Electro Hardware S1059-M04-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1059-M04-F16-I is a round, female unthreaded circuit board spacer machined from aluminum grade T-3 to QQ-A-225A Comp 2 specification. It measures 0.1875 inches overall length with an inside diameter of 0.194 inches and an outside diameter of 0.375 inches. Sized for a number 10 screw, this spacer is used to maintain precise standoff distance between a printed circuit board and a mounting surface or between stacked boards. Electronics assemblers, field service technicians, and panel wiring professionals install this type of hardware during board mounting and enclosure assembly operations.

This spacer is suited for residential and commercial electronic control panel assemblies, HVAC control boards, and general printed circuit board mounting applications where a lightweight, corrosion-resistant aluminum standoff is required. The uncoated finish is appropriate for indoor enclosure environments. The female unthreaded bore accepts a number 10 fastener and allows the installer to determine thread engagement method. It is sold individually with a minimum order quantity of 5 units.

Compatibility

Designed as a standard number 10 screw circuit board spacer for use in electronic control assemblies, printed circuit board mounting configurations, and enclosure panel builds where a 0.1875-inch aluminum standoff is specified.

Installation Notes

Installation is performed by electronics assembly technicians or field service personnel working on control panels and circuit board assemblies. Power down and de-energize all circuits before handling or replacing board mounting hardware. Use appropriately sized number 10 fasteners and avoid over-torquing, which can crack board substrate or deform the spacer bore. Verify standoff height requirements against board clearance specifications before installation.
