It features an M3 x 0.5 thread on both ends with an overall length of 20 mm and a hexagonal body that measures 6 mm across the flats. Made from Grade 2 steel with a zinc-plated finish, it meets the QQ-S-633 fastener standard. Electronics assembly technicians and electrical panel builders use this standoff to mechanically secure and space circuit boards in control panels, enclosures, and industrial equipment.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric-thread applications requiring a rigid, conductive, metal spacer between a circuit board and a mounting surface. Typical install scenarios include control board mounting inside HVAC equipment, VFD enclosures, and automation panels where consistent board spacing and secure mechanical attachment are required. The hex body allows installation and removal with a standard wrench or nut driver, making it practical for field service and bench assembly alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3 x 0.5 male thread on both ends for metric fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e20 mm overall length with a 6 mm hex body width across flats\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for reliable mechanical strength in panel applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in indoor enclosure environments\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-633 fastener standard\u003c\/li\u003e\n  \u003cli\u003eHex body profile accepts standard wrench or nut driver for fast installation and removal\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 mounting applications requiring M3 x 0.5 male-male thread configuration in control panels and electronic enclosures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or electricians during panel assembly or field service. De-energize all circuits in the enclosure before handling or replacing standoffs near live boards. A nut driver or open-end wrench sized to 6 mm across flats is the appropriate tool for torquing this standoff by hand to snug-fit without over-stressing the thread. Follow applicable NEC guidelines when working inside energized electrical enclosures.\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: M3 x 0.5\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: 5 mm to 6 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\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.150 mm to +0.150 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-S-633\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: 0.16 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: MMX1535M12-MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51737159663922,"sku":"MMX1535M12-MSC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84357611908f27e2258afcb9d4da0d3c_67ba9050-53c0-44dc-86d0-e26ecd20e897.jpg?v=1788785057","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmx1535m12-msc-hex-standoff-m3x0-5-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
