Electro Hardware S1407-M01-F21-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1407-M01-F21-I is a round, female unthreaded circuit board spacer designed for number 10 screw applications in electronic and electrical assemblies. Constructed from brass and finished with a zinc plating that meets ASTM B633, QQ-B-626 Comp 22 Type 1 standards, this spacer provides a corrosion-resistant standoff between a circuit board and a mounting surface. At 1.25 inches overall length with a 0.500 inch outside diameter and a 0.194 inch inside diameter, it is suited for applications requiring precise, consistent spacing in panel builds, control boards, and equipment enclosures. HVAC technicians, electricians, and electronics assembly professionals commonly use spacers of this type during control board installation and enclosure assembly work.

This spacer is appropriate for use in residential and light commercial electrical and electronic panel assemblies where a number 10 fastener is required. It is well-suited for control board mounting in HVAC equipment enclosures, electrical panels, and industrial equipment where brass construction and zinc plating are specified to meet corrosion resistance requirements. The female unthreaded bore accepts a number 10 screw and maintains consistent board standoff height during installation.

Installation Notes

Installation is typically performed by licensed electricians or electronics assembly technicians. Always de-energize and lock out the equipment before servicing any control board or enclosure. Use appropriately sized number 10 fasteners to avoid damage to the unthreaded bore. Follow applicable NEC guidelines and equipment manufacturer instructions when mounting or replacing circuit boards.
