Electro Hardware S873-M07-F16-G Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S873-M07-F16-G is a round, female unthreaded circuit board spacer designed to provide precise standoff clearance between a PCB and a mounting surface. Manufactured from 18-8 and 303 grade stainless steel with an uncoated finish, this spacer delivers corrosion resistance and dimensional consistency in both light-industrial and electronic assembly applications. It measures 1.5 inches overall length (OAL) with an inside diameter of 0.141 inches and an outside diameter of 0.3125 inches (5/16 inches), sized for a number 6 screw. Electricians, control board technicians, and electronics assembly professionals use this hardware when mounting circuit boards in HVAC control panels, electrical enclosures, and similar equipment.

This spacer is suited for use in residential and commercial control panel assemblies where a PCB must be held at a fixed distance from a chassis or backplate. Its round body and female unthreaded bore allow a number 6 fastener to pass through cleanly, providing secure, vibration-resistant board mounting in enclosures subject to normal operating conditions. Typical applications include HVAC control board installations, electrical panel component mounting, and industrial PCB assemblies where stainless steel hardware is specified for durability or corrosion resistance.

Key Features

• 18-8 and 303 grade stainless steel construction resists corrosion in demanding enclosure environments
• Female unthreaded bore accepts a number 6 screw for straightforward fastener compatibility
• 1.5-inch OAL provides consistent standoff height for reliable PCB clearance
• Uncoated finish maintains precise tolerances without added layer buildup
• Meets QQ-S-763 fastener standard for verified dimensional and material compliance
• Round body profile allows consistent seating and even load distribution on the board surface

Compatibility

Designed as a number 6 screw size, female unthreaded round spacer for circuit board mounting applications requiring a 1.5-inch standoff in inch-measurement assemblies.

Installation Notes

Installation is typically performed by electricians or electronics technicians during control board mounting or replacement procedures. De-energize and lock out the equipment before handling any circuit board hardware. Use the appropriately sized number 6 fastener and avoid over-torquing, as the unthreaded bore does not provide thread engagement to resist fastener stripping. Follow applicable NEC guidelines when working inside electrical enclosures.
