Machined from 303 stainless steel with a passivated finish per QQ-S-763, this standoff provides corrosion resistance suitable for demanding environments. The hex body measures 3\/16 inches across flats and delivers a 1-inch overall body length with a 4-40 threaded male post on one end and a 4-40 threaded female receptacle on the other. It is installed by electricians, electronics technicians, and field service professionals working on control boards in HVAC equipment, electrical panels, and industrial controls.\u003c\/p\u003e\u003cp\u003eThis standoff is used in residential and commercial electronic assemblies wherever a 4-40 thread size and 1-inch standoff height are required. Typical applications include mounting control boards, relay boards, and logic boards to chassis or DIN-rail subpanels. The male-female configuration allows multiple standoffs to be stacked or used as a single-tier spacer between a board and its mounting base. The passivated stainless finish makes it appropriate for environments with moderate moisture exposure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female thread configuration accepts 4-40 fasteners on both ends for versatile stacking or single-tier 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\u003eHex body profile allows wrench engagement for secure installation without slipping\u003c\/li\u003e\n\u003cli\u003e1-inch overall body length with 3\/16-inch thread length on the male end and 1\/4-inch thread depth on the female end\u003c\/li\u003e\n\u003cli\u003eLength tolerance held to plus or minus 0.005 inches for consistent board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for circuit board assemblies using 4-40 thread fasteners with a 1-inch standoff height requirement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified electronics or electrical technicians. De-energize all circuits and discharge any capacitors before handling circuit boards. Use a hex driver or small wrench sized for 3\/16-inch across flats to tighten the standoff without overtorquing the threaded engagement. Follow applicable NEC guidelines and equipment manufacturer instructions when servicing control board assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eOverall Body Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male End)\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female End)\u003c\/strong\u003e: 1\/4 inch\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, Grade 303\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: 0.17 pounds\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: 1329M09F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744820134194,"sku":"1329M09F16440","price":24.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_bfe9b045-1328-40ce-8843-cb5f7ad9527b.jpg?v=1788860944","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1329m09f16440-hex-standoff-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
