Electro Hardware MMF1829M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1829M06F16M4 is a male-female hex circuit board standoff designed to create precise, fixed spacing between PCBs and mounting surfaces or between stacked boards. Machined from aluminum alloy to QQ-A-225A Comp 2 standards, it features a bright uncoated finish and a hexagonal body that accepts a wrench for controlled installation. The M4x0.7 male thread on one end and M4x0.7 female threaded bore on the other allow boards to be secured and stacked in sequence. With an overall length of 28.53 mm and a body length of 19.00 mm, this standoff suits compact PCB assemblies where consistent standoff height is critical.

This standoff is used in electronics enclosures, industrial control panels, HVAC control boards, and other assemblies where printed circuit boards must be mechanically isolated and stacked at a defined distance. The metric M4x0.7 thread sizing is common in OEM equipment manufacturing, panel-build environments, and field-replacement scenarios. Electricians and electronics technicians install these during control board replacement or new-build panel assembly work. The hex body allows installation with standard 6 mm hex wrenches or nut drivers, keeping the installation process straightforward in tight enclosures.

Key Features

• Male-female hex configuration allows secure PCB stacking and sequential board mounting
• M4x0.7 thread on both ends for compatibility with standard metric fastener hardware
• 6 mm width across flats accepts standard hex wrenches and nut drivers for precise torque control
• Aluminum construction meets QQ-A-225A Comp 2 specification, Material Grade T3
• Bright uncoated finish with a length tolerance of -0.150 to 0.150 mm for consistent stacking height
• Overall length of 28.53 mm with a thread depth of 11.10 mm for secure fastener engagement

Compatibility

Designed as an OEM-style metric standoff for use in PCB assemblies, electronic enclosures, and control panel builds requiring M4x0.7 male-female hex standoffs with a 6 mm hex body.

Installation Notes

Installation is performed by electricians, electronics technicians, or panel builders during control board assembly or replacement. Power down and de-energize all equipment before working inside enclosures. Use a 6 mm hex wrench or nut driver to seat the standoff firmly without overtightening, which can strip the aluminum threads. Follow applicable NEC or equipment manufacturer guidelines for panel assembly and component mounting.
