Electro Hardware MMX1402M06MSC-1 Hex Standoff M4

Product Description

The ELECTRO HARDWARE MMX1402M06MSC-1 is a male-male hex circuit board standoff designed for metric fastening applications in electronic assemblies and PCB mounting configurations. Machined from aluminum alloy to Grade T-3 specification and finished with a clear coating, this standoff meets QQ-A-225A Comp 2 standards. The overall length is 3.5 mm, with a 5 mm hex body width across flats and available thread lengths of 8.5 mm, 9 mm, or 9.5 mm on the M4 x 0.7 male threads at both ends. Electronics technicians, automation integrators, and board-level assembly professionals use this type of hardware to space and secure PCBs within enclosures and chassis.

This standoff is suited for residential and commercial electronic control board assemblies, industrial automation panels, HVAC control enclosures, and similar applications where metric M4 x 0.7 threaded hardware is required. The hex body shape allows for tool-driven installation in tight PCB layouts. Its compact 3.5 mm body length makes it appropriate for close-clearance board stacking or chassis-mount scenarios where minimal height offset is needed.

Key Features

• Male-male hex configuration for PCB-to-chassis or board-to-board spacing
• M4 x 0.7 thread size on both ends for standard metric fastening
• 3.5 mm overall body length for minimal-clearance installations
• 5 mm width across flats allows wrench or nut-driver installation
• Aluminum construction, Grade T-3, with clear finish for corrosion resistance
• Meets QQ-A-225A Comp 2 fastener standard

Compatibility

Designed as a standard metric M4 x 0.7 male-male hex standoff for use in PCB mounting, electronic enclosures, and control board assemblies requiring aluminum hex standoffs to QQ-A-225A Comp 2 specification.

Installation Notes

Installation is typically performed by electronics technicians or control system integrators. De-energize all boards and enclosures before installing or removing standoffs. Use an appropriate metric hex wrench or nut driver sized for 5 mm across flats to avoid deforming the hex body. Length tolerance for this standoff is -0.15 mm to 0.15 mm; verify clearance requirements before installing in precision stacking applications.
