Electro Hardware MM1405M09MSC-1 Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE MM1405M09MSC-1 is a male-male hex circuit board standoff machined from 18-8 grade 303 stainless steel with a passivated finish. It uses a 6-32 thread on both ends and measures 0.1875 inches (3/16 inches) overall length with a 0.25-inch (1/4-inch) width across flats. The hex body shape allows installation and removal with a standard hex wrench or nutdriver. The passivated finish improves corrosion resistance, making this standoff suitable for electronics assemblies exposed to humidity or light chemical environments. Electronics assemblers, field service technicians, and PCB-level repair professionals install this type of fastener to maintain fixed spacing between circuit boards and chassis or between stacked boards.

This standoff is used in circuit board mounting applications where a rigid male-to-male threaded connection is required at both ends. Typical installations include PCB stack-ups in control panels, HVAC control boards, relay panels, and industrial electronics enclosures. The 6-32 thread is one of the most common thread sizes in U.S. electronics hardware, and the 3/16-inch overall length suits very low-profile board-to-board or board-to-chassis spacing requirements. The stainless steel construction meets the QQ-S-763 fastener standard.

Key Features

• Male-male hex standoff provides threaded connection on both ends for secure board mounting
• 18-8 grade 303 stainless steel construction for corrosion resistance and durability
• Passivated finish per QQ-S-763 standard for enhanced surface corrosion protection
• 6-32 thread size — widely compatible with standard U.S. electronics hardware
• Hex body shape accepts standard nutdriver or hex wrench for controlled installation
• Compact 3/16-inch overall length for low-profile PCB spacing applications

Compatibility

Designed for circuit board mounting applications requiring a 6-32 male-male threaded hex standoff with a 3/16-inch overall length and 1/4-inch width across flats. Suitable for use in any assembly that accepts this thread size and standoff geometry.

Installation Notes

Installation is performed by electronics technicians or assemblers using a nutdriver or hex wrench sized to the 1/4-inch width across flats. Always power down and de-energize the circuit board assembly before installing or removing standoffs. Avoid over-torquing, as the short body length leaves minimal thread engagement margin. Follow applicable workmanship standards for the assembly environment when installing into production electronics.
