Electro Hardware S1071-M04-F16-J Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1071-M04-F16-J is a round, female unthreaded aluminum circuit board spacer designed to maintain precise separation between printed circuit boards and mounting surfaces in electronic assemblies. Machined from aluminum grade T-3 to the QQ-A-225A Comp 2 fastener standard, this spacer measures 0.375 inches overall length, 0.375 inches outside diameter, and 0.219 inches inside diameter. The uncoated finish and tight length tolerance of -0.005 to 0.005 inches make it a reliable standoff component for HVAC control boards, electrical panels, and other trade electronics requiring consistent, repeatable board clearance.

This spacer is suited for residential and commercial electronic assemblies where a 12 screw size is used to mount or stack circuit boards. Typical applications include HVAC control board installations, electrical enclosure assemblies, and industrial equipment panels where aluminum standoffs are specified for lightweight, corrosion-resistant board support. The inside diameter tolerance of 0.000 to 0.010 inches accommodates standard 12 fasteners without slop or binding.

Key Features

• Female unthreaded round body accepts 12 screw hardware for secure board mounting
• 0.375-inch overall length provides consistent board-to-surface clearance
• Aluminum grade T-3 construction - lightweight and corrosion resistant
• Meets QQ-A-225A Comp 2 fastener standard for verified material compliance
• Tight length tolerance of -0.005 to 0.005 inches for precise stack height
• Uncoated finish - no coating thickness to account for in tight-clearance assemblies

Compatibility

Designed as a standard replacement or new-installation aluminum circuit board spacer for 12 screw applications in electronic assemblies requiring a 0.375-inch standoff height.

Installation Notes

Installation is typically performed by licensed electricians or qualified electronics assembly technicians. De-energize all circuits and discharge any capacitors before handling control boards or installing standoffs in live panels. Use appropriate hand tools for the 12 fastener size and verify board clearance after installation to ensure no component contact with the mounting surface. Follow applicable NEC guidelines when installing or replacing control boards in electrical enclosures.
