Electro Hardware S1383-M07-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1383-M07-F16-H is a round, female unthreaded circuit board spacer designed to create a fixed standoff gap between a printed circuit board and a mounting surface. Machined from 18-8 Grade 303 stainless steel and left uncoated, this spacer meets the QQ-S-763 fastener standard. It accepts a number 8 screw, measures 0.875 inches overall length, 0.5 inches outside diameter, and 0.171 inches inside diameter. Its corrosion-resistant construction makes it suitable for electronics assemblies exposed to moisture or temperature variation. Electricians, HVAC technicians, and electronics assembly pros reach for this type of hardware when mounting control boards, relay panels, or PCB assemblies where precise board standoff height is required.

This spacer is used in residential and commercial applications wherever a circuit board requires mechanical separation from a chassis, enclosure, or secondary board. Typical install scenarios include HVAC control board mounting, electrical enclosure PCB installations, and industrial electronics assemblies. The unthreaded female body accepts a standard number 8 fastener passed through from the board side, with a mating screw securing from the chassis side. Its small outside diameter and tight length tolerance make it well suited for high-density board layouts where clearance between components is limited.

Key Features

• 18-8 Grade 303 stainless steel construction resists corrosion without a finish coating
• Meets QQ-S-763 fastener standard for stainless steel hardware
• Female unthreaded body accepts a number 8 screw
• Overall length of 0.875 inches with a tight length tolerance of -0.005 to 0.005 inches
• Inside diameter tolerance of 0.000 to 0.010 inches ensures consistent fitment on number 8 fasteners
• Round body shape with 0.5 inches outside diameter suits standard PCB mounting hole patterns

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications requiring a number 8 screw, female unthreaded round standoff in inch measurements.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians. Always power down and de-energize the equipment before handling or replacing any circuit board hardware. Use properly rated number 8 fasteners and do not overtighten, as stainless fasteners can gall if driven without appropriate lubrication or care. Follow applicable NEC guidelines when working inside electrical enclosures.
