Electro Hardware S1111-M07-F16-J Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1111-M07-F16-J is a round, female unthreaded circuit board spacer machined from 18-8 Grade 303 stainless steel to QQ-S-763 fastener standard. It measures 1 inch overall length with a 0.375-inch outside diameter and a 0.219-inch inside diameter, sized for a 12 screw. The uncoated finish leaves the base stainless steel exposed, offering solid corrosion resistance without additional treatment. This spacer is installed by electronics assembly technicians, electricians, and HVAC controls technicians when mounting circuit boards to chassis, panels, or enclosures where consistent standoff height and secure fastener alignment are required.

This spacer is suited for use in control board assemblies, electrical enclosures, and panel-mount applications found in residential and commercial HVAC equipment, industrial controls, and general electronics assemblies. It accepts a 12 screw and provides a fixed 1-inch standoff to maintain clearance between a circuit board and the mounting surface. The female unthreaded bore allows a fastener to pass through and seat the board at a consistent height, which is important in vibration-prone or thermally cycled environments common in HVAC and mechanical controls installations.

Key Features

• 18-8 Grade 303 stainless steel construction meets QQ-S-763 fastener standard
• 1 inch overall length with tight length tolerance of -0.005 to 0.005 inches
• 0.219-inch inside diameter with bore tolerance of 0.000 to 0.010 inches for consistent 12 screw fit
• 0.375-inch outside diameter round body for compact footprint on circuit board layouts
• Female unthreaded design allows pass-through fastener mounting without thread engagement
• Uncoated finish preserves stainless steel corrosion resistance with no added coating thickness variables

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications requiring a 12 screw, 1-inch standoff in inch-measurement systems.

Installation Notes

Installation is performed by qualified electronics assembly technicians or licensed electricians working on control board enclosures. De-energize and lock out all power to the control panel before handling circuit boards or fasteners. Use appropriately sized 12 fasteners and standard hand tools; avoid over-torquing fasteners into the unthreaded bore, as this spacer is not threaded and relies on the fastener and mating hardware for clamping force. Follow applicable NEC guidelines when working inside electrical enclosures.
