Electro Hardware MS1033M17F16D Round Board Spacer M3

Product Description

The ELECTRO HARDWARE MS1033M17F16D is a round, female unthreaded circuit board spacer designed to create a fixed standoff distance between a PCB and a mounting surface or secondary board. Made from Nylon Grade 101 material conforming to MIL-P-17091B, this spacer is built for use in electronic assemblies where a non-conductive, lightweight standoff is required. The spacer has an overall length of 0.669 inches (17 mm), an outside diameter of 0.236 inches (6 mm), and accepts an M3 screw through an inside diameter ranging from 0.126 to 0.142 inches (3.2 to 3.6 mm). The uncoated finish and nylon construction make it suitable for use where metal contact or conductivity must be avoided.

This spacer is used in residential and commercial electronic assemblies, control panels, and circuit board mounting applications. It is a common component in HVAC control board installations, industrial electronics, and equipment where PCB isolation from a chassis or secondary board is needed. The M3 thread compatibility makes it widely applicable to metric-fastener assemblies. Technicians and electronic assembly professionals install this spacer during board mounting or panel fabrication work.

Key Features

• Nylon Grade 101 construction per MIL-P-17091B for consistent, spec-controlled non-conductive performance
• Female unthreaded design accepts M3 screw for clean, tool-secured board mounting
• Overall length of 0.669 inches (17 mm) provides a fixed, reliable standoff distance
• Outside diameter of 0.236 inches (6 mm) with inside diameter range of 0.126 to 0.142 inches (3.2 to 3.6 mm)
• Uncoated, bright finish — no metallic coating that could compromise electrical isolation
• Round body shape allows consistent seating against flat PCB and panel surfaces

Compatibility

Designed as an OEM-style replacement or new-build component for electronic assemblies requiring an M3 non-conductive female unthreaded round board spacer with a 17 mm overall length.

Installation Notes

Installation is typically performed by electronics technicians or control board service professionals. Power down all equipment and discharge any capacitors before handling circuit boards or inserting spacers into an assembly. Use appropriately sized M3 fasteners and avoid overtightening, which can crack or deform nylon spacers. Follow applicable assembly documentation and any relevant IPC standards for PCB mounting procedures.
