Electro Hardware MMX1745M12MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1745M12MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between stacked circuit boards or between a board and a chassis. Manufactured from Grade 2 steel with a zinc-plated finish meeting QQ-S-633 standards, this standoff provides reliable corrosion resistance in typical electronic enclosure environments. The metric M5 x 0.8 thread runs on both ends, with a hexagonal body that accepts a standard wrench or socket for secure torque-free hand tightening during board assembly. The overall length is 25 mm with a 10 mm width across flats, making it suited for medium-duty PCB mounting applications.

This standoff is used in circuit board assembly, industrial control panels, and electronic enclosures where metric fasteners are specified. It is appropriate for both new builds and field-service replacement in residential and commercial HVAC control boards, electrical panels, and similar equipment requiring rigid, precise board-to-board or board-to-chassis separation. Installation is typically performed by electronics technicians, electricians, or HVAC service technicians working with control board assemblies.

Key Features

• Male-male hex body accepts wrench or socket for secure installation without marring board surfaces
• M5 x 0.8 metric thread on both ends for wide compatibility with metric-threaded PCB hardware
• Grade 2 steel construction with zinc-plated finish meets QQ-S-633 fastener standards
• Hexagonal body shape allows precise torque application and prevents rotation during assembly
• 25 mm overall length provides consistent board spacing in control panel stack configurations

Compatibility

Designed as an OEM-style replacement or new-installation metric standoff for circuit board assemblies requiring M5 x 0.8 male-male hex standoffs with a 25 mm overall length.

Installation Notes

Power down all equipment and discharge any capacitors before working inside control panels or on circuit board assemblies. Use an appropriately sized metric wrench or nut driver on the 10 mm hex body to seat the standoff without over-torquing and stressing the board substrate. Inspect mating threads on both the board and chassis for damage or contamination before installation. Follow applicable NEC or equipment manufacturer guidelines for enclosure reassembly after service.
