The standoff features a 4-40 internal thread, a fully threaded body with a 5\/16-inch thread depth, and a hex body shape measuring 3\/16 inches across flats. Overall length is 5\/16 inches. Molded from nylon with a plain, uncoated finish, this fastener is lightweight, non-conductive, and corrosion-resistant. It is manufactured to MIL-P-17091B standards, making it suitable for applications where dimensional and material consistency is required. Electronics technicians, PCB assemblers, and field service professionals working on control boards across HVAC, electrical, and industrial equipment commonly use this part.\u003c\/p\u003e\u003cp\u003eThis standoff is used in PCB assemblies where boards must be secured at a defined height above a chassis or a secondary board. Typical applications include control board mounting in HVAC equipment, electrical enclosures, and light industrial electronics. Its nylon construction makes it appropriate for environments where electrical isolation between the board and mounting surface is required. The small footprint and 4-40 thread size make it compatible with fine-pitch board layouts common in residential and commercial control modules.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale 4-40 internal thread, fully threaded through the body\u003c\/li\u003e\n\u003cli\u003e5\/16-inch overall length and 5\/16-inch thread depth for consistent board standoff height\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex width across flats for standard hex driver installation\u003c\/li\u003e\n\u003cli\u003eNylon construction provides electrical isolation and corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePlain, uncoated finish with tensile strength of 16,500 psi\u003c\/li\u003e\n\u003cli\u003eManufactured to MIL-P-17091B fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for printed circuit board assemblies using 4-40 thread fasteners and requiring 5\/16-inch board-to-surface spacing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or field service professionals using a standard hex driver sized for 3\/16-inch across flats. Disconnect and de-energize all equipment before handling circuit boards or removing fasteners. Avoid over-torquing nylon standoffs, as the material is subject to thread stripping under excessive force. Follow applicable NEC guidelines when working inside electrical enclosures or control panels.\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: 4-40\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\u003eThread Depth\u003c\/strong\u003e: 5\/16 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\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, Bright\/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: -0.005 to 0.005 inches\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: 1 pound (package)\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: P297M19F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728684515634,"sku":"P297M19F16440","price":24.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39bacc6f7f8c417865b8b192a68f5025.jpg?v=1788694964","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p297m19f16440-hex-standoff-4-40-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
