Electro Hardware MMF1807M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1807M06F16M4 is an aluminum male-female hex circuit board standoff designed to space and fasten printed circuit boards within electronic enclosures, control panels, and HVAC equipment assemblies. The standoff features an M4 x 0.7 thread on both the male and female ends, with an overall length of 17.53 mm (approximately 0.69 inches) and a hexagonal body that measures 6 mm (approximately 0.24 inches) across the flats. The body length is 8.00 mm and the thread depth is 11.10 mm, providing a secure engagement for standard M4 fasteners. Manufactured from T3-grade aluminum to the QQ-A-225A Comp 2 specification, this standoff delivers a lightweight, corrosion-resistant solution for PCB mounting tasks.

This standoff is suited for use in residential and commercial electronics and electromechanical assemblies where PCBs must be elevated and secured at a fixed distance from a mounting surface or a second board. Common install scenarios include control board assemblies in HVAC equipment, motor control panels, and field service replacements of damaged or corroded standoffs. The metric M4 thread size and 6 mm hex body make it compatible with standard metric tooling. This part ships in a single-piece package and is ordered in multiples of 10.

Key Features

• Male-female configuration accepts M4 x 0.7 fasteners on both ends for stacked PCB assemblies
• Hexagonal body (6 mm across flats) allows positive wrench engagement during installation
• T3-grade aluminum construction per QQ-A-225A Comp 2 specification
• Bright uncoated finish maintains bare aluminum contact surface
• Length tolerance held to -0.150 to 0.150 mm for precise board spacing
• Lightweight design minimizes added load on PCB mounting points

Compatibility

Designed as a standard metric M4 x 0.7 male-female hex standoff suitable for circuit board mounting applications requiring a 6 mm hex body profile and aluminum construction.

Installation Notes

Installation is typically performed by electronics technicians or electricians during control board assembly or field repair. Power down and de-energize the equipment completely before handling circuit boards or replacing standoffs. Use a 6 mm hex wrench or nut driver to seat the standoff without overtightening, which can crack PCB mounting holes. Follow applicable NEC requirements and equipment manufacturer guidelines when working inside energized enclosures.
