Electro Hardware MMF1831M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1831M06F16M4 is an aluminum male-female hex circuit board standoff used to create precise spacing between stacked PCBs or between a circuit board and a mounting surface. The male thread engages the receiving board or enclosure while the female thread accepts the next fastener or board in the stack. The standoff measures 29.53 mm (1.16 inches) in overall length with a 6.00 mm hex body width across flats, making it compatible with standard hex drivers and nut drivers. It is uncoated bright aluminum meeting QQ-A-225A Comp 2 material standards. Electronics assemblers, instrumentation technicians, and control panel builders install these during board-level assembly work.

This standoff is suited for metric threaded PCB assemblies requiring M4 x 0.7 thread engagement. The hex body shape allows torque-controlled installation without slipping, and the uncoated aluminum finish is appropriate for indoor electronics enclosures, control panels, and instrumentation assemblies where corrosion exposure is minimal. The 20.00 mm body length provides consistent board-to-board or board-to-chassis clearance in layered PCB configurations. This part is sold individually with a minimum order quantity of 10 units.

Key Features

• M4 x 0.7 metric thread on both male and female ends for standard PCB hardware compatibility
• Hex body shape with 6.00 mm width across flats for wrench or nut driver installation
• Aluminum construction per QQ-A-225A Comp 2 with T3 material grade
• Overall length of 29.53 mm (1.16 inches) with a length tolerance of -0.150 to +0.150 mm
• 20.00 mm body length with 9.53 mm male thread length and 11.10 mm female thread depth
• Bright uncoated finish - no coating buildup to affect thread fit

Compatibility

Designed as a standard metric male-female hex standoff for M4 x 0.7 threaded circuit board assemblies and enclosure mounting applications.

Installation Notes

Install with a 6 mm hex nut driver or open-end wrench. Apply consistent, controlled torque to avoid stripping the aluminum threads - do not use impact drivers. Ensure the mating female thread is fully engaged before torquing the male end into the receiving surface. Disconnect and de-energize all equipment before performing board-level assembly or standoff replacement work.
