Sized at 0.125 inches overall length with a 0.171 inches inside diameter and 0.25 inches outside diameter, this spacer accepts a No. 8 screw and installs without threading into the body. Molded from Nylon Grade 101 per MIL-P-17091B and left uncoated, it resists corrosion and electrical conductivity concerns common with metal standoffs. Electronics assemblers and field technicians use these to secure control boards inside HVAC equipment, electrical enclosures, and other trade hardware.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and light commercial applications wherever a No. 8 fastener is used to mount a circuit board. Typical install scenarios include HVAC control board mounting, low-voltage panel assemblies, and general electronic enclosure builds where a non-conductive, precision-length standoff is required. The tight length tolerance of -0.005 to 0.005 inches ensures consistent board seating across a full assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded body accepts No. 8 screws without tapping\u003c\/li\u003e\n  \u003cli\u003eNylon Grade 101 construction per MIL-P-17091B — non-conductive and corrosion resistant\u003c\/li\u003e\n  \u003cli\u003e0.125 inches overall length with tight tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.171 inches with tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — no risk of coating contamination on PCB surfaces\u003c\/li\u003e\n  \u003cli\u003eRound body shape for consistent seating in standard board mounting holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for circuit board assemblies using No. 8 screw fasteners in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall by electronics assemblers or qualified technicians during control board service or replacement. Power down and de-energize the equipment fully before removing or installing any circuit board hardware. No special tools are required beyond a No. 8 fastener driver; do not overtighten, as the nylon body can deform under excess clamping load. Minimum order quantity for this part is 100 units.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.171 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.25 inches\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\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon Grade 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: S505M17F16H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728403530034,"sku":"S505M17F16H","price":795.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59e26cdbd9521312354e7345c3161837.jpg?v=1788690889","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s505m17f16h-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
