Electro Hardware MMX1402M09-MSC Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMX1402M09-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, mounting panels, and enclosure surfaces in electronic assemblies. The standoff features an M3 x 0.5 thread on both ends with a 3.5 mm overall length and a hexagonal body measuring 5 mm across flats for wrench engagement. Machined from Grade 18-8 / 303 stainless steel with a passivated finish, it meets the QQ-S-763 fastener standard. Electronics technicians, field service engineers, and panel builders use this type of hardware when assembling control boards, drive enclosures, and instrumentation panels.

This standoff is suited for metric fastener applications in light-duty electronic assemblies where corrosion resistance and dimensional precision are required. The passivated stainless steel construction makes it appropriate for environments with moderate moisture exposure. Thread length runs 5 to 6 mm per end, providing reliable thread engagement for M3 screws commonly found on circuit board mounting holes. It installs in a single package quantity, making it a practical choice for prototyping, service replacement, or low-volume panel builds.

Key Features

• M3 x 0.5 male thread on both ends for standard metric PCB mounting
• 3.5 mm overall length with length tolerance of -0.15 to +0.15 mm
• Hexagonal body at 5 mm width across flats for wrench or nut driver installation
• Grade 18-8 / 303 stainless steel construction for corrosion resistance
• Passivated finish per QQ-S-763 fastener standard
• Thread length of 5 to 6 mm per end for secure engagement

Compatibility

Designed as a metric male-male hex standoff for circuit board mounting applications requiring M3 x 0.5 thread fasteners in electronic assemblies and control enclosures.

Installation Notes

Install using a 5 mm hex wrench or nut driver. Power down all electrical assemblies and discharge any capacitors before working inside control enclosures or panel boards. Do not overtighten stainless steel standoffs into aluminum or plastic substrates, as galling and thread damage can occur. Follow applicable enclosure and panel-build standards for the equipment type being serviced.
