Electro Hardware S1127-M01-F21-J Circuit Board Spacer Brass

Product Description

The ELECTRO HARDWARE S1127-M01-F21-J is a round, female unthreaded circuit board spacer designed to create consistent standoff clearance between a PCB and a mounting surface. Machined from brass to ASTM B633 and QQ-B-626 Comp 22 Type 1 standards, the spacer carries a zinc-plated finish for corrosion resistance. It measures 1-1/4 inches overall length with a 0.219 inch inside diameter and a 0.375 inch outside diameter, sized to accept a Number 12 screw. Electricians, HVAC technicians, and electronics assembly professionals use this type of spacer during control board installations and panel builds.

This spacer fits residential and commercial applications wherever a printed circuit board requires a secure, properly spaced standoff from a chassis or mounting plate. Typical uses include control board mounting in HVAC equipment, electrical enclosures, and industrial panel assemblies. The brass construction and zinc-plated finish make it suitable for environments where light corrosion resistance is needed. Sold individually, it is appropriate for both field repair and new assembly work.

Key Features

• Female unthreaded body accepts a Number 12 screw for secure PCB standoff mounting
• Brass construction meets ASTM B633 and QQ-B-626 Comp 22 Type 1 fastener standards
• Zinc-plated finish provides corrosion resistance in enclosure environments
• 1-1/4 inch overall length with tight length tolerance of -0.005 to 0.005 inches
• 0.219 inch inside diameter with inside diameter tolerance of 0.000 to 0.010 inches
• Round body profile for consistent fitment in standard PCB mounting hole patterns

Compatibility

Designed as an OEM-style replacement or new-assembly component for circuit board mounting applications requiring a Number 12 screw, female unthreaded round spacer in inch measurements.

Installation Notes

Installation is performed by qualified electricians or electronics technicians. Always de-energize and lock out the equipment before removing or installing control boards or spacers. Use appropriately sized Number 12 fasteners to avoid stripping the unthreaded bore. Follow applicable NEC guidelines when working inside electrical enclosures or HVAC control panels.
