Electro Hardware S1063-M04-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1063-M04-F16-H is a round, female unthreaded circuit board spacer manufactured from aluminum grade T-3 to fastener standard QQ-A-225A Comp 2. It measures 0.25 inches overall length with a 0.375 inches outside diameter and a 0.171 inches inside diameter, sized for a No. 8 screw. The spacer is supplied uncoated and serves to maintain a fixed standoff distance between a printed circuit board and its mounting surface. Electricians, HVAC technicians, and electronics maintenance technicians use this type of spacer during control board installations to provide mechanical clearance and reduce vibration contact between the board and chassis.

This spacer is suited for residential and light commercial applications where circuit boards must be mounted with a precise, consistent standoff. Typical install scenarios include HVAC control boards, industrial control panels, and general electronics enclosures where a No. 8 fastener pattern is used. The aluminum construction keeps weight low and provides corrosion resistance in typical indoor service environments. The uncoated finish is appropriate for applications where electrical isolation is not required at the spacer itself.

Key Features

• Female unthreaded design accepts No. 8 screws for straightforward board mounting
• 0.25 inches overall length provides a fixed standoff clearance between board and mounting surface
• 0.375 inches outside diameter and 0.171 inches inside diameter with a tight inside diameter tolerance of 0.000 to 0.010 inches
• Aluminum grade T-3 construction per fastener standard QQ-A-225A Comp 2
• Uncoated finish suitable for general indoor electronic and control board applications
• Length tolerance held to -0.005 to 0.005 inches for consistent stack-up in multi-spacer layouts

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications requiring a No. 8 screw size, round body, female unthreaded standoff in the 0.25 inch length range.

Installation Notes

Installation is typically performed by a licensed electrician or qualified HVAC technician during control board service or replacement. Power down and de-energize the control panel fully before removing or installing circuit board hardware. Use appropriately sized No. 8 fasteners and avoid overtightening, which can crack the board or deform the spacer. Follow applicable NEC guidelines when working inside electrical enclosures.
