Electro Hardware MP433M06F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP433M06F16M3 is a female hex circuit board standoff designed to create precise spacing between PCBs, chassis panels, and stacked board assemblies. Machined from aluminum alloy to material grade T3 and finished with a bright uncoated plain finish, this standoff offers a lightweight, corrosion-resistant solution for electronics assembly and enclosure builds. The M3 x 0.5 internal thread runs fully through the 17 mm body length, accepting a standard M3 screw on each mating surface. The hexagonal body profile measures 4.5 mm across flats, making it easy to torque with a standard hex wrench or nut driver during installation.

This standoff is used in PCB mounting applications where consistent board-to-board or board-to-panel spacing is required. Typical installation scenarios include control board assemblies, HVAC control enclosures, electrical panel sub-assemblies, and industrial electronics chassis builds. The lightweight aluminum construction makes it suitable for weight-sensitive applications. It is installed by electronics assembly technicians, field service electricians, and OEM production staff working with metric hardware systems.

Key Features

• Fully threaded female M3 x 0.5 internal thread through full 17 mm body length
• Hex body profile at 4.5 mm width across flats for wrench-driven installation
• Aluminum construction, material grade T3, for lightweight and corrosion resistance
• Plain bright uncoated finish suitable for indoor electronics environments
• Meets QQ-A-225A Comp 2 fastener standard
• Length tolerance held to -0.13 to 0.13 mm for consistent stack height

Compatibility

Designed as an OEM-style metric standoff for PCB and chassis assemblies using M3 x 0.5 threaded hardware in standard hex standoff configurations.

Installation Notes

Installation is performed by electronics assembly technicians or licensed electricians during board mounting or enclosure assembly. De-energize all equipment completely before handling circuit boards or installing standoffs in live enclosures. Use a nut driver or hex wrench sized for 4.5 mm across flats to seat the standoff without overtightening, which can strip the soft aluminum threads. Follow applicable assembly drawings and torque specifications provided by the equipment manufacturer.
