Electro Hardware S825-MO4-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S825-MO4-F16-I is a round, female unthreaded circuit board spacer machined from aluminum to precise dimensional tolerances. It measures 0.75 inches in overall length with a 0.3125-inch outside diameter and a 0.194-inch inside diameter sized for a 10 screw. The body is uncoated aluminum conforming to material grade T-3 and fastener standard QQ-A-225A Comp 2. This type of spacer is installed by electronics technicians, electrical contractors, and HVAC controls technicians to create consistent standoff clearance between a PCB and a mounting surface, protecting circuit traces from contact and allowing airflow beneath the board.

This spacer is suited for residential and commercial control board assemblies, HVAC equipment circuit boards, and general electronics panel work wherever a 10 screw pattern is used. Its female unthreaded bore accepts a mating fastener passed through from the board side, making it a straightforward fit in standard standoff applications. The uncoated aluminum finish is appropriate for indoor enclosure environments where corrosion exposure is minimal.

Key Features

• Female unthreaded bore sized for 10 screw, 0.194-inch inside diameter
• 0.75-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
• Aluminum grade T-3 construction per fastener standard QQ-A-225A Comp 2
• Round body profile for consistent standoff seating on flat panel surfaces
• Sold individually, no minimum order beyond single unit

Compatibility

Designed for use in circuit board standoff applications requiring a 10 screw size, 0.75-inch OAL, and a 0.3125-inch OD round aluminum spacer in inch-measurement systems.

Installation Notes

Installation is performed by qualified electricians or electronics technicians. De-energize the equipment completely before handling any circuit board assembly. Align the spacer between the board and mounting surface before seating the fastener to avoid cracking the PCB substrate. Follow applicable NEC guidelines for control panel assembly and board mounting clearances.
