Electro Hardware S1071-M04-F16-G Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1071-M04-F16-G is a round, female unthreaded circuit board spacer machined from aluminum alloy grade T3 to QQ-A-225A Comp 2 specification. It provides rigid, precise standoff distance between a printed circuit board and a mounting surface or stacked board assembly. The spacer measures 0.375 inches overall length with a 0.375-inch outside diameter and a 0.141-inch inside diameter, sized to accept a No. 6 fastener. The bright, uncoated finish leaves the aluminum bare for applications where coating would interfere with dimensional tolerance or conductivity requirements. Electronics technicians, HVAC control board installers, and electrical panel assemblers are the typical installers.

This spacer is suited for use in residential and light commercial applications wherever a circuit board requires a fixed standoff from a chassis or sub-panel. Common install scenarios include control board mounting in HVAC air handlers, furnace circuit boards, and general electronic enclosure assemblies. The No. 6 screw compatibility and inch-system dimensioning make it a straightforward fit for standard North American PCB mounting layouts. Sold individually, with a minimum order quantity of 5 units.

Key Features

• Aluminum grade T3, QQ-A-225A Comp 2 specification - consistent alloy quality for repeatable dimensional performance
• Female unthreaded bore accepts No. 6 fasteners - no tapping required
• 0.375-inch overall length with tight length tolerance of -0.005 to 0.005 inches - predictable board standoff height
• Inside diameter tolerance of 0.000 to 0.010 inches - reliable fastener fit
• Bright uncoated finish - no coating buildup to affect fit in close-tolerance applications
• Round body shape - compatible with standard PCB mounting hole patterns

Compatibility

Designed as a standard No. 6 screw, female unthreaded round circuit board spacer for inch-system PCB mounting applications in HVAC control assemblies, electrical enclosures, and general electronics fabrication.

Installation Notes

Installation is typically performed by electronics technicians or licensed HVAC technicians during control board replacement or enclosure assembly work. De-energize all circuits and discharge any capacitors before working on or near circuit boards. Use hand tools sized for No. 6 fasteners and avoid over-torquing, which can crack the board substrate or distort the spacer bore. Verify standoff height requirements against the board manufacturer's mounting specification before finalizing fastener length selection.
