Electro Hardware MMX1615M12-MSC Hex Standoff M4x0.7 10mm

Product Description

The ELECTRO HARDWARE MMX1615M12-MSC is a male-male hex circuit board standoff designed to create fixed spacing between stacked PCBs or between a circuit board and a chassis panel. Threaded on both ends with an M4 x 0.7 thread, this standoff accepts a mating fastener on each side to secure boards in a rigid, repeatable position. The overall length is 10 mm, the body is hex-shaped with a width across flats of 8 mm, and the part is manufactured from Grade 2 steel with a zinc-plated finish that meets QQ-S-633 requirements. Electronics assembly technicians and panel builders commonly install this fastener during board mounting and enclosure assembly work.

This standoff is suited for metric-threaded circuit board assemblies in electronic control panels, HVAC control boards, industrial enclosures, and similar applications where precise board-to-board or board-to-chassis spacing is required. The M4 x 0.7 thread pitch is a standard metric size found across a wide range of PCB and enclosure hardware. Thread length options of 8.5 mm, 9 mm, or 9.5 mm provide fitment flexibility across different board thicknesses and mounting stack heights.

Key Features

• M4 x 0.7 metric thread on both male ends for standard metric fastener compatibility
• 10 mm overall length with a hex body for wrench-driven installation and removal
• 8 mm width across flats allows use with standard metric wrenches or nut drivers
• Grade 2 steel construction provides reliable mechanical strength for panel and PCB mounting
• Zinc-plated finish meets QQ-S-633 standard for corrosion resistance in indoor enclosure environments
• Thread lengths of 8.5 mm, 9 mm, and 9.5 mm accommodate varied board and chassis thicknesses

Compatibility

Designed as a standard metric male-male hex standoff for use in circuit board assemblies, electronic control enclosures, and panel mounting applications requiring M4 x 0.7 threaded hardware.

Installation Notes

Install and remove using a metric wrench or nut driver sized for an 8 mm hex. De-energize and lockout the equipment before handling any circuit boards or control panel components. Avoid over-torquing, as Grade 2 steel standoffs in metric sizes can be damaged by excessive force in thin PCB mounting holes. Follow applicable electrical codes and equipment manufacturer guidelines when servicing control boards in HVAC or industrial panels.
