Electro Hardware MMX1545M12MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1545M12MSC-1 is a male-male hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from Grade 2 steel with a zinc-plated finish, this metric standoff meets QQ-S-633 standards for dimensional and material consistency. It features an M5 x 0.8 thread on both ends, a 25 mm overall length, and a 6 mm hex body width across flats. The hex profile allows standard wrench engagement for controlled installation torque. This fastener is suited for electronics assembly, control panel builds, and circuit board mounting applications across HVAC, electrical, and industrial equipment.

This standoff is used wherever dual male-threaded hex standoffs are required to mount or stack printed circuit boards at a fixed offset. Typical applications include control board assemblies in HVAC equipment, electrical enclosures, and industrial electronics. The M5 x 0.8 metric thread size and 25 mm body length make it appropriate for standard metric PCB mounting configurations. Installation is performed by electronics assemblers, electricians, or HVAC technicians working on control board replacement or panel assembly.

Key Features

• Male-male hex standoff for dual-sided circuit board mounting
• M5 x 0.8 metric thread on both ends for standard metric fastener compatibility
• 25 mm overall length with 6 mm width across flats for wrench engagement
• Grade 2 steel construction meets QQ-S-633 fastener standard
• Zinc-plated finish provides corrosion resistance in enclosed panel environments
• Thread length tolerance held to -0.150 to 0.150 mm for consistent fit

Compatibility

Designed as a metric male-male hex standoff for circuit board and panel mounting applications requiring an M5 x 0.8 thread and a 25 mm body length.

Installation Notes

Installation is typically performed by a licensed electrician or qualified electronics technician. Power down and de-energize the control board or panel assembly completely before removing or installing standoffs. Use an appropriately sized wrench or nut driver on the 6 mm hex flats to seat the standoff without over-torquing the PCB mounting holes. Follow applicable NEC guidelines and equipment manufacturer instructions when servicing control boards in HVAC or electrical enclosures.
