Electro Hardware S1367-M04-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1367-M04-F16-H is a round, female unthreaded circuit board spacer machined from aluminum grade T-3 per fastener standard QQ-A-225A Comp 2. It measures 0.625 inches overall length with a 0.5 inch outside diameter and a 0.171 inch inside diameter, sized to accept a No. 8 screw. The uncoated finish leaves the aluminum bare for applications where coating would interfere with fit or conductivity. Electrical and electronics technicians use these spacers to maintain precise standoff distances between circuit boards and mounting surfaces, preventing contact shorts and allowing airflow under the board.

This spacer is suited for use in control board assemblies, panel wiring enclosures, and electronic equipment found in HVAC systems, electrical control panels, and similar trade-installed equipment. Its compact 0.5 inch OD and 0.625 inch length make it appropriate for tight PCB layouts where space between mounting points is limited. The female unthreaded body accepts a No. 8 fastener through the board stack, providing a clean, repeatable standoff height without additional hardware modification.

Key Features

• Aluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard
• Female unthreaded body accepts No. 8 screw for straightforward board mounting
• 0.625 inch overall length with tight length tolerance of -0.005 to 0.005 inches
• 0.171 inch inside diameter with ID tolerance of 0.000 to 0.010 inches
• Round body shape with 0.5 inch outside diameter for compact PCB footprint
• Uncoated finish - no secondary processing required before installation

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board assemblies requiring a No. 8 screw, female unthreaded round standoff with a 0.625 inch standoff height.

Installation Notes

Installation is performed by electricians or electronics technicians during control board assembly or replacement. Power down and de-energize the panel or equipment completely before handling circuit boards or mounting hardware. Use calibrated hand tools to seat fasteners without over-torquing, which can crack PCB mounting holes. Follow applicable NEC guidelines for panel and enclosure work.
