Electro Hardware S1067-M10-F21-G Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1067-M10-F21-G is a round, female unthreaded circuit board spacer designed to create precise standoff clearance between a PCB and a mounting surface. Built for Number 6 screw applications, this spacer measures 0.3125 inches overall length with an inside diameter of 0.141 inches and an outside diameter of 0.375 inches. Constructed from Grade 2 steel with a zinc-plated finish per ASTM B633 and QQ-S-633 Type 1, it delivers corrosion resistance suitable for electronics assembly and control board mounting in HVAC, electrical, and industrial panel applications. Electricians, electronics technicians, and panel builders use this hardware when installing or servicing control boards that require consistent standoff height and secure fastening.

This spacer is suited for residential and light commercial control board installations where Number 6 hardware is standard. Typical applications include furnace control boards, thermostat sub-bases, relay panels, and other electronic assemblies mounted inside HVAC equipment enclosures or electrical panels. The female unthreaded body accepts a Number 6 screw passed through from the PCB side, providing a clean, low-profile standoff without threading into the spacer body itself.

Key Features

• Female unthreaded round body accepts Number 6 screws for straightforward PCB standoff installation
• Overall length of 0.3125 inches with a tight length tolerance of -0.005 to 0.005 inches for consistent stack height
• Inside diameter of 0.141 inches with a tolerance of 0.000 to 0.010 inches
• Outside diameter of 0.375 inches for stable surface contact
• Grade 2 steel construction with zinc-plated finish meeting ASTM B633 and QQ-S-633 Type 1 standards
• Inch measurement system; sold individually

Compatibility

Designed as a standard Number 6 screw round circuit board spacer for use in PCB mounting applications requiring a female unthreaded standoff in the inch measurement system.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians during control board assembly or replacement. De-energize all circuits and follow applicable NEC guidelines before servicing any panel or control board. Use a correctly sized Number 6 screw to avoid stripping or misaligning the spacer. Verify standoff height requirements against the PCB manufacturer specifications before selecting spacer quantity and placement.
