Electro Hardware MMF1301M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1301M06F16M3 is an aluminum male-female hex circuit board standoff designed for metric M3x0.5 thread applications. It provides a rigid, electrically isolated spacer between PCB layers or between a board and a chassis. The hex body shape allows standard wrench engagement for precise installation without slipping. With an overall length of 9.76 mm, a male thread length of 4.76 mm, a female thread depth of 6.40 mm, and a body length of 5.00 mm, this standoff suits tight PCB stack tolerances. The uncoated aluminum construction meets QQ-A-225A Comp 2 material standards, making it appropriate for electronics assembly environments where corrosion exposure is minimal.

This standoff is used in PCB mounting and stacking applications across industrial controls, HVAC control boards, electrical enclosures, and commercial electronics assemblies. It is installed during board fabrication, panel assembly, or field repair by electronics technicians, control board assemblers, and licensed electricians working with panel-mounted circuit boards. The 4.5 mm width across flats fits standard metric hex tooling. It is sold individually with a minimum order quantity of 10 units, making it suitable for both small repair jobs and volume assembly runs.

Key Features

• Male-female thread configuration allows stacking or chassis mounting in a single fastener
• M3x0.5 metric thread on both male and female ends ensures compatibility with standard M3 hardware
• Hex body shape with 4.5 mm width across flats accepts standard metric wrenches or hex drivers
• Aluminum construction, Material Grade T3, meets QQ-A-225A Comp 2 specification
• Bright uncoated finish suitable for indoor electronics and control board environments
• Length tolerance of -0.150 to 0.150 mm supports precise PCB stack height requirements

Compatibility

Designed for use with M3x0.5 metric threaded hardware in PCB mounting and stacking assemblies. No specific board or chassis model compatibility was provided by the manufacturer for this part number.

Installation Notes

Install and remove using a metric hex wrench or nut driver sized for 4.5 mm across flats. Power down all equipment and discharge any stored energy before servicing live control boards or panel-mounted assemblies. Avoid overtightening, as aluminum threads can strip or gall when excessive torque is applied. Follow applicable assembly standards and enclosure wiring codes, including NEC requirements, when installing standoffs inside electrical panels or enclosures.
