Electro Hardware S1063-M07-F16-G Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1063-M07-F16-G is a round, female unthreaded circuit board spacer machined from 18-8 Grade 303 stainless steel to fastener standard QQ-S-763. It measures 0.25 inches overall length, 0.375 inches outside diameter, and 0.141 inches inside diameter, making it a compact standoff for securing PCBs at a fixed height above a mounting surface. The uncoated finish leaves the base metal exposed, suitable for environments where corrosion resistance of 18-8 stainless is adequate. This spacer accepts a No. 6 screw and is sized for applications requiring precise board-to-surface clearance in electronic assemblies.

This spacer is used in residential and commercial electronic control board installations, including HVAC control panels, variable-speed drive assemblies, and similar low-voltage circuit board mounting applications. It is appropriate for any application requiring a small, dimensionally consistent standoff where a No. 6 fastener is used. Installers working on printed circuit board replacements or new-build panel assemblies will find this spacer a direct fit for standard No. 6 screw hole patterns.

Key Features

• Round body profile with female unthreaded bore for No. 6 screw fastening
• 18-8 Grade 303 stainless steel construction per QQ-S-763 fastener standard
• 0.25 inches overall length with a tight length tolerance of -0.005 to 0.005 inches
• 0.375 inches outside diameter and 0.141 inches inside diameter with ID tolerance of 0.000 to 0.010 inches
• Uncoated finish retains natural stainless corrosion resistance without added plating

Compatibility

Designed as an OEM-style mounting spacer for circuit board assemblies that use No. 6 screw hardware and require a 0.25-inch standoff height.

Installation Notes

Installation is performed by qualified electronics technicians or licensed electricians during control board mounting or replacement work. De-energize the equipment completely and verify zero voltage at the board before handling any circuit board hardware. Use hand tools sized for No. 6 fasteners and avoid overtightening, which can crack PCB mounting pads. Follow applicable NEC guidelines for low-voltage control wiring when reinstalling boards after spacer placement.
