Electro Hardware MMF1315M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1315M06F16M3 is a male-female hex circuit board standoff designed to create fixed spacing between stacked PCBs or between a circuit board and a chassis. The standoff features an M3 x 0.5 thread, a hex body measuring 4.5 mm width across flats, and an overall length of 16.76 mm. The male end threads into a mating female standoff or mounting hole, while the female end accepts the next fastener in the stack. Manufactured from aluminum alloy T3 with a bright, uncoated finish, this standoff meets the QQ-A-225A Comp 2 material standard. Electronics assemblers and field service technicians install these during board-level assembly and serviceability work.

This standoff is suited for metric-threaded PCB mounting applications in electronics enclosures, control panels, and industrial assemblies where consistent board-to-board or board-to-chassis standoff height is required. The compact hex profile allows standard hex driver or wrench installation in tight board layouts. It is commonly used in HVAC control boards, low-voltage electronics, and OEM electronic assemblies that require a durable, lightweight non-ferrous spacer.

Key Features

• Male-female configuration for stackable, multi-board or board-to-chassis mounting
• M3 x 0.5 metric thread on both ends for compatibility with standard M3 hardware
• Hex body profile allows installation with standard hex drivers or open-end wrenches
• Aluminum T3 construction provides lightweight, corrosion-resistant performance
• Bright uncoated finish meets QQ-A-225A Comp 2 material specification
• Length tolerance of -0.150 to 0.150 mm for consistent stack height

Compatibility

Designed as a metric M3 x 0.5 male-female hex standoff suitable for PCB mounting applications requiring a 16.76 mm overall standoff height with standard M3 threaded hardware.

Installation Notes

Installation is typically performed by electronics assemblers or technicians during board assembly or service. Power down and de-energize all circuits before installing or removing standoffs on live control boards. Use an appropriately sized hex driver or open-end wrench on the 4.5 mm hex flats - avoid pliers that may deform the aluminum body. Follow applicable IPC assembly standards and the equipment manufacturer's torque guidance for M3 aluminum fasteners.
