Electro Hardware S797-M07-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S797-M07-F16-I is a round, female unthreaded circuit board spacer machined from 18-8 grade 303 stainless steel and supplied uncoated. It is designed to create a fixed standoff gap between a printed circuit board and a mounting surface, keeping the board secure and electrically isolated from chassis contact. The spacer measures 5/16 inches overall length (0.3125 inches), with an outside diameter of 5/16 inches (0.3125 inches) and an inside diameter of 0.194 inches. It accepts a number 10 screw. Licensed electricians and electronics technicians install these spacers during control board mounting in HVAC, industrial, and electrical enclosure applications.

This spacer is suited for use in any application requiring a compact, corrosion-resistant standoff for printed circuit board assemblies. Typical installations include residential and commercial HVAC control board mounting, electrical panel assemblies, and industrial equipment enclosures where stainless steel construction is preferred for durability and corrosion resistance. The female unthreaded design accepts a number 10 fastener passed through the board and spacer for secure panel attachment. Its small profile and precise tolerances make it appropriate for tight board layouts.

Key Features

• 18-8 grade 303 stainless steel construction for corrosion resistance in demanding environments
• Female unthreaded body accepts number 10 screws
• 5/16 inch overall length provides consistent standoff height for circuit board clearance
• Inside diameter tolerance of 0.000 to 0.010 inches ensures repeatable fit
• Length tolerance held to -0.005 to 0.005 inches for precise stack-up control
• Uncoated finish - no risk of coating thickness affecting dimensional fit

Compatibility

Designed as a standard OEM-style round circuit board spacer for use with number 10 screw fasteners in PCB mounting applications across HVAC, electrical, and industrial enclosure assemblies.

Installation Notes

Install by a qualified electrician or electronics technician. De-energize all equipment and follow applicable NEC requirements before servicing any control board or electrical enclosure. Position the spacer between the circuit board and the mounting surface before passing the number 10 fastener through. Do not overtighten fasteners through unthreaded spacers, as this can crack the board or deform the spacer.
