Manufactured from Grade 2 steel with a zinc-plated finish meeting QQ-S-633 standards, this standoff delivers corrosion resistance suitable for indoor electronic assemblies. The fastener uses a 4-40 thread on both ends with a 3\/16 inch overall length and a hex body shape measuring 3\/16 inch across the flats. Electronics technicians and PCB assembly professionals install this type of hardware during board mounting and chassis assembly operations.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in residential and commercial electronic control assemblies, automation panels, and circuit board mounting applications where a 4-40 threaded male-to-male connection is required. The compact 3\/16 inch body length makes it appropriate for tight board-to-board or board-to-chassis spacing arrangements. It is sold individually and is compatible with standard 4-40 threaded hardware commonly found in electronic enclosures, control boards, and instrumentation assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-male thread configuration on both ends for board-to-chassis or board-to-board installation\u003c\/li\u003e\n  \u003cli\u003e4-40 thread size compatible with standard PCB mounting hardware\u003c\/li\u003e\n  \u003cli\u003eHex body shape allows installation and removal with standard nut drivers or hex wrenches\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction with zinc-plated finish meeting QQ-S-633 specification\u003c\/li\u003e\n  \u003cli\u003eCompact 3\/16 inch overall length for minimal stack height in tight assemblies\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.005 to 0.005 inches for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fastener for circuit board assemblies requiring 4-40 male-male hex standoffs with a 3\/16 inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or PCB assembly professionals. Power down and de-energize all circuits before working on any circuit board assembly. Use an appropriately sized nut driver or hex wrench matched to the 3\/16 inch width across flats to avoid rounding the hex body. Follow applicable IPC assembly standards and the equipment manufacturer's torque guidelines when fastening to sensitive PCB substrates.\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: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inches (0.1875 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: 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: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-633\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MM1305M12-MSC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51729451286834,"sku":"MM1305M12-MSC","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84357611908f27e2258afcb9d4da0d3c_f51bd4aa-bec9-4925-9135-0a085248f85f.jpg?v=1788704788","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mm1305m12-msc-hex-standoff-4-40-3-16in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
