Electro Hardware MMX1507M12MSC-1 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMX1507M12MSC-1 is a male-male hex circuit board standoff designed to create precise spacing between PCB layers and mounting surfaces in electronic assemblies. It features an M4 x 0.7 thread size on both ends, a 6 mm overall length, and a 6 mm hex body width across flats. The standoff is manufactured from Grade 2 steel with a zinc-plated finish that meets QQ-S-633 standards, providing corrosion resistance in typical indoor electronic enclosure environments. Electricians, control board technicians, and electronics assembly professionals use this type of hardware when building or servicing control panels, circuit board assemblies, and enclosure sub-assemblies.

This standoff is suited for metric-threaded circuit board mounting applications where male-to-male thread engagement is required on both sides of the fastener. The hex body profile allows for standard hex driver or wrench installation, making it practical for tight PCB enclosures. It is commonly installed in HVAC control boards, electrical panel sub-assemblies, and industrial electronics where consistent board-to-surface standoff height is critical for clearance, vibration resistance, and serviceability.

Key Features

• M4 x 0.7 male threads on both ends for secure dual-sided PCB engagement
• 6 mm overall length with thread lengths of 8.5 mm, 9 mm, and 9.5 mm available
• Hexagonal body profile at 6 mm width across flats for wrench or socket installation
• Grade 2 steel construction with zinc plating per QQ-S-633 for corrosion resistance
• Length tolerance of -0.15 mm to 0.15 mm for consistent, repeatable board spacing
• Metric system of measurement; UNSPSC Code 31161816

Compatibility

Designed as an OEM-style replacement or service hardware for metric M4 x 0.7 circuit board standoff applications in electronic enclosures and control panel assemblies.

Installation Notes

Installation is performed by electronics assembly technicians or licensed electricians working on control panel sub-assemblies. Always de-energize and lock out the control panel or equipment before servicing circuit board hardware. Use a correctly sized hex driver or wrench sized for 6 mm across flats to avoid rounding the hex body. Do not overtighten, as this can stress the PCB mounting holes or distort the standoff thread.
