Electro Hardware S1087-M04-F16-J Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1087-M04-F16-J is a round, female unthreaded circuit board spacer machined from aluminum alloy grade T-3 to the QQ-A-225A Comp 2 fastener standard. It measures 0.625 inches overall length with a 0.375-inch outside diameter and a 0.219-inch inside diameter, sized for a No. 12 screw. The uncoated aluminum body provides a lightweight, corrosion-resistant standoff between a PCB and its mounting surface. Electricians, control technicians, and electronics assembly professionals use this spacer to maintain precise board-to-chassis clearance in control panels, HVAC circuit boards, and similar low-voltage enclosures.

This spacer is suited for use in residential and light commercial applications where a No. 12 fastener is used to mount circuit boards, relay panels, or control modules. Its inch-system dimensions make it a direct fit in standard domestic control enclosures. The female unthreaded bore accepts a No. 12 screw passed through from the board side, with the mating fastener threading into a separate standoff or chassis hole. It is sold and shipped individually.

Key Features

• Female unthreaded bore sized for No. 12 screw applications
• Aluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard
• 0.625-inch overall length with tight length tolerance of -0.005 to 0.005 inches
• Inside diameter tolerance of 0.000 to 0.010 inches for consistent screw fit
• Uncoated finish - no added coating to interfere with grounding or clearance
• Round body shape for standard PCB mounting hole patterns

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications requiring a No. 12 inch-system, female unthreaded round spacer.

Installation Notes

Installation is performed by electricians or control technicians during panel assembly or board replacement. Power down and de-energize the control panel completely before removing or installing circuit board hardware. Use appropriately sized hand tools to avoid distorting the aluminum body. Verify screw length accounts for the full 0.625-inch spacer stack to ensure proper board seating and clearance.
