Electro Hardware MMX1406M06MSC-1 Hex Standoff M4

Product Description

The ELECTRO HARDWARE MMX1406M06MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, mounting plates, and enclosure panels. Machined from aluminum to Grade T-3 with a clear finish, this standoff has an overall length of 5.5 mm, a hex body width across flats of 5 mm, and an M4 x 0.7 thread on both ends. Thread length ranges from 8.5 mm to 9.5 mm. Electronics assembly technicians, field service techs, and panel builders use these standoffs when stacking or securing circuit boards in HVAC control panels, electrical enclosures, and similar low-voltage assemblies.

This standoff is suited for applications requiring a compact, lightweight fastener in tight board layouts. The metric M4 x 0.7 thread pitch is common in light industrial and commercial control board assemblies. The aluminum construction keeps weight minimal and resists corrosion in indoor enclosure environments. The hex body profile allows installation and removal with a standard wrench or hex driver, making it practical for benchtop assembly and field service alike.

Key Features

• Thread length options of 8.5 mm, 9 mm, and 9.5 mm

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board assemblies requiring M4 x 0.7 metric male-male hex standoffs with a 5.5 mm overall body length.

Installation Notes

Installation is performed by electronics assembly technicians or field service professionals. De-energize all control boards and panels before installing or removing standoffs to prevent damage to sensitive components. Use an appropriately sized wrench or hex driver matched to the 5 mm width across flats to avoid rounding the hex body. Verify thread engagement on both mating ends before applying torque to ensure proper seating.
