Electro Hardware S1079-M04-F16-G Round Pcb Spacer No.6

Product Description

The ELECTRO HARDWARE S1079-M04-F16-G is a round, female unthreaded circuit board spacer machined from aluminum grade T-3 to QQ-A-225A Comp 2 specification. It measures 0.5 inches overall length (OAL) with a 0.375-inch outside diameter and a 0.141-inch inside diameter, sized to accept a No. 6 screw. The uncoated aluminum construction keeps weight low while offering adequate rigidity for PCB standoff applications. Electricians, electronics technicians, and HVAC controls installers use these spacers to maintain precise board-to-panel clearance and prevent grounding contact between circuit boards and metal enclosures.

This spacer is suited for residential and commercial electronics assemblies where a No. 6 fastener is used to mount a printed circuit board. Typical applications include control boards in HVAC equipment, electrical enclosures, and industrial control panels. Its round body and unthreaded female bore allow the board to seat flush at a fixed standoff height while a mating screw passes through from the board side. Minimum order quantity is 5 units; package quantity is 1.

Key Features

• Female unthreaded bore accepts No. 6 screws for straightforward PCB standoff installation
• 0.5-inch OAL with length tolerance of -0.005 to 0.005 inches for consistent board clearance
• 0.375-inch OD and 0.141-inch ID with inside diameter tolerance of 0.000 to 0.010 inches
• Aluminum grade T-3 construction per QQ-A-225A Comp 2 specification
• Uncoated finish - no coating thickness to account for in tight-clearance assemblies
• Round body shape for uniform load distribution around the mounting fastener

Compatibility

Designed for use in circuit board mounting applications requiring a No. 6 screw size, 0.5-inch standoff height, and a 0.375-inch round body profile in aluminum construction.

Installation Notes

Installation is performed by electronics technicians or electricians during control board assembly or replacement. Always de-energize the equipment and discharge any capacitors before handling circuit boards or installing standoff hardware. Use a correctly sized No. 6 fastener - do not force an oversized screw through the unthreaded bore, as this can crack the board or deform the spacer. Follow applicable NEC guidelines when working inside electrical enclosures.
