Both ends carry M4 x 0.7 threaded studs, and the hexagonal body allows installation and removal with standard hex tooling. The standoff has a 20 mm overall length with a 20 mm body length and thread lengths ranging from 8.5 mm to 9.5 mm. Constructed from Grade 18-8 303 stainless steel with a passivated finish, it meets QQ-S-763 specification. Electronics assembly technicians and PCB integrators working in industrial, HVAC control, or electrical panel applications install this type of hardware during board-level assembly and field service.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric M4 applications wherever a rigid, corrosion-resistant board spacer is required. Common installation environments include HVAC control board assemblies, electrical enclosures, and industrial automation panels where stainless steel hardware is specified for its resistance to oxidation and its compatibility with passivation requirements. The hex body shape allows a wrench or hex driver to hold the standoff body while torquing the mating fastener, making it practical in confined panel spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-male configuration with M4 x 0.7 threads on both ends for board-to-board or board-to-chassis stacking\u003c\/li\u003e\n  \u003cli\u003e20 mm overall length with length tolerance of -0.15 mm to +0.15 mm for precise board spacing\u003c\/li\u003e\n  \u003cli\u003e8 mm width across flats hex body accepts standard wrench or hex driver tooling\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 303 stainless steel construction with passivated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 federal specification for stainless steel fasteners\u003c\/li\u003e\n  \u003cli\u003eThread lengths of 8.5 mm, 9.0 mm, and 9.5 mm provide engagement flexibility\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 assemblies requiring M4 x 0.7 male-male hex standoffs with a 20 mm body length in stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a wrench or hex driver sized to the 8 mm width across flats to prevent body rotation during thread engagement. Power down and de-energize any circuit board or panel assembly completely before installing or removing board-level hardware. Avoid over-torquing threaded studs into PCB inserts, as stainless steel fasteners in metal inserts can gall if lubrication is not applied. Follow applicable enclosure and PCB assembly documentation for required standoff torque ranges and spacing specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Male\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\u003eOverall Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 8.5 mm, 9.0 mm, 9.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.15 mm to +0.15 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: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel, Grade 18-8 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\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: 0.18 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: MMX1635M09-MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728775414066,"sku":"MMX1635M09-MSC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84357611908f27e2258afcb9d4da0d3c_be570f0e-3e5f-412c-8c95-fd23111ceca7.jpg?v=1788696099","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmx1635m09-msc-hex-board-standoff-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
