It measures 0.875 inches in overall length with a 0.5-inch outside diameter and a 0.171-inch inside diameter sized for a No. 8 screw. The uncoated finish leaves the aluminum in its natural state, suitable for most indoor electronic enclosure environments. Electricians, electronics technicians, and control-board service professionals install this spacer to maintain precise standoff distances between printed circuit boards and mounting surfaces or between stacked boards within enclosures.\u003c\/p\u003e\u003cp\u003eThis spacer is used wherever a No. 8 fastener is needed to secure or stack circuit boards in control panels, HVAC system boards, electrical enclosures, and similar assemblies. Its compact 0.5-inch outside diameter fits standard PCB mounting hole layouts without interfering with nearby components. The female unthreaded bore accepts a No. 8 screw passed through from the board side, making it a straightforward fit for typical panel-mount configurations in both residential and light commercial equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum T-3 grade construction per fastener standard QQ-A-225A Comp 2\u003c\/li\u003e\n\u003cli\u003e0.875-inch overall length with a length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e0.5-inch outside diameter with a 0.171-inch inside diameter for No. 8 screw clearance\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches for consistent fitment\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded, round body  -  no tapping required\u003c\/li\u003e\n\u003cli\u003eUncoated finish; no added plating or coating that could alter dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-inch-series circuit board spacer for No. 8 screw applications in PCB mounting, panel assembly, and electronic enclosure installations where a 0.875-inch standoff height and 0.5-inch outside diameter are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians or electronics technicians during board assembly or replacement. Power down and de-energize all circuits before working inside any control panel or enclosure. Use hand tools appropriate for No. 8 fasteners and avoid over-torquing, which can crack or deform the aluminum spacer body. Verify that the selected screw length accounts for the full 0.875-inch spacer height plus the board and mounting surface thicknesses.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eFastener Standard\u003c\/strong\u003e: QQ-A-225A Comp 2\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\u003eScrew Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.875 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: 0.171 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\u003eFinish\u003c\/strong\u003e: Uncoated\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: S1383-M04-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739711635762,"sku":"S1383-M04-F16-H","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_f0800b20-6073-4820-b542-d70d48bf8db4.jpg?v=1788818114","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1383-m04-f16-h-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
