Electro Hardware S1375-M07-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1375-M07-F16-H is a round, female unthreaded circuit board spacer designed to maintain precise standoff distances between PCBs and mounting surfaces. Machined from 18-8 Grade 303 stainless steel to QQ-S-763 specification, this spacer delivers corrosion resistance and dimensional consistency in demanding environments. It measures 0.75 inches overall length with a 0.5 inches outside diameter and a 0.171 inches inside diameter, accommodating a number 8 screw. The uncoated finish avoids interference with sensitive electronic assemblies. Electricians, electronics technicians, and control board installers use this type of spacer when mounting control boards in HVAC equipment, electrical panels, and industrial enclosures.

This spacer is suited for residential and commercial applications where circuit boards require secure, uniform standoff mounting. Typical install scenarios include HVAC control board replacements, relay panel assemblies, and industrial enclosure builds where stainless steel hardware is specified for corrosion resistance or code compliance. The number 8 thread size fits a wide range of standard PCB mounting configurations.

Key Features

• 18-8 Grade 303 stainless steel construction per QQ-S-763 specification for corrosion resistance
• Female unthreaded body accepts a number 8 screw for straightforward PCB mounting
• 0.75 inches overall length provides consistent standoff height across the board
• 0.5 inches outside diameter with round body for stable, flush seating on mounting surfaces
• Uncoated finish suitable for electrically sensitive or cleanroom-conscious assemblies
• Length tolerance of -0.005 to 0.005 inches ensures dimensional accuracy across installations

Compatibility

Designed as a standard number 8 screw-size round circuit board spacer for use in PCB mounting applications requiring a female unthreaded stainless steel standoff with 0.75 inches overall length.

Installation Notes

Installation is typically performed by electricians or electronics technicians. De-energize all circuits and discharge any capacitors before handling control boards or installing spacers in live panels. Use a calibrated torque driver appropriate for number 8 fasteners to avoid deforming the unthreaded female bore. Ensure the mounting surface is clean and flat to maintain the standoff height tolerance specified.
