Machined from brass and finished with a zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1, this spacer delivers corrosion resistance suitable for electronics assemblies in HVAC control panels, electrical enclosures, and similar trade equipment. It accepts a No. 2 screw, measures 0.625 inches in overall length, and has an inside diameter of 0.089 inches with an outside diameter of 0.1875 inches. The female unthreaded design allows a fastener to pass through or seat against it during board mounting.\u003c\/p\u003e\u003cp\u003eThis spacer is used wherever a No. 2 fastener is needed to stack or isolate a circuit board from a chassis or mounting plate. Typical applications include control board installations in residential and light commercial HVAC units, electrical enclosures, and industrial panel assemblies. The brass construction with zinc finish makes it suitable for environments where mild corrosion resistance is required. Electricians, HVAC technicians, and electronics assembly professionals commonly use this type of hardware during control board replacement or panel fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts No. 2 screws for straightforward board mounting\u003c\/li\u003e\n\u003cli\u003eBrass base material with zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.625 inches with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.089 inches with a tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003eRound body profile with 0.1875 inches outside diameter for compact footprint on dense PCB layouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with No. 2 fasteners in standard circuit board standoff applications across HVAC control panels, electrical enclosures, and electronics assemblies requiring a round brass spacer at this size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians or HVAC technicians during control board service or panel assembly. Always de-energize and lock out the equipment before working inside any electrical enclosure or control panel. Ensure the mating fastener is a No. 2 screw and that the board hole pattern aligns with the spacer inside diameter before seating. Avoid over-torquing fasteners against the unthreaded bore, as the spacer provides positional standoff only and is not intended to carry thread load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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. 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.625 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: 0.089 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\u003eOutside Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: S317M01F21C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51753884451122,"sku":"S317M01F21C","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_44607b97-33c2-4b6b-a580-ecf38b9b98df.jpg?v=1788941820","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s317m01f21c-round-pcb-spacer-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
