Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable corrosion resistance and conductivity characteristics required in professional electronics work. The hexagonal body measures 3\/16 inches across flats and 3\/16 inches in overall length, with a 5\/32-inch thread length on each end. The 2-56 thread size suits fine-pitch PCB mounting applications. Electronics technicians, field service engineers, and assembly professionals install these standoffs during board-level work and enclosure builds.\u003c\/p\u003e\u003cp\u003eThis standoff is used in residential and commercial electronics assemblies where consistent board-to-board or board-to-chassis clearance is required. Typical applications include control board mounting in HVAC equipment, industrial control panels, and general PCB enclosure assemblies. The male-female configuration allows stacking multiple standoffs or terminating a fastener stack with a screw on one end and a mating female standoff on the other. The compact 3\/16-inch form factor suits tight enclosure layouts common in equipment control boards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female hex configuration for stackable PCB spacing applications\u003c\/li\u003e\n\u003cli\u003e2-56 thread size for fine-pitch circuit board mounting\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22\u003c\/li\u003e\n\u003cli\u003eHexagonal body shape for wrench engagement during installation and removal\u003c\/li\u003e\n\u003cli\u003e3\/16-inch overall length and 5\/32-inch thread length for compact board spacing\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches for consistent stack height\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 2-56 threaded PCB mounting applications requiring a male-female hex standoff with a 3\/16-inch body length and zinc-plated brass construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians and field service professionals using a hex driver or small wrench sized for 3\/16-inch flats. De-energize all equipment and discharge any stored electrical energy before servicing control boards or mounting hardware. Avoid over-torquing the 2-56 thread, as brass is softer than steel and threads can strip under excessive force. Follow applicable IPC assembly standards and equipment manufacturer guidelines for board mounting torque and spacing requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male-Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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\u003eThread Length\u003c\/strong\u003e: 5\/32 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: Brass\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\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: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1303M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51737484656946,"sku":"1303M03F21256","price":31.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_92ac852c-ae19-4031-be71-490cc392eac4.jpg?v=1788789109","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1303m03f21256-hex-standoff-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
