Electro Hardware S341M04F16E Circuit Board Spacer Aluminum

Product Description

The ELECTRO HARDWARE S341M04F16E is a round, female unthreaded circuit board spacer machined from aluminum grade T3 to QQ-A-225A Comp 2 specification. It accepts a No. 4 screw and provides a 1 inch overall length, creating a precise standoff between a PCB and a mounting surface or between stacked boards. The inside diameter is 0.116 inches with a tolerance of 0.000 to 0.010 inches, and the outside diameter is 0.1875 inches. The uncoated bright finish is suitable for general electronic assembly environments. This spacer is installed by electronics technicians, field service engineers, and trade professionals performing control board replacements or panel assemblies.

This spacer is used wherever a circuit board must be held at a fixed, precise standoff distance from a chassis, enclosure floor, or secondary board. Common applications include HVAC control board assemblies, electrical panel subassemblies, and industrial equipment PCB mounting. The female unthreaded body accepts a No. 4 fastener passed through from the mounting surface, making it straightforward to integrate into standard PCB layouts. Its aluminum construction keeps the assembly lightweight while providing adequate rigidity for vibration-prone environments such as air handler units or rooftop equipment control enclosures.

Compatibility

Designed as a standard-dimension No. 4 screw round circuit board spacer suitable for PCB standoff applications in electronic control assemblies where a 1 inch female unthreaded aluminum spacer is specified.

Installation Notes

Installation is performed by electronics technicians or qualified trade professionals assembling or servicing control boards. De-energize and lock out all power to the control panel or equipment before removing or installing circuit board hardware. Use the correct No. 4 fastener and avoid overtightening, as excess torque can crack the PCB or deform the spacer bore. Follow applicable worksite electrical safety procedures and any equipment manufacturer assembly guidelines when replacing control board mounting hardware.
