The fastener features an M4 x 0.7 thread on both the male and female ends, an overall length of 19.53 mm, and a 6 mm hex body for wrench engagement. Constructed from brass with a zinc plating finish, it meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. This standoff is installed by electronics assemblers, control panel technicians, and field service techs who need reliable, repeatable board-to-board or board-to-chassis spacing in metric fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in control panels, HVAC control board assemblies, electrical enclosures, and similar equipment where circuit boards require fixed separation from mounting surfaces or adjacent boards. The metric M4 x 0.7 thread pitch makes it appropriate for OEM equipment and aftermarket assemblies built to metric fastener standards. Its compact hex body allows installation in tight board layouts where clearance is limited. Sold individually per package with a minimum order quantity of 2 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM4 x 0.7 thread on both male and female ends for direct metric board-to-board or board-to-chassis stacking\u003c\/li\u003e\n  \u003cli\u003e6 mm width across flats allows standard hex wrench or nut driver installation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 19.53 mm with a 10 mm hex body length and 9.53 mm thread length\u003c\/li\u003e\n  \u003cli\u003eThread depth of 7.50 mm on the female end for secure thread engagement\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc plating resists corrosion in panel and enclosure environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in metric fastener assemblies requiring M4 x 0.7 male-female hex standoffs, including circuit board mounting applications in control panels and electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics assemblers or control panel technicians using a 6 mm hex wrench or appropriately sized nut driver. De-energize and disconnect power to any circuit board assembly before installing or removing standoffs. Avoid over-torquing, as brass hardware is subject to thread damage if excessive force is applied. Follow applicable IPC assembly standards and enclosure manufacturer guidelines for standoff placement and spacing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4 x 0.7\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: 19.53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 7.50 mm\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: -0.150 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.13 pounds\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: MMF1811M03F21M4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51752037318962,"sku":"MMF1811M03F21M4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7be0c19661ae9294c0fdba3369c41cd_8652daf2-2b3c-425e-a77b-eb52250d9771.jpg?v=1788925428","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1811m03f21m4-m4x0-7-hex-standoff","provider":"Voomi Supply","version":"1.0","type":"link"}
