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

Product Description

The ELECTRO HARDWARE S1375-M07-F16-K is a round, female unthreaded circuit board spacer manufactured from 18-8 grade 303 stainless steel. It is designed to create a fixed standoff distance between a circuit board and a mounting surface, maintaining clearance and preventing contact that could cause shorts or mechanical stress. With a 0.75-inch overall length, a 0.5-inch outside diameter, and a 0.257-inch inside diameter sized for a 1/4-inch screw, this spacer is a direct-fit hardware component for electronic and electromechanical assemblies. Technicians and assemblers working on control boards in HVAC, industrial, or electrical panel applications will find this a standard-duty standoff solution.

This spacer is suited for use in board-level assembly work where stainless steel corrosion resistance and dimensional consistency are required. Typical applications include mounting control boards inside HVAC equipment, electrical enclosures, and similar environments where the spacer must maintain a stable, repeatable standoff height. The female unthreaded body accepts a 1/4-inch screw pass-through, allowing a fastener to run through the spacer bore and secure the board at the correct offset distance from its mounting surface.

Key Features

• 18-8 grade 303 stainless steel construction provides corrosion resistance in humid or condensing environments
• Female unthreaded body with 0.257-inch ID accommodates a 1/4-inch screw
• 0.75-inch overall length with a tight length tolerance of -0.005 to 0.005 inches ensures consistent board standoff height
• 0.5-inch outside diameter with round body shape for standard clearance hole patterns
• Inside diameter tolerance of 0.000 to 0.010 inches for reliable screw fit
• Uncoated finish meets QQ-S-763 fastener standard

Compatibility

Designed as an OEM-style replacement or assembly hardware component for circuit board mounting applications requiring a 1/4-inch screw size female unthreaded round spacer in stainless steel.

Installation Notes

Circuit board spacers of this type are installed by electrical or electronics technicians during board mounting or replacement procedures. Always de-energize and lock out the equipment before working on any control board assembly. Use appropriate hand tools to seat fasteners through the spacer bore without overtightening, which can crack the board or distort the spacer. Follow applicable NEC guidelines when working inside electrical enclosures.
