Machined from brass and finished with a zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, this spacer provides corrosion resistance and dimensional stability in demanding electronic assembly environments. It measures 0.5 inches in overall length, 0.5 inches in outside diameter, and 0.171 inches in inside diameter, accepting a No. 8 screw. Electronics assembly technicians, panel builders, and HVAC control board service professionals commonly use spacers of this type during board mounting and replacement work.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and light commercial electronic control assemblies, including HVAC control boards, relay panels, and general PCB mounting applications. The female unthreaded design allows a No. 8 fastener to pass through, holding the board at a consistent standoff height. Its compact 0.5-inch length makes it appropriate for tight enclosure clearances where precise board-to-chassis spacing is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction with zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1 for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts No. 8 screw fasteners\u003c\/li\u003e\n  \u003cli\u003e0.5 inches overall length with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.171 inches inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eRound body profile for uniform standoff and stable board support\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for direct compatibility with standard imperial hardware\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 for circuit boards requiring a No. 8 screw, 0.5-inch round brass spacer in imperial-dimensioned electronic assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics assembly technicians or licensed HVAC and electrical service professionals. Always de-energize and discharge any control board or panel before handling circuit board hardware. Use the correct No. 8 fastener to avoid damaging the unthreaded bore.
