Machined from 303-grade stainless steel with a passivated finish, this standoff meets QQ-S-763 federal specification for corrosion resistance and cleanliness. It features a 4-40 unified thread and a hexagonal body measuring 3\/16 inches across the flats and 3\/16 inches in body length. The male-female configuration allows standoffs to be stacked or used as a single spacer between a PCB and a mounting surface. Typically installed by electronics technicians, panel builders, and control board assemblers.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for use in control panels, HVAC circuit board assemblies, electrical enclosures, and other applications where a PCB must be elevated and mechanically secured away from a mounting surface. The compact 3\/16-inch overall length makes it appropriate for tight PCB stack spacing in residential and light commercial control board assemblies. The passivated stainless steel construction resists corrosion in environments where moisture or chemical exposure is a factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex body allows single-piece PCB standoff installation or stacked configurations\u003c\/li\u003e\n  \u003cli\u003e303-grade stainless steel construction with passivated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 federal specification for stainless steel fasteners\u003c\/li\u003e\n  \u003cli\u003e4-40 unified thread on both male and female ends\u003c\/li\u003e\n  \u003cli\u003eHex body shape allows installation and removal with standard hex drivers or wrenches\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of plus or minus 0.005 inches for consistent board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-40 threaded circuit board mounting holes in standard PCB assemblies requiring a 3\/16-inch standoff height.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electronics or panel assembly technician. De-energize all circuits before working on any control board or panel assembly. Use the appropriate hex driver or nut driver sized to the 3\/16-inch width across flats to avoid fastener damage. Do not overtighten, as stainless steel fasteners are susceptible to galling when excessive torque is applied without lubrication.\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\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\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 1\/4 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\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: Passivated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 1303M09F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51727360164146,"sku":"1303M09F16440","price":27.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/347c23de54de964d9dcf6bd1a7134370.jpg?v=1788676708","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1303m09f16440-hex-standoff-4-40-3-16-in-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
