Electro Hardware MMX1702M12-MSC Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMX1702M12-MSC is a male-male hex circuit board standoff designed to create fixed spacing between circuit boards or between a board and a mounting surface. Threaded on both ends with an M4 x 0.7 metric thread, this standoff features a 3.5 mm overall length and a hexagonal body measuring 10 mm width across flats. Constructed from Grade 2 steel with a zinc-plated finish, it meets QQ-S-633 fastener standards. Thread length options of 8.5 mm, 9 mm, and 9.5 mm provide installation flexibility. Electronics assembly technicians and PCB service professionals are the primary installers of this hardware.

This standoff is suited for metric circuit board assemblies in industrial, commercial, and consumer electronics applications where a rigid, conductive spacer is required between stacked boards or between a board and an enclosure panel. The compact 3.5 mm body length makes it appropriate for dense PCB layouts where clearance is limited. Its zinc-plated steel construction offers corrosion resistance in standard indoor environments.

Key Features

• M4 x 0.7 metric male-male threading on both ends for secure board-to-board or board-to-chassis attachment
• Hexagonal body at 10 mm width across flats allows wrench engagement for precise torque application
• Grade 2 steel construction with zinc-plated finish for durability and corrosion resistance
• Meets QQ-S-633 fastener standard
• Length tolerance of -0.150 mm to 0.150 mm for consistent, repeatable stack height
• Metric system of measurement for compatibility with international PCB designs

Compatibility

Designed for use in metric circuit board assemblies requiring M4 x 0.7 male-male hex standoffs with a 3.5 mm body length and 10 mm hex width across flats.

Installation Notes

Installation is performed by electronics assembly technicians using an appropriately sized hex wrench or nut driver sized for the 10 mm width across flats. Power down and discharge all capacitors in the assembly before handling circuit boards or installing standoffs. Do not overtighten, as excessive torque on small metric fasteners can strip threads or stress PCB mounting holes. Follow the assembly drawing or board manufacturer specifications for proper standoff placement and stack height.
