Electro Hardware MMX1502M06-MSC Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMX1502M06-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces or between stacked boards. The standoff features M3 x 0.5 threading on both ends, an overall length of 3.5 mm, and a 6 mm hex body width across flats. It is machined from Grade T-3 aluminum with a clear finish, meeting QQ-A-225A Comp 2 material standards. Electronics assemblers, PCB fabricators, and electronics maintenance technicians install these fasteners during board assembly and rack-mounting applications.

This standoff is suited for compact PCB assemblies where metric hardware is specified. The 3.5 mm overall length and dual male threads make it appropriate for tight board-to-board or board-to-panel configurations in electronics enclosures, control panels, and instrumentation assemblies. The hex body allows tightening with standard nut drivers or wrenches without slipping. Its aluminum construction keeps weight low while providing adequate thread engagement for light-duty fastening applications.

Key Features

• Dual male M3 x 0.5 threads for board-to-board or board-to-panel mounting
• 3.5 mm overall length suits tight-clearance PCB stack configurations
• 6 mm hex width across flats for standard nut driver or wrench installation
• Grade T-3 aluminum construction with clear finish
• Meets QQ-A-225A Comp 2 material standard
• Length tolerance of -0.150 mm to 0.150 mm for consistent fit

Compatibility

Designed as a metric male-male hex standoff for PCB assemblies and electronic enclosures specifying M3 x 0.5 threaded fasteners with a 3.5 mm overall length.

Installation Notes

Electronics technicians and PCB assemblers install these standoffs using a standard nut driver sized for 6 mm hex fasteners. Discharge static and power down all boards and enclosures before handling PCB hardware. Do not overtighten aluminum standoffs, as the threads can strip under excessive torque. Verify that mating thread depth and board hole clearances match M3 x 0.5 specifications before assembly.
