Electro Hardware MMF1323M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1323M06F16M3 is an aluminum male-female hex circuit board standoff designed to create fixed spacing between PCBs or between a board and a chassis panel. The standoff features M3x0.5 threading on both the male and female ends, a hexagonal body measuring 4.5 mm across flats, and an overall length of 20.76 mm. It is manufactured from 2024-T3 aluminum in a bright, uncoated finish and meets QQ-A-225A Comp 2 material standards. Electronics assembly technicians and PCB integration specialists install these fasteners during board mounting and enclosure builds.

This standoff is suited for metric-threaded PCB mounting applications in electronics assemblies, control panels, and enclosures where reliable board-to-board or board-to-chassis spacing is required. The hex body shape allows installation and removal with standard hex drivers or wrenches. Typical applications include industrial control boards, signal processing assemblies, and any application requiring a rigid, non-shifting standoff in a metric fastener system.

Key Features

• Male-female configuration allows stacking or panel attachment in a single fastener
• M3x0.5 thread on both ends for compatibility with standard metric hardware
• Hex body at 4.5 mm across flats for tool-driven installation and torque control
• Bright, uncoated aluminum finish - no coating to flake or contaminate sensitive electronics
• Meets QQ-A-225A Comp 2 material standard for aluminum alloy specification compliance
• Tight length tolerance of -0.150 mm to 0.150 mm ensures consistent board spacing

Compatibility

Designed for use in metric M3x0.5 threaded PCB mounting applications. Suitable for any assembly requiring an aluminum hex standoff with a 20.76 mm overall length and 16.00 mm body length in a metric fastener system.

Installation Notes

Installation is typically performed by electronics assembly technicians or PCB integration specialists using a hex driver or open-end wrench sized for 4.5 mm across flats. Power down and discharge all capacitors in the assembly before handling circuit boards or installing standoffs. Do not overtighten - thread engagement should be firm and snug without deforming the aluminum threads. Follow applicable IPC assembly standards for board mounting hardware where required.
