Machined from nylon with a plain, bright uncoated finish, this standoff accepts a 4-40 thread with a 1\/4 inch thread depth and measures 1.5 inches in overall length. The hexagonal body, 3\/16 inches across flats, allows for wrench engagement during installation without risking damage to adjacent board traces. It meets MIL-P-17091B fastener standards, making it suitable for defense, industrial, and commercial electronics applications where material grade 101 nylon is specified.\u003c\/p\u003e\n\u003cp\u003eThis standoff is used in circuit board assemblies where non-conductive spacing hardware is required. Common installation scenarios include mounting logic boards, relay boards, and control boards inside HVAC equipment, electrical panels, and industrial enclosures. The female-threaded design allows a mating screw or male standoff to thread into each end, stacking boards or securing them to a chassis at a fixed, repeatable distance. Installers working on control board replacement or panel builds will find this standoff appropriate for any application calling for a 4-40, nylon, hex-body female standoff at 1.5 inches OAL.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale 4-40 thread with 1\/4 inch thread depth on each end for secure board-to-board or board-to-chassis mounting\u003c\/li\u003e\n  \u003cli\u003e1.5 inch overall length provides consistent, measurable standoff distance between PCB layers or mounting surfaces\u003c\/li\u003e\n  \u003cli\u003eNylon construction provides electrical insulation and eliminates risk of shorting adjacent board traces\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex body width allows standard hex wrench or nut driver engagement without overtorque risk\u003c\/li\u003e\n  \u003cli\u003eMIL-P-17091B certified, material grade 101 nylon with a tensile strength of 16,500 psi\u003c\/li\u003e\n  \u003cli\u003ePlain, bright uncoated finish — no coatings to crack, flake, 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-installation hardware for any circuit board assembly requiring a female, hex-body, 4-40 threaded nylon standoff with 1.5 inch overall length and MIL-P-17091B compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNylon standoffs should be installed by hand or with a correctly sized hex driver to avoid stripping the threads — do not use impact tools. Power down and de-energize all circuits before removing or installing circuit board hardware. Follow applicable NEC guidelines and equipment manufacturer torque recommendations for PCB fasteners. Inspect threads for cross-threading before applying any torque, as nylon is more susceptible to thread damage than metal fasteners.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThread Depth\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eTensile Strength\u003c\/strong\u003e: 16,500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain, Bright\/Uncoated\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\u003eFastener Standard\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\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: P373M19F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51745154662706,"sku":"P373M19F16440","price":18.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90895277f23a2ea0c0720249564e7c33.jpg?v=1788863073","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p373m19f16440-hex-standoff-4-40-nylon","provider":"Voomi Supply","version":"1.0","type":"link"}
