Electro Hardware MMX1445M06MSC-1 Hex Standoff M4

Product Description

The ELECTRO HARDWARE MMX1445M06MSC-1 is a male-male hex circuit board standoff used to separate and support printed circuit boards within electronic assemblies. This metric fastener features an M4 x 0.7 thread on both ends, a 25 mm overall length, and a 5 mm hex body width across flats. Machined from Grade T-3 aluminum with a clear finish, it meets the QQ-A-225A Comp 2 fastener standard. Electronics assemblers, electrical technicians, and field service technicians install these standoffs when mounting or stacking PCBs in control panels, enclosures, and equipment chassis.

This standoff is suited for metric PCB mounting applications in commercial and industrial electronic assemblies, control boards, and enclosure builds. The male-male configuration allows boards to be spaced and secured with a mating nut or threaded receiver on each end. Thread length ranges from 8.5 mm to 9.5 mm, providing engagement flexibility across different board thicknesses and mounting configurations. Typical use cases include control panel wiring assemblies and electronic equipment chassis builds requiring a lightweight, corrosion-resistant spacer.

Key Features

• Male-male hex configuration for dual-end threaded PCB mounting
• M4 x 0.7 metric thread on both ends for secure board engagement
• 25 mm overall length with hex body for wrench-assisted installation
• Grade T-3 aluminum construction for lightweight, corrosion-resistant service
• Clear finish meets QQ-A-225A Comp 2 fastener standard
• Length tolerance of -0.150 mm to 0.150 mm for precision fitment

Compatibility

Designed for metric PCB standoff applications requiring an M4 x 0.7 male-male hex fastener in aluminum construction. Suitable for use in electronic enclosures and control assemblies where a 25 mm spacing height and 5 mm hex body are required.

Installation Notes

Install and remove using a 5 mm hex wrench or open-end wrench matched to the body width across flats. Always de-energize and discharge any circuit board assembly before handling or installing standoffs. Do not overtighten, as aluminum threads can be damaged by excessive torque. Follow applicable electrical codes and equipment manufacturer guidelines when working inside control panels or energized enclosures.
