Electro Hardware MMX1515M06-MSC Hex Board Standoff M3

Product Description

The ELECTRO HARDWARE MMX1515M06-MSC is a male-to-male hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from Grade T-3 aluminum with a clear finish, it meets the QQ-A-225A Comp 2 fastener standard. The standoff features an M3 x 0.5 thread on both ends, a 10 mm overall length, and a 6 mm hex width across flats. The hex body profile allows installation and removal with standard hex drivers or open-end wrenches, making it suitable for production and field service environments. Electronics assemblers, industrial maintenance technicians, and panel builders typically install this hardware.

This standoff is used in PCB mounting applications where a threaded male post is required on both ends to stack boards or attach a cover panel. It is suited for metric-threaded assemblies in industrial control panels, HVAC control board housings, electrical enclosures, and similar equipment. The aluminum construction keeps weight low and resists corrosion in typical indoor electronic environments. Its compact 10 mm OAL makes it appropriate for tight board spacing requirements.

Key Features

• Male-to-male threaded ends accept M3 x 0.5 metric fasteners on both sides
• Hex body profile at 6 mm width across flats allows torque application with standard wrenches or hex drivers
• Grade T-3 aluminum construction keeps weight low and resists corrosion
• Clear finish meets QQ-A-225A Comp 2 fastener standard
• Length tolerance held to -0.150 mm to 0.150 mm for consistent board spacing

Compatibility

Designed as an OEM-style replacement or production-use standoff for metric PCB assemblies requiring M3 x 0.5 male-to-male hex standoffs with a 10 mm overall length.

Installation Notes

Installation is typically performed by electronics assemblers or maintenance technicians working on circuit board enclosures. Power down and de-energize all equipment completely before removing or installing circuit board hardware. Use a correctly sized hex driver or open-end wrench matched to the 6 mm flats to avoid rounding the standoff body. Follow applicable assembly drawings and torque specifications provided by the equipment manufacturer, as none are specified for this hardware alone.
