Machined from brass and finished with zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1, this spacer provides corrosion resistance and reliable dimensional stability under repeated thermal cycling. It has an overall length of 0.375 inches, an inside diameter of 0.171 inches, and an outside diameter of 0.375 inches, sized to accept a No. 8 screw. HVAC control board assemblies, electrical enclosures, and pool equipment panels are common installation environments.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and light commercial applications wherever circuit boards require secure standoff mounting. It is installed by electricians, HVAC technicians, and electronics assembly professionals during control board replacement or panel assembly work. The female unthreaded body accepts a No. 8 fastener passed through from the board side, holding the PCB at a consistent height above the mounting plane to prevent short circuits and allow airflow beneath the board.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction with zinc-plated finish meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts No. 8 screws for straightforward PCB standoff mounting\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.375 inches with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.171 inches with an inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eRound body profile for consistent fitment in standard PCB standoff hole patterns\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides corrosion resistance in enclosure and panel environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or assembly component for circuit board standoff applications requiring a No. 8 screw, 0.375-inch overall length, and 0.375-inch outside diameter in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and de-energize the control board assembly and any associated equipment before removing or installing circuit board spacers. Use appropriate non-marring tools to seat the spacer without deforming the zinc-plated finish. Follow applicable NEC guidelines when working inside electrical enclosures. Verify spacer length and inside diameter match the existing standoff specification before installation to maintain proper PCB clearance.\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\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: 0.375 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\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\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: S1071-M01-F21-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744450707762,"sku":"S1071-M01-F21-H","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f22493c2131f1054fcc28f1c88e74699.jpg?v=1788856694","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1071-m01-f21-h-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
