Machined from nylon with a plain, uncoated finish, this standoff is fully threaded to an M3 x 0.5 thread size across its entire 23 mm overall length. The hex body measures 4.5 mm width across flats, allowing standard hex tooling for secure installation. With a tensile strength of 16,500 psi, this nylon standoff offers reliable structural integrity in low-load electronic assemblies where non-conductive spacing hardware is required.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in PCB assembly, control panel fabrication, and electronic enclosure builds across a range of industries including HVAC controls, industrial automation, and electrical panel manufacturing. Its fully threaded female bore accepts M3 x 0.5 machine screws from both ends, making it a clean, stackable spacing solution for through-board and surface-mount applications. The nylon construction makes it appropriate where electrical isolation between mounting hardware and board traces is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFully threaded female bore — M3 x 0.5 thread size throughout entire 23 mm body length\u003c\/li\u003e\n\u003cli\u003eNylon material provides electrical isolation and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHex body profile (4.5 mm width across flats) accommodates standard hex drivers and wrenches\u003c\/li\u003e\n\u003cli\u003eTensile strength of 16,500 psi for reliable hold in light-duty PCB mounting applications\u003c\/li\u003e\n\u003cli\u003ePlain, uncoated finish — no coating to crack or flake in sensitive electronic environments\u003c\/li\u003e\n\u003cli\u003eMeets MIL-P-17091B fastener standard for mil-spec and industrial quality requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M3 x 0.5 machine screws in PCB standoff and spacer applications requiring a female hex nylon fastener conforming to MIL-P-17091B.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of circuit board standoffs is typically performed by electronics assembly technicians or licensed electricians during control board or panel fabrication. Power down all circuits completely before working on any PCB or control enclosure. Use an appropriately sized hex driver or nut driver matching the 4.5 mm across-flats dimension to avoid rounding the hex body. Do not overtighten — nylon fasteners have lower torque tolerance than metal hardware and can crack under excessive force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 23 mm (approximately 0.906 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 23 mm (fully threaded)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.5 mm (approximately 0.177 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: 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: Plain, uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTensile Strength\u003c\/strong\u003e: 16,500 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 mm to +0.13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: MIL-P-17091B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0001 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: MP445M19F16M3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51748686594354,"sku":"MP445M19F16M3","price":38.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6615e02289ce84fe730411915da9ccae_2cf6a417-61a1-4446-ba3d-8b2ae5870d0b.jpg?v=1788896719","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mp445m19f16m3-hex-standoff-m3-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
