It measures 0.625 inches overall length, 0.500 inches outside diameter, and 0.194 inches inside diameter, sized to accept a No. 10 screw. The zinc plating meets ASTM B633 and QQ-S-633 Type 1 standards, providing corrosion resistance in typical indoor enclosure environments. This type of spacer is installed by electricians, electronics technicians, and control board assemblers to maintain a fixed standoff distance between a printed circuit board and its mounting surface, preventing shorts and allowing airflow beneath the board.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in residential and commercial electrical panels, HVAC control board assemblies, industrial enclosures, and any application requiring a low-profile, round standoff for No. 10 fasteners. Its unthreaded female body accepts a No. 10 screw passed through the board from above, making it appropriate for through-bolt mounting configurations where consistent board standoff height is required across a flat mounting surface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts No. 10 screws for through-bolt circuit board mounting\u003c\/li\u003e\n\u003cli\u003e0.625 inch overall length provides consistent standoff height between board and mounting surface\u003c\/li\u003e\n\u003cli\u003e0.500 inch outside diameter and 0.194 inch inside diameter with tight tolerances for repeatable fit\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction with zinc plating per ASTM B633 and QQ-S-633 Type 1\u003c\/li\u003e\n\u003cli\u003eRound body shape suits standard circular mounting hole patterns on PCBs and enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series round circuit board spacer for No. 10 screw applications in electrical and electronic control board assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician or electronics technician. De-energize and lock out the equipment before servicing any control board or enclosure. Use hand tools to seat the spacer squarely against the mounting surface before driving the fastener to avoid racking or misaligning the board. Verify that the spacer height is consistent across all mounting points to prevent stress on the circuit board.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel Grade 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B633, QQ-S-633 Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: No. 10\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\u003eOverall Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.500 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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\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\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: S1367-M10-F21-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743272698162,"sku":"S1367-M10-F21-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_641056f1-00d3-494d-ad60-09080b8a682f.jpg?v=1788844848","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1367-m10-f21-i-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
