Machined from brass with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 specifications, this standoff delivers corrosion resistance and reliable thread engagement in tight electronic assemblies. The body is fully threaded to a depth of 7 mm on an M3 x 0.5 thread, providing maximum thread contact for secure fastening. Electronics assemblers, panel builders, and field service technicians working on control boards, drives, and enclosure sub-assemblies commonly install this hardware.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric-threaded circuit board mounting applications in commercial and industrial electronic assemblies. The hex body profile allows installation and removal with standard nut drivers or hex wrenches, making it practical for production environments and service work alike. With an overall length of 7 mm and a width across flats of 4.5 mm, it fits compact board layouts where spacing and clearance are critical. It is appropriate for use wherever an M3 x 0.5 female threaded spacer is required in a PCB stack-up.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 female thread, fully threaded to 7 mm depth for maximum engagement\u003c\/li\u003e\n  \u003cli\u003eBrass construction 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\u003eHex body profile  -  4.5 mm width across flats  -  accepts standard nut drivers\u003c\/li\u003e\n  \u003cli\u003eCompact 7 mm overall length suits tight PCB stack-up clearances\u003c\/li\u003e\n  \u003cli\u003eLength tolerance held to -0.13 to 0.13 mm for consistent board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for any circuit board assembly requiring an M3 x 0.5 female hex threaded spacer with a 7 mm overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assemblers or technicians working on control boards and panel enclosures. Always de-energize and discharge the board assembly before installing or removing standoffs. Use a correctly sized nut driver matched to the 4.5 mm hex to avoid rounding the flats. Do not overtighten  -  brass threads can strip if torque is applied beyond hand-tight plus a controlled snug turn.\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: M3 x 0.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 mm (approximately 0.276 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 7 mm\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\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: Clear Zinc Chromate\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\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: 0.00288 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: MP413M03F21M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743948210482,"sku":"MP413M03F21M3","price":21.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fc684cde045c4d1faff9ecaafacd443_3371ed1f-720f-4674-b65a-c2d3c6f5e981.jpg?v=1788851768","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp413m03f21m3-female-hex-standoff-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
