Machined from 303 stainless steel with a passivated finish per QQ-S-763, this standoff resists corrosion and maintains dimensional accuracy in demanding environments. The hex body measures 3\/16 inches across flats and 5\/16 inches in overall length. The male thread engages the lower board or chassis while the female thread accepts the fastener for the upper board. It is installed by electronics assembly technicians, field service engineers, and industrial maintenance electricians.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for circuit board assemblies in HVAC control panels, industrial enclosures, and electronics mounting applications where a secure, non-conductive-free metallic spacer is required. The 4-40 thread size is widely used in light-duty PCB stacking configurations. The passivated stainless steel construction makes it a reliable choice for environments exposed to moisture or mild chemical contact. Minimum order quantity is 10 pieces, sold as individual units per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e303 stainless steel construction with passivated finish per QQ-S-763 for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMale-female configuration allows PCB-to-PCB or PCB-to-chassis stacking\u003c\/li\u003e\n  \u003cli\u003e4-40 thread size on both male and female ends\u003c\/li\u003e\n  \u003cli\u003eOverall body length of 5\/16 inches (0.3125 inches) for precise board spacing\u003c\/li\u003e\n  \u003cli\u003eHex body at 3\/16 inches across flats allows wrench or nutdriver installation\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.005 to 0.005 inches ensures consistent stack height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 male-female hex standoff for use in circuit board assemblies requiring 5\/16-inch spacing.

Always de-energize and discharge the circuit board assembly before installing or removing standoffs. Avoid overtightening, which can strip the 4-40 threads or crack the PCB substrate. Follow applicable assembly standards for torque guidelines specific to your board material and application.\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: 5\/16 inches (0.3125 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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/16 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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\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: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: 1307M09F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51738488930610,"sku":"1307M09F16440","price":50.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2ed038b6de2684c05119d308ef78b1d_edb65a54-a4a4-4031-81ee-062cb6e59262.jpg?v=1788800200","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1307m09f16440-hex-standoff-4-40-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
