It measures 0.75 inches overall length with a 0.5 inch outside diameter and a 0.194 inch inside diameter. The uncoated finish and inch-system dimensions make it a straightforward, no-prep hardware component for PCB mounting applications. Electricians, electronics technicians, and control board assemblers use this type of spacer to maintain precise standoff clearance between a circuit board and a mounting surface or between stacked boards in a control enclosure.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for residential and commercial applications wherever a No. 10 screw is used to mount a circuit board. Common install scenarios include HVAC control boards, industrial enclosures, electrical panel subassemblies, and OEM equipment builds. Its round body shape and female unthreaded bore accept a No. 10 fastener passed through from the mounting surface, holding the PCB at a fixed, consistent standoff height across the assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded round body accepts No. 10 screw for straightforward PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003e0.75 inch overall length with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e0.194 inch inside diameter with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003e0.5 inch outside diameter for consistent, stable board support\u003c\/li\u003e\n\u003cli\u003eAluminum grade T-3, manufactured to QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no additional surface prep required before installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-system PCB standoff spacer for No. 10 screw applications in control board assemblies, electrical enclosures, and OEM equipment builds.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians or electronics technicians during control board assembly or field replacement. De-energize all circuits and verify zero voltage before handling any circuit board or its mounting hardware. Use appropriately sized hand tools and avoid over-torquing fasteners through the unthreaded bore, as the female bore is not tapped and relies on the mating fastener for retention. Follow applicable NEC guidelines when working inside energized enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eScrew Size\u003c\/strong\u003e: No. 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 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\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.194 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\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T-3\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: QQ-A-225A Comp 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: S1375-M04-F16-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744116179250,"sku":"S1375-M04-F16-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_b455af81-2a62-475e-83e4-8932193d90b0.jpg?v=1788854329","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1375-m04-f16-i-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
