Machined from brass to ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, this spacer receives a zinc-plated finish for corrosion resistance. It accepts a number 2 screw, measures 0.375 inches in overall length, 0.1875 inches in outside diameter, and 0.089 inches in inside diameter. Electricians, electronics technicians, and control board assemblers use this hardware when building or servicing low-voltage control assemblies, inverter boards, or industrial enclosures where precise board-to-chassis clearance is required.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for residential and commercial applications wherever a number 2 fastener is used to secure a circuit board. Typical install scenarios include HVAC control board mounting, electrical enclosure PCB assemblies, and industrial panel builds. The small outside diameter of 0.1875 inches makes it appropriate for densely populated boards where clearance between components is limited. It ships and is sold individually, with a minimum order quantity of one piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body accepts a number 2 screw for straightforward board-to-chassis mounting\u003c\/li\u003e\n  \u003cli\u003eBrass construction meets ASTM B633 and QQ-B-626 Comp 22 Type 1 fastener standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in control enclosure environments\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.375 inches with tight length tolerance of -0.005 to 0.005 inches for consistent standoff height\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.089 inches with tolerance of 0.000 to 0.010 inches for reliable screw fitment\u003c\/li\u003e\n  \u003cli\u003eCompact 0.1875 inches outside diameter suits high-density PCB layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-measurement circuit board spacer for use with number 2 screws in PCB mounting applications across residential and commercial control assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics technicians or electricians working on control board assemblies. De-energize and lock out the equipment before handling any PCB or its mounting hardware. Use appropriately sized hand tools and avoid overtightening into the female unthreaded body, as brass is softer than steel and may deform under excessive force. Follow applicable NEC guidelines when reassembling energized control panels or enclosures.\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: Number 2\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\u003eOutside Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.089 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\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  \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: S301M01F21C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731059867954,"sku":"S301M01F21C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_6b013f4e-96ad-46fa-b469-496a1cf0b08c.jpg?v=1788726401","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s301m01f21c-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
