Built from brass and finished with zinc plating per ASTM B633 and QQ-B-626 Comp 22 Type 1, this spacer provides reliable electrical isolation and mechanical support between a PCB and its mounting surface. It accepts a Number 4 screw, measures 1.5 inches overall length, and carries a 0.116 inch inside diameter with a 0.1875 inch outside diameter. Licensed electricians, electronics technicians, and HVAC control board installers rely on this type of hardware when replacing or mounting control boards in residential and commercial equipment.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in control panel assemblies, HVAC control boards, relay panels, and general electronic enclosures where a fixed standoff distance of 1.5 inches is required. Its zinc-plated brass construction resists corrosion in light-duty indoor environments. The female unthreaded bore guides a Number 4 fastener without pre-tapping, making it straightforward to install in production and field-service scenarios alike. Sold individually, it is appropriate for single-board replacement work as well as small-volume repair jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass body with zinc plating meets ASTM B633 and QQ-B-626 Comp 22 Type 1 standards\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded design accepts Number 4 screws without tapping\u003c\/li\u003e\n  \u003cli\u003e1.5 inch overall length with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.116 inch inside diameter with tolerance of 0.000 to 0.010 inches for consistent fit\u003c\/li\u003e\n  \u003cli\u003eRound body profile for uniform load distribution on PCB mounting points\u003c\/li\u003e\n  \u003cli\u003eSold as individual unit with no minimum order quantity above one piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service spacer for circuit board mounting applications requiring a Number 4 screw, 1.5 inch standoff height, and 0.1875 inch outside diameter in inch-measurement fastener systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize and lock out all power to the equipment before removing or installing circuit board hardware. Use a screwdriver or nut driver appropriate for the Number 4 fastener being used with this spacer. Ensure the mating board holes align with the spacer bore before seating fasteners to avoid cracking the PCB.
