Electro Hardware MS1001M07F16F Circuit Board Spacer M4

Product Description

The ELECTRO HARDWARE MS1001M07F16F is a round, female unthreaded circuit board spacer designed for M4 screw applications in PCB mounting assemblies. Manufactured from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer delivers corrosion resistance and dimensional stability in demanding environments. It measures 1 mm overall length with a 6 mm outside diameter and an inside diameter ranging from 4.2 to 4.8 mm. The uncoated bright finish is suitable for applications where a bare metal surface is required. Electronics assembly technicians and field service professionals working on control boards, HVAC units, and industrial enclosures rely on this type of hardware for precise board standoff and secure mounting.

This spacer is appropriate for use in residential and commercial electronics assemblies, control panel builds, and PCB mounting applications where an M4 fastener is specified. Its compact 1 mm length makes it suited for tight board-to-board or board-to-chassis clearances. The metric form factor aligns with OEM-style control board replacements and new-build assemblies across HVAC, electrical, and industrial equipment platforms. Minimum order quantity is 10 units; each package contains 1 piece.

Key Features

• Grade 303 stainless steel construction per QQ-S-763 fastener standard
• M4 screw size, female unthreaded body for PCB mounting applications
• 1 mm overall length with length tolerance of -0.13 to 0.13 mm
• 6 mm outside diameter; inside diameter 4.2 to 4.8 mm with 0 to 0.27 mm tolerance
• Bright uncoated finish — no coating to interfere with grounding or bare-metal contact requirements
• Round body shape for consistent seating on standard PCB mounting pads

Compatibility

Designed as an OEM-style metric circuit board spacer for M4 screw applications in PCB and control board assemblies across electronics, HVAC controls, and industrial enclosure platforms.

Installation Notes

Installation is performed by electronics assembly technicians or licensed trades when servicing or building control boards in HVAC, electrical, or industrial equipment. Power down and de-energize all equipment before handling circuit board hardware. Use appropriate ESD precautions when working near populated PCBs. Verify M4 fastener engagement and board clearance requirements before finalizing spacer selection.
