Electro Hardware MMX1406M12MSC-1 Hex Standoff M4

Product Description

The ELECTRO HARDWARE MMX1406M12MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, panels, and chassis components in electronic assemblies. The standoff features an M4 x 0.7 thread on both ends, a 5.5 mm overall length, and a hex body with 5 mm width across flats for wrench engagement. Constructed from Grade 2 steel with a zinc-plated finish, it meets the QQ-S-633 standard for corrosion resistance. Thread length ranges across 8.5 mm, 9 mm, and 9.5 mm configurations. This hardware is used by electronics assemblers, panel builders, and field technicians working on control boards, enclosures, and rack-mounted equipment.

This standoff is suited for metric PCB mounting applications in HVAC control panels, electrical enclosures, and industrial equipment. It provides a secure, conductive metal standoff point between two male-threaded mounting surfaces. The hex body profile allows installation and removal with a standard hex wrench or nut driver, making it practical in tight panel layouts. Its compact 5.5 mm overall length fits low-profile board stacking configurations commonly found in residential and commercial control equipment.

• Hex body with 5 mm width across flats for wrench-driven installation
• Grade 2 steel construction with zinc-plated finish per QQ-S-633
• Thread lengths available: 8.5 mm, 9 mm, and 9.5 mm
• Single-piece metric hardware; sold individually

Compatibility

Designed as an OEM-style metric standoff for PCB and panel mounting applications requiring M4 x 0.7 male-male thread engagement in steel hardware configurations.

Installation Notes

Installation is performed by electronics assemblers, panel builders, or service technicians working on control boards and electrical enclosures. Always power down and de-energize the equipment before handling circuit boards or fasteners in a live panel. A hex wrench or nut driver sized to 5 mm across flats should be used to seat the standoff without overtightening, which can strip the metric threads or crack a PCB mounting hole. Follow applicable assembly standards and torque guidelines specified by the equipment manufacturer.
