Electro Hardware MMX1702M12MSC-1 Hex Standoff M5

Product Description

The ELECTRO HARDWARE MMX1702M12MSC-1 is a male-male hex circuit board standoff designed for metric fastening applications in printed circuit board assemblies. Manufactured from Grade 2 steel with a zinc-plated finish meeting QQ-S-633 specifications, this standoff provides reliable electrical isolation and mechanical spacing between boards or between a board and a mounting surface. The M5 x 0.8 thread size on both ends allows direct engagement with mating hardware. The overall length is 3.5 mm, and the hex body measures 10 mm across flats for standard wrench engagement. This hardware is installed by electronics assemblers, PCB technicians, and field service technicians working on control boards in HVAC, electrical, and industrial equipment.

This standoff is suited for use in control board assemblies, enclosure mounting, and panel builds where metric M5 threaded hardware is specified. It is commonly used in residential and light commercial HVAC control boards, electrical panel subassemblies, and industrial equipment requiring secure, repeatable board-to-surface spacing. The zinc-plated steel construction makes it appropriate for indoor environments where moderate corrosion resistance is needed. Single-piece packaging makes it practical for service replacement or low-volume repair work.

Key Features

• M5 x 0.8 male threads on both ends for direct metric fastening
• 3.5 mm overall length with hex body shape for wrench-driven installation
• 10 mm width across flats for standard metric wrench or socket engagement
• Grade 2 steel construction with zinc-plated finish per QQ-S-633
• Length tolerance of -0.150 to 0.150 mm for consistent stack-up control
• UNSPSC Code 31161816 for procurement classification

Compatibility

Designed as a metric M5 x 0.8 male-male hex standoff for use in circuit board assemblies and enclosure builds where QQ-S-633 compliant zinc-plated steel hardware is specified.

Installation Notes

Installation is performed by PCB assemblers or field service technicians using a standard metric wrench or socket sized for a 10 mm hex. Ensure mating threads are clean and free of debris before engagement. Do not overtighten, as the compact 3.5 mm body length provides limited torque margin. De-energize all circuits and discharge any stored energy before working on control boards or panel assemblies.
