Electro Hardware MMX1535M06-MSC Hex Standoff M3x0.5 20mm

Product Description

The ELECTRO HARDWARE MMX1535M06-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, panels, or chassis components in electronic assemblies. Machined from aluminum alloy at Grade T-3 with a clear finish, this standoff accepts M3 x 0.5 metric threads on both ends. The overall length is 20 mm with a 6 mm hex width across flats, allowing standard hex drivers or wrenches to seat the fastener securely. It is installed by electronics assembly technicians, field service engineers, and PCB rework specialists across industrial, commercial, and consumer electronics applications.

This standoff is suited for metric PCB mounting configurations where a male-to-male threaded spacer is required to stack boards or mount a board to a panel at a fixed 20 mm standoff height. The hex body shape simplifies installation in confined board layouts where a driver is needed for precise torque control. Grade T-3 aluminum keeps the weight low while providing adequate structural integrity for static mounting applications in control panels, enclosures, and electronics assemblies across HVAC controls, electrical panels, and similar trade equipment.

Key Features

• M3 x 0.5 male threads on both ends for full metric compatibility
• 20 mm overall body length with a length tolerance of -0.150 to 0.150 mm
• 6 mm hex width across flats for wrench or hex driver installation
• Grade T-3 aluminum construction with clear finish for corrosion resistance in light-duty environments
• Meets QQ-A-225A Comp 2 aluminum alloy material standard
• Thread lengths of 5 mm and 6 mm on respective ends for secure thread engagement

Compatibility

Designed as an OEM-style replacement or supplemental fastener for metric PCB and panel mounting applications requiring M3 x 0.5 male-male hex standoffs at a 20 mm standoff height.

Installation Notes

Installation is performed by electronics assembly or service technicians. Always de-energize and discharge any board or assembly before installing or removing standoffs to prevent electrostatic discharge damage or electrical hazard. Use a properly sized hex driver or open-end wrench on the 6 mm flats to avoid rounding the hex body. Do not exceed the structural load rating of the aluminum alloy when stacking multiple boards on a single standoff column.
