Electro Hardware S1423-M07-F16-H Round Board Spacer

Product Description

The ELECTRO HARDWARE S1423-M07-F16-H is a round, female unthreaded circuit board spacer designed to create a fixed standoff between a printed circuit board and a mounting surface. Built from 18-8 Grade 303 stainless steel with an uncoated finish, this spacer provides corrosion resistance and dimensional stability in electronic and electromechanical assemblies. It measures 1.5 inches overall length with a 0.171 inch inside diameter and a 0.5 inch outside diameter, sized for number 8 screw hardware. Electricians, HVAC technicians, and panel builders use these spacers when mounting control boards, relay panels, or interface boards that require precise separation from a chassis or enclosure floor.

This spacer is suited for residential and commercial applications wherever circuit boards are mounted inside electrical enclosures, HVAC control panels, or industrial equipment. The female unthreaded bore accepts a number 8 fastener and holds the board at a consistent standoff height. Its stainless steel construction makes it appropriate for environments with moderate moisture exposure or where ferrous hardware could accelerate corrosion on nearby components.

Key Features

• 18-8 Grade 303 stainless steel construction resists corrosion without a coating
• 1.5 inch overall length provides consistent board standoff height
• 0.171 inch inside diameter sized for number 8 screw fasteners
• 0.5 inch outside diameter in a round body profile
• Female unthreaded type for straightforward screw-through installation
• Meets fastener standard QQ-S-763

Compatibility

Designed as an OEM-style replacement or new-install spacer for circuit board mounting applications requiring a number 8 screw, female unthreaded, round standoff in inch dimensions.

Installation Notes

Installation is performed by electricians or electronics technicians as part of control board mounting procedures. Always de-energize and lock out the enclosure or panel before installing or replacing board spacers. Use the correct number 8 fastener length to avoid bottoming out in the spacer bore or over-compressing the board. Verify overall standoff height requirements against the board layout before final assembly.
