Electro Hardware S1383-M07-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1383-M07-F16-I is a round, female unthreaded circuit board spacer designed to maintain precise standoff distances between a PCB and a mounting surface or between stacked boards. Manufactured from 18-8 / 303 stainless steel to the QQ-S-763 fastener standard, this spacer delivers corrosion resistance and dimensional stability in demanding environments. It accepts a No. 10 screw, measures 0.875 inches in overall length with an outside diameter of 0.5 inches and an inside diameter of 0.194 inches, and ships uncoated. Electricians, electronics technicians, and control board service professionals rely on this type of hardware for secure, repeatable PCB mounting.

This spacer is suited for residential and light commercial applications wherever a No. 10 screw pattern is used to mount or stack circuit boards. Common install scenarios include HVAC control board assemblies, electrical panel subassemblies, and industrial enclosure PCB mounting. The stainless steel construction makes it appropriate for environments with moisture exposure or where ferrous hardware would introduce contamination or corrosion risk.

Installation Notes

Installation is performed by qualified electricians or electronics technicians during control board assembly or replacement. Power down and de-energize all circuits before handling any PCB or mounting hardware. Use appropriate torque practices for No. 10 fasteners to avoid cracking the PCB substrate or stripping the mating screw. Follow applicable NEC guidelines when integrating PCB assemblies inside electrical enclosures.
