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

Product Description

The ELECTRO HARDWARE S1079-M07-F16-H is a round, female unthreaded circuit board spacer manufactured from 18-8 and 303 grade stainless steel to meet the QQ-S-763 fastener standard. It measures 0.5 inches in overall length with a 0.375-inch outside diameter and a 0.171-inch inside diameter, sized to fit a number 8 screw. The uncoated finish leaves the base stainless steel exposed, making it suitable for environments where corrosion resistance is needed without additional plating. Electricians, electronics technicians, and control board installers use this type of spacer to maintain consistent standoff clearance between a circuit board and its mounting surface.

This spacer is used in residential and commercial applications wherever a circuit board requires a fixed standoff from a chassis, panel, or enclosure backplate. Typical installations include HVAC control boards, electrical enclosures, and industrial electronics assemblies. The female unthreaded bore accepts a number 8 fastener and allows a mating screw to pass through or seat against the spacer body. The round body shape and stainless steel construction make it a practical choice for both indoor and light-duty outdoor electrical enclosures where dimensional accuracy and corrosion resistance are priorities.

Key Features

• 18-8 and 303 grade stainless steel construction meets QQ-S-763 fastener standard
• Female unthreaded bore sized for a number 8 screw
• 0.5-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
• 0.375-inch outside diameter in a round body profile
• Uncoated finish preserves natural stainless steel corrosion resistance

Compatibility

Designed as an OEM-style and general-purpose replacement spacer for circuit board mounting applications requiring a number 8 screw, 0.5-inch standoff height, and a 0.375-inch outside diameter round body in stainless steel.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians during control board mounting or replacement. Always de-energize the equipment and verify zero voltage before working inside any electrical enclosure or panel. Use appropriately sized number 8 fasteners and verify that the spacer seats flush against the mounting surface to maintain proper board clearance. Follow applicable NEC guidelines for electrical enclosure work.
