Molded from Nylon Grade 101 and left uncoated with a bright finish, this spacer provides reliable board standoff and mechanical isolation between PCB layers or between a board and a mounting surface. It measures 10 mm (0.394 inches) overall length with a 6 mm (0.236 inches) outside diameter and an inside diameter ranging from 3.2 mm to 3.6 mm (0.126 to 0.142 inches). Manufactured to MIL-P-17091B fastener standard, it suits applications where a lightweight, non-conductive spacer is required.\u003c\/p\u003e\u003cp\u003eThis spacer is used in electronics assembly, control board mounting, and panel fabrication across HVAC, electrical, and industrial equipment. Typical applications include mounting circuit boards in control enclosures, creating standoff clearance between stacked PCBs, and securing boards away from metal chassis surfaces to prevent shorts. The female unthreaded design accepts an M3 screw passed through from the mounting surface side. It is appropriate for both original equipment assembly and field repair or board replacement work performed by electronics technicians and controls specialists.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon Grade 101 construction provides electrical isolation and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded body accepts M3 screws without tapping\u003c\/li\u003e\n\u003cli\u003e10 mm overall length with tight length tolerance of -0.13 mm to +0.13 mm\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of 0.000 to 0.270 mm for consistent M3 screw fit\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish — no coating to crack, flake, or add dimensional variation\u003c\/li\u003e\n\u003cli\u003eMeets MIL-P-17091B fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in circuit board assemblies requiring an M3 screw size with a round, female unthreaded standoff spacer in a metric measurement system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed with the circuit board fully de-energized and any associated power supply disconnected before handling or repositioning boards. Use the appropriate M3 screw driver or bit to avoid stripping the mating fastener. Verify that the spacer inside diameter accommodates the specific M3 fastener shank tolerance before final assembly. Handle nylon spacers carefully to avoid deformation from overtightening, which can crack the body and reduce standoff effectiveness.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon Grade 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Thread Size\u003c\/strong\u003e: M3\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: 10 mm (0.394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6 mm (0.236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.2 to 3.6 mm (0.126 to 0.142 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.270 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.130 to 0.130 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated \/ Bright\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: MS1019M17F16D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51732940128562,"sku":"MS1019M17F16D","price":19.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06936a45222bfe113cd912c31d9eddab_8c86af47-cc3c-4990-a6aa-de4911e136ea.jpg?v=1788749195","url":"https:\/\/voomisupply.com\/products\/electro-hardware-ms1019m17f16d-round-board-spacer-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
