Electro Hardware MMX1545M12-MSC Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMX1545M12-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, panels, or chassis components in electronic assemblies. Threaded M4 x 0.7 on both ends, this standoff has a 25 mm overall length and a hexagonal body measuring 6 mm across flats, making it easy to drive with a standard wrench or hex socket. It is manufactured from Grade 2 steel with a zinc-plated finish that provides corrosion resistance in typical indoor environments. The QQ-S-633 fastener standard governs its material and finish requirements. Electronics assemblers, panel builders, and field service technicians working on control boards and enclosures are the primary installers.

This standoff is suited for use in circuit board mounting applications where a threaded male post is required on both ends to accept a mating nut or threaded receiver. Typical use cases include spacing control boards inside HVAC equipment, electrical enclosures, and industrial control panels. The metric M4 x 0.7 thread pattern is common in PCB and panel hardware across commercial and residential equipment. Thread length options of 8.5 mm, 9 mm, and 9.5 mm provide minor adjustment flexibility during assembly.

Key Features

• Thread length range of 8.5 mm to 9.5 mm
• Sold individually with a minimum order quantity of one

Compatibility

Designed as an OEM-style replacement or supplemental hardware for circuit board standoff applications requiring M4 x 0.7 male-male metric hex fasteners in electronic and control panel assemblies.

Installation Notes

Installation requires a wrench or hex socket sized for 6 mm across flats. De-energize all equipment completely before handling circuit boards or internal panel hardware. Avoid over-tightening, which can strip the M4 threads or crack PCB mounting holes. Follow applicable enclosure and panel wiring codes when working inside electrical control cabinets.
