Electro Hardware MMF1307M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1307M06F16M3 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, mounting plates, and enclosure panels. Machined from aluminum alloy to the QQ-A-225A Comp 2 standard, this standoff features an M3x0.5 thread on both the male pin and female threaded bore. The overall length is 12.76 mm (approximately 0.502 inches), with a hexagonal body measuring 4.50 mm (approximately 0.177 inches) across flats for positive wrench engagement. The bright, uncoated finish keeps the aluminum bare for applications where coating buildup or additional plating is not acceptable. Electronics assemblers, PCB technicians, and enclosure integrators install this type of hardware during board-level assembly and chassis builds.

This standoff is suited for metric-threaded circuit board stacking and panel mounting applications in commercial and industrial electronics assemblies. The male-female configuration allows boards to be stacked in series or secured to a base panel while leaving a female thread exposed for the next fastener. The 8.00 mm hex body length and 4.76 mm thread length on the male end make it appropriate for close-tolerance PCB stackup work where consistent standoff height and thread engagement are critical.

Key Features

• Male-female hex configuration for stackable PCB and panel mounting
• M3x0.5 thread on both male pin and female bore for metric fastener compatibility
• Hexagonal body with 4.50 mm width across flats for wrench or driver engagement
• Aluminum construction to QQ-A-225A Comp 2 standard, Material Grade T3
• Bright, uncoated finish suitable for applications requiring bare aluminum
• Length tolerance of -0.150 mm to +0.150 mm for consistent stackup height

Compatibility

Designed as a standard metric hex standoff for PCB stacking and enclosure panel mounting applications using M3x0.5 threaded fasteners.

Installation Notes

Installation is performed by electronics assemblers and PCB technicians using an appropriate hex driver or wrench sized for 4.50 mm across flats. Torque the standoff only to the level needed for firm seating without deforming the aluminum threads. Ensure mating board holes are correctly sized and deburred before driving the male pin through. Do not use power tools at high speed, as aluminum threads can strip easily under excessive torque.
