Electro Hardware MMF1309M06F16M3 Hex Standoff M3

Product Description

The ELECTRO HARDWARE MMF1309M06F16M3 is a male-female hex circuit board standoff designed to create precise, rigid spacing between PCBs and mounting surfaces in electronic assemblies. Machined from T3-grade aluminum with a bright uncoated finish, it offers a lightweight, corrosion-resistant solution for metric fastening applications. The standoff features an M3 x 0.5 thread on both the male and female ends, with an overall length of 13.76 mm (approximately 0.54 inches) and a hex body width across flats of 4.5 mm (approximately 0.18 inches). It meets the QQ-A-225A Comp 2 aluminum material standard, making it appropriate for applications where material traceability is required.

This standoff is suited for use in residential and commercial electronic control assemblies, HVAC control boards, electrical enclosures, and industrial PCB mounting applications. Installers and technicians use hex standoffs like this one when stacking or spacing circuit boards at a fixed height while maintaining a secure threaded connection at both ends. The hex body profile allows for wrench tightening without marring adjacent board surfaces. Sold individually, with a minimum order quantity of 10 units.

Key Features

• Male-female configuration allows stacking of circuit boards with a continuous threaded connection
• M3 x 0.5 metric thread on both ends with a thread depth of 6.40 mm on the female end and thread length of 4.76 mm on the male end
• Hex body shape with 4.5 mm width across flats for wrench engagement during installation
• T3-grade aluminum construction with bright uncoated finish keeps weight minimal
• Meets QQ-A-225A Comp 2 material standard for aluminum alloy traceability
• Length tolerance of -0.150 to 0.150 mm for consistent board spacing

Compatibility

Designed as a metric M3 x 0.5 hex standoff for use in PCB mounting, electronic control board assemblies, and enclosure hardware applications requiring QQ-A-225A Comp 2 compliant aluminum fasteners.

Installation Notes

Installation is typically performed by electronic technicians or electricians working on control board assemblies. Power down and de-energize all equipment before servicing any circuit board or control enclosure. Use an appropriately sized hex wrench or nut driver to engage the 4.5 mm hex body - do not overtighten, as aluminum threads are susceptible to galling and cross-threading. Follow applicable NEC guidelines when installing or replacing control board hardware within electrical enclosures.
