Electro Hardware S1055-M07-F16-J Circuit Board Spacer 12

Product Description

The ELECTRO HARDWARE S1055-M07-F16-J is a round, female unthreaded circuit board spacer designed to maintain precise separation between PCBs and mounting surfaces in electronic assemblies. Machined from 18-8 and 303 grade stainless steel and left uncoated, it meets fastener standard QQ-S-763. The spacer measures 0.125 inches overall length, 0.375 inches outside diameter, and 0.219 inches inside diameter, accepting a number 12 screw. Its close-tolerance construction ensures consistent stack height and reliable board support in demanding environments where corrosion resistance matters.

This spacer is suited for use in control board assemblies, industrial enclosures, HVAC control panels, and similar electronic mounting applications where a stainless steel standoff is required. The female unthreaded design allows a number 12 fastener to pass through freely, making it appropriate for use as a through-mount spacer in both single-board and multi-board configurations. Electricians, control panel builders, and electronics technicians handling circuit board replacement or new-build panel work will find this spacer compatible with standard PCB mounting layouts.

Installation Notes

Installation is performed by electricians or electronics technicians during control board assembly or replacement. Power down the equipment completely and discharge any capacitors before handling circuit boards or replacing standoffs. Use appropriately sized number 12 fasteners and avoid over-torquing, which can crack board material or deform the spacer. Follow applicable NEC guidelines and equipment manufacturer instructions when working inside electrical enclosures.
