Made from nylon (material grade 101) and left uncoated, this standoff accepts 4-40 threaded fasteners on both ends. The hex body measures 3\/16 inch across flats, with an overall body length of 1 inch and a thread depth of 1\/4 inch. It meets MIL-P-17091B standards and carries a tensile strength of 16,500 psi. The length tolerance is held to plus or minus 0.005 inch, making it suitable for precise PCB stacking applications.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in residential and commercial control boards, HVAC control panels, electrical enclosures, and other electronics assemblies where non-conductive spacing hardware is required. The nylon construction makes it appropriate for applications where electrical isolation between board layers is needed. Installers typically use this part when mounting circuit boards in furnace control panels, variable-frequency drives, relay panels, or similar equipment requiring repeatable board-to-board or board-to-chassis separation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex design accepts 4-40 threaded fasteners on both ends for stackable PCB mounting\u003c\/li\u003e\n  \u003cli\u003eNylon construction provides electrical isolation between mated surfaces\u003c\/li\u003e\n  \u003cli\u003eMeets MIL-P-17091B fastener standard for dimensional and material compliance\u003c\/li\u003e\n  \u003cli\u003eTensile strength of 16,500 psi supports secure board retention under vibration\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of plus or minus 0.005 inch ensures consistent PCB standoff height\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no metallic plating that could chip or contaminate board surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install nylon hex standoff for 4-40 threaded circuit board mounting applications in HVAC control panels, electrical enclosures, and general electronics assemblies requiring non-conductive hardware.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians, HVAC controls technicians, or electricians during control board replacement or panel assembly work. De-energize and lock out all power to the control panel before removing or installing circuit boards. Use a hex driver or nut driver sized for 3\/16 inch across flats to avoid stripping the nylon hex body — do not use pliers directly on the hex. Do not overtighten mating screws into the 4-40 female end, as nylon threads can be damaged by excessive torque.\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 Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus or minus 0.005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTensile Strength\u003c\/strong\u003e: 16,500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 101\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: MIL-P-17091B\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: 0.16 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: 1329M19F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51733231730994,"sku":"1329M19F16440","price":25.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3e9e766b006a012feeb0b88cd8ae549.jpg?v=1788753085","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1329m19f16440-hex-standoff-4-40-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
