Electro Hardware MS1003M17F16D Round Circuit Board Spacer M3

Product Description

The ELECTRO HARDWARE MS1003M17F16D is a round, female unthreaded circuit board spacer designed to maintain consistent standoff clearance between a PCB and a mounting surface. Molded from Nylon Grade 101 and left uncoated, this spacer meets MIL-P-17091B fastener standards. It accepts an M3 screw, measures 2 mm in overall length, and has an outside diameter of 6 mm with an inside diameter range of 3.2 to 3.6 mm. Electronics assemblers, PCB technicians, and panel wiring professionals install this type of hardware during board mounting and chassis assembly work where consistent spacing and electrical isolation are required.

This spacer is suited for use in low-voltage electronics assemblies, control panel builds, and printed circuit board mounting applications where an M3 metric fastener is the specified screw size. The nylon construction provides electrical insulation and corrosion resistance, making it appropriate for both commercial and industrial PCB installations. Its compact 2 mm overall length makes it a practical choice for tight board-to-chassis clearances in embedded control systems, HVAC control boards, and similar electronic sub-assemblies.

Key Features

• Female unthreaded body accepts M3 metric screws for tool-free alignment during board placement
• Nylon Grade 101 material provides electrical insulation and lightweight corrosion resistance
• Meets MIL-P-17091B fastener standard for consistent dimensional quality
• 2 mm overall length suits tight PCB-to-panel standoff requirements
• 6 mm outside diameter with 3.2 to 3.6 mm inside diameter for snug M3 fitment
• Uncoated bright finish — no outgassing or coating interference with PCB components

Compatibility

Designed as an OEM-style replacement or service spacer for PCB mounting applications requiring an M3 metric screw size with a round, female unthreaded nylon standoff body.

Installation Notes

Installation is performed by electronics technicians and panel wiring professionals. Power down and de-energize all circuits before handling or replacing PCB hardware. Use appropriate M3 fastener torque practices per board or chassis manufacturer guidelines to avoid cracking the nylon body. Handle nylon spacers carefully in high-heat environments, as sustained elevated temperatures can affect dimensional stability.
