Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable electrical isolation and structural support. The M4 x 0.7 fully threaded female bore runs the entire 13 mm overall length, allowing a mating male fastener to engage from either end. The hexagonal body measures 6 mm across flats, making it wrench-accessible for installation in tight PCB layouts. Electronics assemblers, field service technicians, and panel builders use this hardware in control boards, enclosures, and rack-mounted equipment.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric PCB assemblies in both commercial and industrial applications where consistent board standoff height and secure mechanical attachment are required. Typical use cases include HVAC control board assemblies, electrical panel sub-assemblies, and industrial equipment where a fully threaded female standoff must accept an M4 x 0.7 screw from the board side. The fully threaded bore and brass construction make it appropriate where mild corrosion resistance and electrical conductivity through the standoff are needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM4 x 0.7 fully threaded female bore with 13 mm thread depth for full-length engagement\u003c\/li\u003e\n  \u003cli\u003e13 mm overall length provides consistent, measurable board standoff height\u003c\/li\u003e\n  \u003cli\u003eHexagonal body at 6 mm across flats allows installation and removal with standard hex wrenches or nut drivers\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\u003eLength tolerance held to plus or minus 0.13 mm for precise stack-up control in multi-board assemblies\u003c\/li\u003e\n  \u003cli\u003eMetric thread system for compatibility with M4 hardware used in modern electronic and control equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-build component for metric PCB assemblies requiring M4 x 0.7 female hex standoffs with a 13 mm overall length and 6 mm hex body.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and de-energize any control board or panel before installing or removing standoffs to prevent short circuits or component damage. Use an appropriately sized hex wrench or nut driver on the 6 mm flats — avoid pliers or gripping tools that can deform the hex body or damage the plating. Thread engagement should be confirmed on both the board-side and chassis-side fasteners before final torque. Follow applicable IPC or equipment manufacturer guidelines for PCB mounting hardware installation.\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: M4 x 0.7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 13 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 13 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: 6 mm\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: 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: 0.81 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: MP1025M03F21M4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728640114994,"sku":"MP1025M03F21M4","price":15.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a51e351945e7707ff4ed473b9a1abb6d_d660941d-59d6-4241-bcef-3258a9aef361.jpg?v=1788694300","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp1025m03f21m4-female-hex-standoff-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
