Electro Hardware MMF1311M06F16M3 Hex Standoff M3

Product Description

The ELECTRO HARDWARE MMF1311M06F16M3 is a male-female hex circuit board standoff designed to create precise spacing between stacked PCBs or between a circuit board and a mounting surface. Machined from aluminum alloy T3 to the QQ-A-225A Comp 2 fastener standard, this metric standoff features an M3 x 0.5 thread on both ends with a bright uncoated finish. The overall length is 14.76 mm, the hex body length is 10.00 mm, and the hex body measures 4.50 mm width across flats. It is installed by electronics technicians, PCB assembly specialists, and field service technicians working on control boards and embedded systems.

This standoff is used in PCB assemblies where a rigid, conductive or non-conductive spacer is required between board layers or between a board and an enclosure panel. Typical applications include industrial control enclosures, HVAC control boards, electrical panel subassemblies, and general electronics manufacturing. The metric M3 x 0.5 thread sizing is common across a broad range of commercial and industrial PCB mounting configurations. The male thread on one end and the female threaded bore on the other allow boards to be stacked in sequence using mating standoffs or screws.

Key Features

• M3 x 0.5 male-female thread configuration for stacked PCB mounting
• Aluminum T3 material per QQ-A-225A Comp 2 standard - lightweight and corrosion resistant
• Hex body shape allows wrench engagement for secure, torque-controlled installation
• Bright uncoated finish - no coating to chip or add dimensional variance
• Overall length of 14.76 mm with a length tolerance of -0.150 to 0.150 mm for consistent stack height
• 4.50 mm width across flats compatible with standard metric hex drivers and wrenches

Compatibility

Designed as an OEM-style metric hex standoff for PCB assemblies and control board mounting applications using M3 x 0.5 threaded fasteners.

Installation Notes

Installation is performed by electronics technicians or PCB assembly personnel using a standard metric hex wrench or nut driver sized for 4.50 mm across flats. De-energize all circuits and discharge any capacitors before handling or installing standoffs on live control boards. Avoid over-torquing aluminum standoffs, as the material is softer than steel and threads can strip under excessive force. Follow applicable IPC assembly standards for PCB hardware installation where required.
