Machined from brass with a zinc plating finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides corrosion resistance and reliable electrical isolation in electronic assemblies. The hexagonal body measures 3\/16 inches across flats, the overall body length is 15\/32 inches (0.4688 inches), and the thread size is 2-56. Electronics assemblers, electrical technicians, and board-level service professionals install these fasteners during PCB mounting and rework operations.\u003c\/p\u003e\u003cp\u003eThis standoff is used in circuit board assemblies where a male threaded stud on one end engages an adjacent board or chassis while the female threaded bore on the opposite end accepts a mating screw. Typical applications include control boards in HVAC equipment, industrial electronics enclosures, and general electronic assemblies requiring a stacked or elevated board configuration. The 2-56 thread size targets fine-pitch PCB mounting scenarios common in compact control electronics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female hex body allows stacking or standoff mounting with standard 2-56 fasteners\u003c\/li\u003e\n\u003cli\u003eBrass construction with zinc plating meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards\u003c\/li\u003e\n\u003cli\u003eHexagonal body shape allows wrench engagement for controlled installation torque\u003c\/li\u003e\n\u003cli\u003eOverall body length of 15\/32 inches (0.4688 inches) provides consistent board-to-board or board-to-chassis spacing\u003c\/li\u003e\n\u003cli\u003eThread depth of 3\/16 inches on the female end and thread length of 5\/32 inches on the male end\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches supports precise stacking in tight assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation hardware for circuit board assemblies using 2-56 inch-series thread fasteners in hex standoff configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or licensed electricians during board assembly or rework. Always de-energize and discharge any boards or assemblies before handling. Use an appropriately sized hex wrench or nutdriver on the hex body to seat the standoff without over-stressing the PCB substrate. Follow applicable assembly workmanship standards and ESD precautions when working with populated circuit boards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Body Length\u003c\/strong\u003e: 0.4688 inches (15\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 3\/16 inches\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\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: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 1312M03F21256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51735498752306,"sku":"1312M03F21256","price":31.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_13096bc3-60d9-4647-9af9-7b1226568e12.jpg?v=1788772738","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1312m03f21256-hex-standoff-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
