Electro Hardware S1127-M07-F16-J Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1127-M07-F16-J is a round, female unthreaded circuit board spacer designed to create a fixed standoff between a printed circuit board and a mounting surface. Machined from 18-8 grade 303 stainless steel and left uncoated, it provides corrosion resistance in control board assemblies found in HVAC units, electrical enclosures, and industrial equipment. It accepts a No. 12 screw, measures 1.25 inches in overall length, and has an inside diameter of 0.219 inches with an outside diameter of 0.375 inches. Electricians, HVAC technicians, and controls installers use this spacer when mounting or replacing control boards that require consistent, rigid board standoff hardware.

This spacer is suited for residential and commercial applications wherever a No. 12-screw circuit board standoff is required. Typical install scenarios include control board replacements in furnaces, air handlers, condensing units, electrical panels, and other equipment enclosures where stainless steel hardware is specified for corrosion resistance or to meet fastener standards. It conforms to fastener standard QQ-S-763, making it appropriate for applications requiring documented material compliance. Sold individually, it can be sourced in the quantity needed for a specific job.

Key Features

• 18-8 grade 303 stainless steel construction for corrosion resistance in demanding environments
• Conforms to fastener standard QQ-S-763 for documented material compliance
• Female unthreaded bore accepts No. 12 screw with inside diameter of 0.219 inches
• Tight tolerances: inside diameter tolerance of 0.000 to 0.010 inches, length tolerance of -0.005 to 0.005 inches
• Uncoated finish eliminates coating thickness as a variable in precision assemblies
• Round body profile fits standard board-mounting layouts

Compatibility

Designed as a standard No. 12 screw circuit board spacer for use in any control board assembly or enclosure requiring a female unthreaded stainless steel standoff with a 1.25-inch overall length and 0.375-inch outside diameter.

Installation Notes

Installation is performed by electricians or HVAC technicians during control board mounting or replacement. Always de-energize and lock out the equipment before handling circuit boards or board-mounting hardware. Verify the mating screw size is No. 12 before assembly to prevent thread or bore damage. Ensure the mounting surface is clean and flat to maintain consistent board standoff height within the length tolerance.
