Electro Hardware MMX1702M06-MSC Hex Standoff M4x0.7 Aluminum

Product Description

The ELECTRO HARDWARE MMX1702M06-MSC is a male-male hex circuit board standoff designed for metric fastening applications in electronics assembly and PCB mounting. This standoff features an M4 x 0.7 thread size on both ends, a 3.5 mm overall length, and a hexagonal body measuring 10 mm across the flats. Manufactured from Grade T-3 aluminum with a clear finish, it meets the QQ-A-225A Comp 2 fastener standard. The hex body profile allows wrench engagement for secure, controlled installation. Thread length options of 8.5 mm, 9 mm, and 9.5 mm provide flexibility for varying board stack heights. This standoff is installed by electronics technicians and field service engineers working on control boards, printed circuit assemblies, and enclosure mounting applications.

This standoff is suited for use in residential and commercial electronic control board assemblies, HVAC control panels, electrical enclosures, and general PCB mounting scenarios where a metric male-to-male threaded spacer is required. The aluminum construction keeps weight minimal while providing sufficient thread engagement strength for low-vibration panel and board mounting. Applications include mounting control boards in equipment enclosures where precise board-to-surface standoff height must be maintained.

Key Features

• M4 x 0.7 metric thread on both ends for male-to-male fastening configurations
• 3.5 mm overall length with a length tolerance of -0.15 mm to 0.15 mm
• Hexagonal body at 10 mm across the flats for wrench-driven installation
• Grade T-3 aluminum construction with clear finish for corrosion resistance in typical indoor environments
• Meets QQ-A-225A Comp 2 fastener standard
• Thread lengths of 8.5 mm, 9 mm, and 9.5 mm to accommodate varied board stack requirements

Compatibility

Designed as an OEM-style metric standoff for circuit board and electronics enclosure mounting applications requiring M4 x 0.7 male-male threaded fasteners.

Installation Notes

Installation is performed by electronics technicians or qualified field service personnel. Always de-energize and discharge the control board or panel before removing or installing standoffs. Use an appropriately sized wrench or nut driver on the hex body to achieve secure seating without overtorquing the aluminum threads. Inspect thread engagement on both ends before applying torque to avoid cross-threading or stripping.
