Electro Hardware S797-M07-F16-H Circuit Board Spacer No. 8

Product Description

The ELECTRO HARDWARE S797-M07-F16-H is a round, female unthreaded circuit board spacer designed to create precise standoff clearance between a PCB and a mounting surface or adjacent board. Machined from 18-8 / 303 stainless steel with a bright uncoated finish, it accepts a No. 8 screw and provides a 0.3125-inch overall length. The 0.171-inch inside diameter and 0.3125-inch outside diameter deliver a compact, consistent standoff in tight board layouts. This spacer meets fastener standard QQ-S-763. Electronics technicians, field service engineers, and panel builders install this type of hardware during board mounting and enclosure assembly work.

This spacer is suited for residential and commercial electronics assemblies, control panels, and circuit board mounting applications where stainless steel corrosion resistance and dimensional consistency are required. It is commonly used in HVAC control boards, electrical enclosure assemblies, and industrial panel builds where a No. 8 fastener pattern is specified and a female unthreaded standoff is needed to maintain board-to-surface clearance.

Key Features

• 18-8 / 303 stainless steel construction meets fastener standard QQ-S-763
• Female unthreaded design accepts No. 8 screws for straightforward board mounting
• 0.3125-inch overall length with a tight length tolerance of -0.005 to +0.005 inches
• 0.171-inch inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches
• Bright uncoated finish - no coating to add dimensional variation or interfere with grounding
• Round body shape with 0.3125-inch outside diameter fits standard PCB standoff footprints

Compatibility

Designed as an OEM-style replacement or direct-fit standoff spacer for circuit board assemblies requiring a No. 8 screw, female unthreaded, round stainless steel spacer with a 0.3125-inch overall length and 0.3125-inch outside diameter.

Installation Notes

De-energize and lock out all power to the control panel or circuit board assembly before installing or replacing board spacers. This spacer is installed by electronics technicians and qualified electricians working under applicable NEC guidelines for panel and enclosure work. Use appropriate non-marring hand tools to seat the spacer without distorting the board or mounting surface. Do not overtighten the mating No. 8 fastener, as stainless steel hardware is susceptible to galling if torque is applied too rapidly.
