Electro Hardware S793-M07-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S793-M07-F16-I is a round, female unthreaded circuit board spacer machined from 18-8 grade 303 stainless steel and finished uncoated. It provides a fixed standoff between a circuit board and a mounting surface, maintaining consistent clearance and preventing contact-related damage. The spacer measures 0.25 inches overall length, 0.3125 inches outside diameter, and 0.194 inches inside diameter, with a bore sized to accept a number 10 screw. It meets the QQ-S-763 federal fastener standard. Electricians, electronics technicians, and controls-panel assemblers install this type of hardware during board mounting in control enclosures and equipment panels.

This spacer is suited for use in control panels, electrical enclosures, and electronic assemblies where a number 10 fastener is used to mount a printed circuit board. Its compact 0.25-inch length makes it appropriate for tight board-to-chassis clearances in residential and light commercial control systems. The 18-8 stainless steel construction resists corrosion in environments where moisture or mild chemical exposure is a concern, making it a reliable choice for HVAC control boards, pool equipment panels, and similar trade applications.

Key Features

• Female unthreaded bore accepts a number 10 screw for secure, tool-assisted board mounting
• 18-8 grade 303 stainless steel construction resists corrosion without a separate finish coating
• Meets QQ-S-763 federal specification for stainless steel fastener stock
• Precise 0.25-inch length with a length tolerance of -0.005 to 0.005 inches for consistent standoff height
• Inside diameter tolerance of 0.000 to 0.010 inches ensures reliable screw fit
• Round body shape for standard board-mounting footprint

Compatibility

Designed as an OEM-style replacement or stock hardware component for circuit board mounting applications requiring a number 10 screw, a 0.25-inch standoff height, and a 5/16-inch outside diameter round spacer in stainless steel.

Installation Notes

Installation is typically performed by a licensed electrician or qualified controls technician. Always de-energize the panel and follow lockout/tagout procedures before accessing any control board or enclosure. Use the appropriate number 10 screw and driver; do not overtighten, as this can crack the board or distort the spacer. Installations in electrical enclosures should conform to applicable NEC requirements for panel wiring and component clearances.
