Electro Hardware MP437M06F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP437M06F16M3 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from aluminum alloy to material grade T3 and finished with a bright, uncoated plain surface, this standoff accepts an M3 x 0.5 threaded fastener. The overall length is 19 mm (approximately 0.748 inches), with a fully threaded interior at 19 mm thread depth and a 4.5 mm (approximately 0.177 inches) hex width across flats. The hexagonal body allows reliable torquing without marring. This hardware is produced to the QQ-A-225A Comp 2 specification, making it a consistent choice for controlled assembly environments.

This standoff is used in electronics manufacturing, PCB assembly, and control panel fabrication across HVAC, industrial controls, and commercial electrical equipment. The M3 x 0.5 metric thread size suits light-gauge PCB stacking configurations where consistent board-to-board or board-to-chassis clearance is required. Its aluminum construction keeps weight minimal in densely populated assemblies. Technicians and assemblers installing control boards, drive modules, or relay panels will find this standoff compatible with standard metric hardware workflows.

Key Features

• Female M3 x 0.5 fully threaded interior for standard metric fastener acceptance
• 19 mm overall length with full 19 mm thread depth for maximum thread engagement
• Hexagonal body at 4.5 mm width across flats for wrench-driven installation
• Aluminum construction, material grade T3, for lightweight and corrosion-resistant performance
• Plain bright uncoated finish maintains dimensional precision without added coating buildup
• Manufactured to QQ-A-225A Comp 2 specification for consistent material quality

Compatibility

Designed as a metric M3 x 0.5 female hex standoff for PCB mounting and electronic chassis assembly applications requiring aluminum hardware to QQ-A-225A Comp 2 standards.

Installation Notes

Installation is performed by electronics technicians or electricians during PCB mounting or control panel assembly. Ensure mating fasteners are M3 x 0.5 metric thread to prevent cross-threading. Use an appropriately sized hex driver or wrench sized for 4.5 mm flats to seat the standoff without deforming the aluminum body. Power down and de-energize all circuits before working on any board or panel assembly.
