Machined from 303 stainless steel with a passivated finish per QQ-S-763, this standoff resists corrosion and contamination in demanding environments. The hex body measures 3\/16 inches across flats, the overall body length is 7\/32 inches (0.2188 inches), and the thread size is 4-40. One end accepts a male 4-40 thread while the opposite end provides a female 4-40 threaded receive, allowing stackable or panel-mount configurations. Licensed electronics assembly technicians, board-level repair technicians, and trade professionals working on control boards in HVAC, electrical, and similar equipment use this type of hardware routinely.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for residential and light commercial control board assemblies, instrument panels, and enclosures where consistent PCB standoff height and electrical isolation are required. Typical applications include HVAC control board mounting, electrical enclosure PCB stacking, and any panel assembly calling for a 4-40 threaded hex standoff at the 7\/32-inch body length. The passivated stainless steel construction makes it appropriate for environments with moderate humidity or chemical exposure where plain steel or zinc-plated hardware is not adequate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex configuration allows secure PCB-to-panel or board-to-board standoff mounting\u003c\/li\u003e\n  \u003cli\u003e303 stainless steel construction with passivated finish per QQ-S-763 for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e4-40 thread size on both male and female ends for compatibility with standard 4-40 fastener systems\u003c\/li\u003e\n  \u003cli\u003eHex body profile (3\/16 inches across flats) allows wrench or nut driver installation and removal\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of plus or minus 0.005 inches ensures consistent stack height in multi-board assemblies\u003c\/li\u003e\n  \u003cli\u003eInch-system dimensions for straightforward integration into standard American fastener layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for circuit board assemblies using 4-40 threaded fasteners with a 7\/32-inch body length requirement.

Power down and de-energize any equipment completely before removing or installing circuit board standoffs. Use an appropriately sized hex nut driver or wrench sized for 3\/16-inch across-flats hardware to avoid rounding the hex body. Do not overtighten — apply only enough torque to seat the standoff flush without stressing the PCB substrate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\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: 7\/32 inches (0.2188 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\u003eThread Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth (Female End)\u003c\/strong\u003e: 1\/4 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: 303 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivated\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\u003eWeight\u003c\/strong\u003e: 0.12 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: 1304M09F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728561340722,"sku":"1304M09F16440","price":27.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_5e3fad3d-0316-4603-b4d0-82f1d2aada1e.jpg?v=1788693365","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1304m09f16440-hex-standoff-4-40-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
