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: MP431M03F21M2.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739653013810,"sku":"MP431M03F21M2.5","price":30.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fc684cde045c4d1faff9ecaafacd443_a835b9a8-624f-4a93-868b-e90589a5c345.jpg?v=1788817372","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp431m03f21m2-5-female-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
