Product Description

The ELECTRO HARDWARE S297M07F16E is a round, female unthreaded circuit board spacer designed to create precise standoff clearance between a PCB and a mounting surface. Machined from Grade 303 stainless steel and left uncoated with a bright finish, this spacer meets fastener standard QQ-S-763. It accepts a No. 4 screw, measures 0.3125 inches overall length, and carries an inside diameter of 0.116 inches with an outside diameter of 0.1875 inches. Electricians, control board technicians, and electronics assembly pros use this spacer wherever corrosion resistance and dimensional consistency are required.

This spacer is suited for light commercial and residential control panel assemblies, HVAC circuit board mounting, and general electronics enclosure work. Its compact round body and stainless construction make it a reliable choice in environments where moisture or mild chemical exposure is a concern. It is sold individually and is appropriate for both new assembly and field replacement of worn or damaged spacers on control boards.
