Machined from 303 stainless steel with a bright uncoated finish, this standoff provides corrosion resistance and reliable thread engagement in high-cycle service environments. The male thread end is 2-56 with a 5\/32-inch thread length, and the female end accepts a 2-56 fastener with a 3\/16-inch thread depth. The hex body measures 3\/16 inches across flats, with an overall body length of 0.75 inches and a length tolerance of -0.005 to 0.005 inches. Licensed electricians, electronics technicians, and PCB assembly professionals install this fastener during board-level assembly and rework.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in circuit board assemblies requiring a secure, reusable threaded standoff in a compact form factor. Typical applications include stacking or mounting PCBs inside control enclosures, HVAC control boards, industrial panel assemblies, and similar equipment where vibration resistance and precise board spacing are required. The 303 stainless steel construction makes it appropriate for environments with moderate moisture exposure. It is sold and packaged as a single piece, meeting QQ-S-763 fastener standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female hex configuration for PCB stacking and panel mounting\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction per QQ-S-763 standard\u003c\/li\u003e\n\u003cli\u003e2-56 thread size on both male and female ends\u003c\/li\u003e\n\u003cli\u003e0.75-inch overall body length with tight length tolerance of plus or minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex width across flats for standard hex driver installation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for clean thread engagement without coating interference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 2-56 male-female hex standoff for use in circuit board assemblies and electronic panel applications requiring QQ-S-763 compliant stainless steel hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall with a 3\/16-inch hex driver or appropriately sized nutdriver. Ensure mating threads are clean and free of debris before engagement to avoid cross-threading the 2-56 threads. Power down and de-energize all assemblies before performing PCB mounting or standoff replacement work. Follow applicable IPC assembly standards and equipment manufacturer guidelines during installation.\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\u003eOverall Body Length\u003c\/strong\u003e: 0.75 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\u003eBody Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1321M09F16256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51730535186738,"sku":"1321M09F16256","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354e84e78593c87d91054c55b2ccfd1d_786ca4af-7818-47ad-a5d6-30763fae21c3.jpg?v=1788719166","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1321m09f16256-hex-standoff-2-56","provider":"Voomi Supply","version":"1.0","type":"link"}
