Electro Hardware S1055-M07-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1055-M07-F16-I is a round, female unthreaded circuit board spacer designed to create a fixed standoff gap between a PCB and a mounting surface or between stacked boards. Machined from 18-8 and 303 grade stainless steel and left uncoated, this spacer meets the QQ-S-763 fastener standard. It accepts a number 10 screw, has an overall length of 0.125 inches, an inside diameter of 0.194 inches, and an outside diameter of 0.375 inches. Electricians, control board technicians, and electronics assembly professionals install these spacers to protect circuit boards from contact damage and to maintain consistent clearance during panel assembly.

This spacer is suited for use in control panels, HVAC control boards, electrical enclosures, and other applications requiring a compact, corrosion-resistant standoff. The 0.125-inch overall length makes it appropriate for installations with tight clearance requirements. Its stainless steel construction holds up in environments exposed to moisture, making it a practical choice for pool equipment panels, outdoor electrical enclosures, and similar trade installations where mild corrosion resistance is needed.

Installation Notes

This spacer is typically installed by electricians or electronics technicians during control board assembly or replacement. Power down and de-energize all circuits before working inside any panel or enclosure. Use appropriate hand tools to seat the spacer flush and confirm board clearance before reinstalling or energizing the assembly. Follow applicable NEC guidelines for panel and enclosure work.
