Electro Hardware S285M07F16E Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S285M07F16E is a round, female unthreaded circuit board spacer designed for use with number 4 screw fasteners. Machined from Grade 303 stainless steel and left uncoated with a bright finish, this spacer meets fastener standard QQ-S-763. It measures 0.125 inches overall length, 0.1875 inches outside diameter, and 0.116 inches inside diameter, making it a precision fit for tight PCB mounting applications. Licensed electricians and electronics assembly technicians working in HVAC controls, electrical panels, or industrial PCB assemblies rely on hardware like this to maintain consistent board standoff heights and secure, vibration-resistant mounting.

This spacer is suited for residential and commercial circuit board assemblies where a compact, corrosion-resistant standoff is required. Its stainless steel construction makes it appropriate for environments with moisture exposure or where ferrous hardware is unacceptable. Typical applications include control board mounting in HVAC equipment, electrical enclosures, and similar light-assembly electronic installations where a number 4 screw pattern is used.

Key Features

• Grade 303 stainless steel construction meets QQ-S-763 fastener standard
• Female unthreaded design sized for number 4 screws
• Compact 0.125 inch overall length for low-profile board standoff applications
• Bright uncoated finish maintains dimensional accuracy without added coating thickness
• Inside diameter tolerance of 0.000 to 0.010 inches and length tolerance of -0.005 to 0.005 inches for precise fitment
• Round body shape for uniform seating against circuit board surfaces

Compatibility

Designed as an OEM-style replacement or service spacer for circuit board assemblies using number 4 screw fasteners requiring a 0.125 inch female unthreaded round standoff in the inch measurement system.

Installation Notes

Installation is typically performed by licensed electricians or qualified electronics assembly technicians. Power down and de-energize all equipment before servicing any circuit board or control assembly. Use appropriate ESD precautions when handling PCBs. Follow applicable NEC guidelines and equipment manufacturer procedures when replacing or installing circuit board hardware.
