Electro Hardware MMF1801M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1801M06F16M4 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic enclosures and control assemblies. Machined from T3-grade aluminum with a bright, uncoated finish, it meets QQ-A-225A Comp 2 material standards. The standoff features an M4x0.7 thread on both the male and female ends, an overall length of 14.53 mm, and a 6 mm hex body for wrench engagement. It is commonly installed by electronics technicians, panel builders, and HVAC control board assemblers working with metric fastener systems.

This standoff is suited for use in residential and commercial control panels, PCB stacking applications, and equipment enclosures where metric hardware is required. The hex body shape allows precise torque application during assembly. The aluminum construction keeps weight low while providing adequate mechanical strength for board-mounting applications in light-duty industrial and HVAC electronic assemblies.

Key Features

• M4x0.7 thread on both male and female ends for secure, stackable PCB mounting
• Hex body shape at 6 mm width across flats for standard wrench or nut-driver installation
• T3-grade aluminum construction - lightweight and corrosion-resistant in controlled environments
• Bright uncoated finish; meets QQ-A-225A Comp 2 material standard
• Overall length of 14.53 mm with a length tolerance of -0.150 to 0.150 mm for consistent stack height
• Metric system of measurement - compatible with M4-threaded PCB mounting schemes

Compatibility

Designed as an OEM-style replacement or new-installation standoff for metric PCB assemblies requiring M4x0.7 threaded hardware with a 6 mm hex body profile.

Installation Notes

Installation is performed by electronics technicians or panel builders using a standard 6 mm nut driver or open-end wrench. Power down and de-energize all circuits before working inside any control enclosure or panel. Avoid overtightening, as the aluminum threads can be damaged by excessive torque. Verify thread engagement depth matches the mating board thickness before final assembly.
