Machined from brass and finished with zinc plating per ASTM B633, QQ-B-626 Comp 22 Type 1, this spacer accepts a No. 10 screw and measures 0.875 inches overall length with a 0.5-inch outside diameter and a 0.194-inch inside diameter. The zinc-plated finish provides corrosion resistance in panel and enclosure environments. Electricians, control panel builders, and electronics technicians install these spacers when assembling control boards, relay panels, and enclosure-mounted PCBs in HVAC, electrical, and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and commercial control panel assemblies, HVAC equipment circuit boards, and electrical enclosures where a No. 10 fastener is used to secure a board at a precise standoff height. The 0.875-inch overall length sets a consistent gap between the board and the mounting surface, preventing contact-related shorts and allowing airflow beneath the board. Its round body and standard inch dimensions make it a common fit for a wide range of panel assembly work across HVAC, plumbing controls, and electrical distribution equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish per ASTM B633, QQ-B-626 Comp 22 Type 1 for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore accepts No. 10 screw fasteners\u003c\/li\u003e\n  \u003cli\u003e0.875-inch overall length with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.5-inch outside diameter and 0.194-inch inside diameter with ID tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eRound body shape for consistent seating on flat mounting surfaces\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff spacer for circuit boards secured with No. 10 fasteners in standard inch-dimensioned panel assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCircuit board spacers are installed by electricians and control panel technicians. Always de-energize the panel or equipment completely before removing or installing any control board assembly. Use a properly sized No. 10 screw and do not overtighten, as brass spacers can deform under excessive torque. Verify standoff height requirements against the board manufacturer's specifications before selecting spacer length.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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-B-626 Comp 22 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: 0.875 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: 0.194 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\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\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: S1383-M01-F21-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740111012146,"sku":"S1383-M01-F21-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_7be9db18-b530-4151-8fb5-2c69bfad2bba.jpg?v=1788822382","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1383-m01-f21-i-circuit-board-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
