Electro Hardware S1079-M07-F16-I Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1079-M07-F16-I is a round, female unthreaded circuit board spacer designed to maintain precise standoff distance between a PCB and its mounting surface. Machined from 18-8 Grade 303 stainless steel and left uncoated, it meets fastener standard QQ-S-763. The spacer measures 0.5 inches overall length, with a 0.375-inch outside diameter and a 0.194-inch inside diameter sized for a 10 screw. Length tolerance is held to plus or minus 0.005 inches, and inside diameter tolerance runs 0.000 to 0.010 inches, making it suitable for precision board mounting applications.

This spacer is used in electronic control board assemblies found in HVAC equipment, electrical panels, pool equipment controllers, and similar trade-installed systems where circuit boards require secure, corrosion-resistant standoff support. The stainless steel construction makes it appropriate for installations in humid or corrosive environments. It is installed by HVAC technicians, electricians, and control board service professionals during board replacement or panel fabrication work.

Key Features

• 18-8 Grade 303 stainless steel construction for corrosion resistance
• Meets QQ-S-763 fastener standard
• Female unthreaded bore sized for 10 screw fasteners
• Tight length tolerance of plus or minus 0.005 inches for consistent board standoff height
• Inside diameter tolerance of 0.000 to 0.010 inches for secure screw fitment
• Uncoated finish — no coating to chip or degrade in service

Compatibility

Designed as a standard 10 screw round circuit board spacer for use in PCB mounting applications requiring a 0.5-inch standoff with a 0.375-inch outside diameter female unthreaded body.

Installation Notes

Installation is performed by qualified electricians or electronics-trained HVAC technicians. De-energize all power to the control board assembly before servicing any PCB mounting hardware. Use appropriately sized 10 fasteners to avoid distorting the unthreaded bore. Follow applicable NEC guidelines and equipment manufacturer torque recommendations for board mounting hardware.
