Electro Hardware MM1401M12-MSC Hex Standoff 4-40 1/8 in

Product Description

The ELECTRO HARDWARE MM1401M12-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces or between stacked boards. Manufactured from Grade 2 steel with a zinc-plated finish, this standoff meets QQ-S-633 standards and provides reliable mechanical separation in electronic enclosures and control panel assemblies. The hex body profile allows installation and removal with standard hex tools. At 0.125 inches overall length and 0.250 inches width across flats, it is suited for compact, low-profile circuit board mounting applications where minimal stack height is required.

This standoff is used in residential and commercial control board assemblies, HVAC system electronics, electrical panel builds, and general electronic enclosure fabrication. The 4-40 thread size is common in circuit board mounting applications across a wide range of light-duty electronic hardware. It is typically installed by electricians, electronics technicians, HVAC controls specialists, and experienced DIYers working on PCB assemblies or control enclosures.

Key Features

• Male-male thread configuration allows stacking or spacing of circuit boards
• Grade 2 steel construction meets QQ-S-633 fastener standard
• Zinc-plated finish provides basic corrosion resistance for indoor enclosure use
• Hex body shape accepts standard hex drivers and wrenches for secure installation
• Compact 0.125 inch overall length suited for tight PCB stack clearances
• 4-40 unified thread size is widely compatible with standard circuit board hardware

Compatibility

Designed as an OEM-style replacement or standard hardware component for circuit board standoff applications using 4-40 threaded mounting points in electronic enclosures and control assemblies.

Installation Notes

Installation is typically performed by electricians or electronics technicians. Always de-energize and discharge any circuit board assembly before installing or removing standoffs. Use a properly sized hex driver or nutdriver to avoid damaging the hex flats or PCB mounting pads. Follow applicable NEC guidelines when working inside energized electrical enclosures.
