Electro Hardware MMX1406M12-MSC Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMX1406M12-MSC is a male-male hex circuit board standoff designed to create precise spacing between printed circuit boards or between a board and a mounting surface. Threaded M3 x 0.5 on both ends, this standoff accepts screws from both sides, making it suited for stackable PCB assemblies and panel-mount configurations. The hex body profile allows for wrench tightening and consistent torque application. Constructed from Grade 2 steel with a zinc-plated finish for corrosion resistance, it meets the QQ-S-633 fastener standard. Overall length is 5.5 mm with a 5 mm width across flats.

This standoff is used in electronic assembly and PCB mounting applications across industrial controls, HVAC control boards, electrical panels, and commercial equipment enclosures. It is well suited for any application requiring metric M3 threaded standoffs to separate or secure circuit board layers. Electronics assemblers, field service technicians, and control board repair specialists are the primary installers in trade and commercial settings.

Key Features

• Male-male threaded design accepts M3 x 0.5 fasteners on both ends for stackable board assemblies
• Hex body profile enables wrench engagement for precise, repeatable installation
• Grade 2 steel construction provides reliable structural integrity in mounting applications
• Zinc-plated finish offers corrosion resistance for use in control panels and enclosures
• Meets QQ-S-633 fastener standard
• Compact 5.5 mm overall length suits tight PCB spacing requirements

Compatibility

Designed as a metric M3 x 0.5 male-male hex standoff for use in circuit board assemblies and electronic mounting applications requiring a 5.5 mm overall standoff height.

Installation Notes

Installation is typically performed by electronics assemblers or technicians servicing control boards. Always power down and de-energize equipment fully before accessing circuit boards or control assemblies. A hex wrench or nut driver sized for 5 mm width across flats is required for proper seating. Do not overtighten, as excessive force can strip the M3 threads or crack the PCB mounting hole.
