Electro Hardware MMF1329M06F16M3 Hex Standoff M3

Product Description

The ELECTRO HARDWARE MMF1329M06F16M3 is a male-female hex circuit board standoff designed to create precise, rigid spacing between PCB layers or between a board and a mounting surface. Machined from T3 aluminum with a bright uncoated finish, this standoff meets the QQ-A-225A Comp 2 material standard. It features an M3 x 0.5 thread on both ends - one male, one female - with an overall length of 23.76 mm and a hexagonal body measuring 4.50 mm across the flats. Electronics assembly technicians and PCB fabricators install this fastener where lightweight, corrosion-resistant spacing hardware is required in production or field assemblies.

This standoff is used in electronics manufacturing and PCB assembly environments, including control board assemblies found in HVAC equipment, industrial panels, and consumer electronics. The metric M3 x 0.5 thread sizing makes it compatible with standard metric PCB mounting hardware. The hex body allows installation and removal with standard hex drivers or nut drivers without marring surrounding board components. It is appropriate for both production-line builds and field-service PCB replacements where OEM-style standoff hardware must be sourced.

Key Features

• M3 x 0.5 male-female thread configuration for through-stack PCB mounting
• Hexagonal body profile at 4.50 mm across flats for tool-driven installation and removal
• T3 aluminum construction meeting QQ-A-225A Comp 2 material standard for lightweight, corrosion-resistant performance
• Overall length of 23.76 mm with a body length of 19.00 mm and thread length of 4.76 mm
• Length tolerance of -0.150 mm to +0.150 mm for consistent stack height in multi-board assemblies
• Bright uncoated finish suitable for applications where surface coating is not required

Compatibility

Designed as an OEM-style metric standoff for PCB and circuit board assemblies using M3 x 0.5 threaded mounting hardware.

Installation Notes

Installation is performed by electronics assembly technicians or field service personnel working on PCB-mounted control systems. Disconnect power to the equipment before handling circuit boards or standoff hardware. Use a metric hex driver or nut driver sized to the 4.50 mm across-flats dimension to seat the standoff without over-torquing the aluminum threads. Follow applicable assembly standards and equipment manufacturer guidelines when replacing or installing PCB standoffs in live control panels.
