Electro Hardware S801-M07-F16-H Round Pcb Spacer No. 8

Product Description

The ELECTRO HARDWARE S801-M07-F16-H is a round, female unthreaded circuit board spacer designed to maintain precise standoff distance between a PCB and a mounting surface. Manufactured from 18-8 303 stainless steel with an uncoated finish, this spacer meets the QQ-S-763 fastener standard. It accepts a No. 8 screw and measures 0.375 inches overall length, with a 0.3125 inch outside diameter and a 0.171 inch inside diameter. Length tolerance is held to plus or minus 0.005 inches. Electricians, electronics technicians, and industrial maintenance professionals install this type of hardware during board mounting operations where corrosion resistance and dimensional consistency are required.

This spacer is suited for use in residential and commercial electrical assemblies, control panels, HVAC control boards, and other applications where a No. 8 fastener is used to secure a circuit board. Its stainless steel construction makes it appropriate for environments where moisture or mild chemical exposure is a concern. The female unthreaded design allows a screw to pass through freely, seating the board at a fixed standoff height without threading engagement at the spacer body itself.

Key Features

• 18-8 303 stainless steel construction meets QQ-S-763 fastener standard for corrosion resistance
• Female unthreaded body accepts No. 8 screws without threading engagement at the spacer
• Overall length of 0.375 inches with tight length tolerance of plus or minus 0.005 inches
• Inside diameter tolerance of 0.000 to 0.010 inches for consistent screw fit
• Uncoated finish maintains dimensional integrity and avoids coating thickness variability
• Round body shape for standard PCB standoff mounting layouts

Compatibility

Designed as a standard No. 8 screw round circuit board spacer for PCB mounting applications in control panels, HVAC boards, and general electrical assemblies requiring a 0.375 inch standoff height.

Installation Notes

Installation is performed by qualified electricians or electronics technicians following applicable NEC guidelines and equipment manufacturer procedures. De-energize all circuits and discharge any capacitors before handling circuit boards or installing spacers. Use appropriately sized No. 8 screws to avoid deforming the inside diameter. Inspect the mounting surface for flatness before seating to maintain consistent standoff height across all mounting points.
