Electro Hardware S293M07F16E Round Board Spacer 4

Product Description

The ELECTRO HARDWARE S293M07F16E is a round, female unthreaded circuit board spacer designed to provide precise standoff spacing between a PCB and a mounting surface. Built from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer delivers corrosion resistance and dimensional consistency in demanding environments. It accepts a Number 4 screw, measures 0.25 inches overall length, 0.1875 inches outside diameter, and 0.116 inches inside diameter. The bright, uncoated finish leaves the material in its natural state without added plating. Licensed electricians and electronics technicians install this type of component during panel assembly, control board mounting, and enclosure builds.

This spacer is suited for residential and light commercial electrical and HVAC control board assemblies where compact standoff hardware is required. Its small outside diameter of 0.1875 inches makes it appropriate for tight PCB layouts with close component spacing. The stainless steel construction suits indoor and mildly corrosive environments. It is sold individually and is a direct fit wherever a Number 4, female unthreaded, round circuit board spacer with 0.25-inch length is specified.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians during control board assembly or panel mounting. Power down and de-energize the circuit completely before handling or positioning circuit boards. Use appropriate Number 4 fasteners matched to the mating board or enclosure tapped hole. Follow applicable NEC guidelines for enclosure and control board assembly practices.
