Electro Hardware S1071-M07-F16-H Round Board Spacer 8

Product Description

The ELECTRO HARDWARE S1071-M07-F16-H is a round, female unthreaded circuit board spacer designed to maintain precise standoff distance between a PCB and a mounting surface. Constructed from 18-8 Grade 303 stainless steel and left uncoated, this spacer meets the QQ-S-763 fastener standard. It accepts a Number 8 screw and measures 0.375 inches in overall length, 0.375 inches in outside diameter, and 0.171 inches in inside diameter. Electricians, electronics technicians, and HVAC control board service techs use this type of spacer when mounting or replacing circuit boards in enclosures, control panels, and equipment cabinets.

This spacer is suited for residential and commercial applications wherever a Number 8 fastener is used to mount a circuit board to a chassis, DIN rail plate, or enclosure backpanel. Its stainless steel construction makes it appropriate for environments with moderate moisture exposure or where corrosion resistance is required. The female unthreaded bore accepts the screw shaft and provides a fixed, repeatable standoff height of 0.375 inches between the board and its mounting surface.

Key Features

• 18-8 Grade 303 stainless steel construction meets QQ-S-763 fastener standard
• Female unthreaded bore sized for Number 8 screw fasteners
• Uncoated finish — no added plating to affect dimensional tolerances
• Tight length tolerance of -0.005 to 0.005 inches for consistent board standoff height
• Inside diameter tolerance of 0.000 to 0.010 inches for reliable screw fit
• Round body shape for straightforward installation in standard PCB mounting holes

Compatibility

Designed as a standard Number 8 screw circuit board spacer for use in PCB mounting applications requiring a 0.375-inch standoff height in control panels, enclosures, and equipment cabinets.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians. Always de-energize the equipment and verify the absence of voltage before handling circuit boards or installing spacers. Use insulated hand tools when working inside energized enclosures is unavoidable, and follow applicable NEC guidelines for work within control panels. Do not overtighten the mating screw, as stainless fasteners are susceptible to galling.
