Manufactured from Nylon Grade 101 and compliant with MIL-P-17091B, this metric spacer is sized for M4 fasteners and features an overall length of 21 millimeters, an outside diameter of 6 millimeters, and an inside diameter ranging from 4.2 to 4.8 millimeters. The uncoated finish and nylon construction make it electrically non-conductive, which is an important characteristic when isolating circuit boards from grounded chassis panels or enclosures.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used in electronic control panel assemblies, HVAC control boards, electrical enclosures, and similar applications where board standoff and mechanical support are required. It is appropriate for both residential and light commercial equipment builds and field repairs where M4 metric hardware is specified. Technicians working on control board replacements or panel upgrades will find this spacer useful for maintaining original board standoff heights during reinstallation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon Grade 101 construction provides electrical insulation and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMIL-P-17091B compliant for documented material and dimensional standards\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts M4 screws for straightforward installation\u003c\/li\u003e\n  \u003cli\u003e21 millimeter overall length with tight length tolerance of -0.13 to 0.13 millimeters\u003c\/li\u003e\n  \u003cli\u003e6 millimeter outside diameter with inside diameter range of 4.2 to 4.8 millimeters\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish — no additional coatings to affect dimensional fit or conductivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M4 metric fasteners in circuit board standoff applications.

These spacers are installed by electronics technicians, HVAC controls technicians, and electricians during board mounting or panel assembly. Use appropriate M4 metric screws and ensure spacers are seated flush and perpendicular to the board surface to prevent stress on PCB mounting holes. Do not overtighten fasteners through nylon spacers, as the material can deform under excessive clamping load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon Grade 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: MIL-P-17091B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 21 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.13 to 0.13 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.2 to 4.8 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.270 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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\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: MS1041M17F16F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51754491052338,"sku":"MS1041M17F16F","price":22.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06936a45222bfe113cd912c31d9eddab_9ad98f37-f8f3-4052-8ed1-4c46abeb73a8.jpg?v=1788945949","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1041m17f16f-circuit-board-spacer-m4","provider":"Voomi Supply","version":"1.0","type":"link"}
