Electro Hardware MMX1445M12MSC-1 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMX1445M12MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, panels, and enclosure surfaces in electronic assemblies. Machined from Grade 2 steel with a zinc-plated finish, this standoff meets QQ-S-633 fastener standards. It carries an M4 x 0.7 thread on both ends, a 25 mm overall length, and a 5 mm hex body width across flats. Thread length ranges from 8.5 mm to 9.5 mm. Electronics assemblers, equipment technicians, and board-level service professionals install these fasteners during PCB mounting, chassis assembly, and control panel builds.

This standoff is suited for metric-thread circuit board mounting applications in both commercial and industrial electronic assemblies. It is commonly used in control panels, HVAC equipment boards, electrical enclosures, and other assemblies requiring rigid, threaded board standoffs. The hex body allows installation and removal with a standard wrench or hex driver without marring adjacent components. Single-piece packaging makes it easy to source individual replacement fasteners for service and repair work.

Key Features

• M4 x 0.7 metric thread on both male ends for secure double-sided fastening
• 25 mm overall length with a 25 mm hex body for consistent PCB spacing
• 5 mm width across flats for easy wrench or driver installation
• Grade 2 steel construction with zinc-plated finish for corrosion resistance
• Meets QQ-S-633 fastener standard
• Thread length range of 8.5 mm to 9.5 mm accommodates standard board thicknesses

Compatibility

Designed as an OEM-style metric hex standoff for circuit board and panel mounting applications requiring M4 x 0.7 threaded fasteners in electronic assemblies.

Installation Notes

Installation is typically performed by electronics technicians or electricians during board mounting or enclosure assembly. Power down and de-energize all circuits before working inside any control panel or electrical enclosure. Use a 5 mm wrench or appropriate hex driver to seat the standoff without overtightening, which can strip the metric threads or crack the board. Follow applicable NEC guidelines when installing standoffs inside electrical enclosures.
