Sized at 1.5 inches overall length with an inside diameter of 0.141 inches and an outside diameter of 0.3125 inches, this spacer accommodates a No. 6 screw thread. The body is machined from brass and finished with a zinc plating that meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards. It is installed by electronics technicians and field service technicians working on control boards in HVAC, electrical, and industrial panel applications.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and light commercial control board assemblies where consistent PCB standoff height is required. The female unthreaded bore allows a No. 6 fastener to pass through, making it compatible with standard PCB mounting patterns. Typical applications include mounting control boards in HVAC equipment, electrical enclosures, and equipment panels where vibration resistance and reliable board clearance are priorities. Its compact outside diameter of 0.3125 inches keeps board real estate usage minimal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded bore sized for No. 6 screw, inside diameter 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e1.5 inch overall length with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.3125 inch outside diameter with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eBrass construction with zinc plating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633, QQ-B-626 Comp 22 Type 1 fastener standards\u003c\/li\u003e\n  \u003cli\u003eRound body profile for consistent seating against PCB mounting surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style round circuit board spacer for No. 6 screw applications in standard inch-measurement PCB mounting configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by electronics or HVAC service technicians during control board replacement or new panel assembly. De-energize all circuits and discharge any capacitors before handling the control board. Use appropriately sized No. 6 fasteners to avoid damaging the unthreaded bore.
