Electro Hardware S1339-M07-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1339-M07-F16-H is a round, female unthreaded circuit board spacer machined from 18-8 grade 303 stainless steel to meet fastener standard QQ-S-763. It measures 0.1875 inches overall length, with a 0.5000 inch outside diameter and a 0.171 inch inside diameter sized for a number 8 screw. The uncoated finish leaves the stainless steel bare for corrosion resistance without added plating. Electronics technicians, field service engineers, and trade professionals use this spacer to maintain precise board-to-chassis standoff distances in control panel and circuit board assemblies.

This spacer is suited for residential and commercial control board assemblies, HVAC control panels, electrical enclosures, and any application requiring a precise standoff between a printed circuit board and a mounting surface. Its female unthreaded body accepts a number 8 fastener and provides consistent height control across the board mounting plane. The round body shape and stainless steel construction make it appropriate for environments where light moisture exposure or vibration is a concern.

Key Features

Compatibility

Designed as a standard OEM-style round circuit board spacer for use with number 8 fasteners in inch-measurement circuit board and control panel mounting applications.

Installation Notes

Installation is performed by electronics technicians or qualified trade professionals working on control board assemblies. De-energize and lock out the equipment before accessing any control board or panel. Verify the mating fastener is a number 8 screw with appropriate thread engagement for the application. Do not overtighten fasteners through unthreaded spacers, as the bore does not provide thread resistance.
