Electro Hardware S817-M07-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S817-M07-F16-I is a round, female unthreaded circuit board spacer machined from 18-8 and 303 grade stainless steel to meet QQ-S-763 fastener standards. It measures 0.625 inches overall length with a 0.3125-inch outside diameter and a 0.194-inch inside diameter, sized for number 10 screw applications. The uncoated finish leaves the base stainless steel exposed, relying on the inherent corrosion resistance of 18-8 and 303 alloys. Electrical and electronics technicians use these spacers to maintain precise standoff distances between a circuit board and a mounting surface, preventing shorts and allowing airflow beneath the board.

This spacer is suited for use in electronic control board assemblies found in HVAC equipment, industrial controls, and other panel-mounted electronic applications. The female unthreaded design accepts a number 10 fastener passed through the spacer bore, making it compatible with standard PCB mounting hardware. Its small footprint and round body shape fit tight board layouts where space between mounting points is limited. The stainless steel construction holds up in environments where mild corrosion exposure or elevated humidity is a concern.

Key Features

• 18-8 and 303 grade stainless steel construction meeting QQ-S-763 fastener standard
• Female unthreaded bore sized for number 10 screw clearance
• 0.625-inch overall length with tight length tolerance of -0.005 to 0.005 inches
• 0.3125-inch outside diameter with inside diameter tolerance of 0.000 to 0.010 inches
• Uncoated finish preserves natural stainless corrosion resistance
• Round body shape for consistent, predictable fitment in PCB standoff applications

Compatibility

Designed as an OEM-style replacement or standard-use circuit board spacer for number 10 screw PCB mounting applications in residential and commercial electronic control assemblies.

Installation Notes

Installation is performed by electricians or electronics technicians working on control board assemblies. Always de-energize the equipment and discharge any stored electrical energy before handling circuit boards or mounting hardware. Use appropriate hand tools sized for number 10 fasteners and avoid over-torquing, which can crack the PCB substrate. Follow applicable NEC guidelines when working on electrical control panels.
