Electro Hardware MMF1833M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1833M06F16M4 is an aluminum male-female hex circuit board standoff designed to space and stack PCBs within electronic enclosures, control panels, and equipment chassis. It carries an M4x0.7 thread on both the male and female ends and measures 30.53 mm (approximately 1.20 inches) in overall length with a hex body width across flats of 6 mm (approximately 0.24 inches). The body length is 21.00 mm, the male thread length is 9.53 mm, and the female thread depth is 11.10 mm. Machined from T3-grade aluminum and supplied bright and uncoated, it meets the QQ-A-225A Comp 2 standard. Electricians, electronics technicians, and panel builders use these standoffs during PCB assembly and enclosure wiring work.

This standoff is suited for residential and commercial electronic control assemblies where metric M4 threaded mounting points are required. Typical applications include circuit board stacking in HVAC control boards, industrial enclosures, motor drive panels, and custom electronics chassis. The hex body allows wrench tightening without slipping, making it practical in confined panel spaces. It is sold individually with a minimum order quantity of 10 units, which suits both prototype builds and small production runs.

Key Features

• M4x0.7 metric thread on both male and female ends for double-sided PCB mounting
• Hex body shape with 6 mm width across flats for wrench or nut driver installation
• T3-grade aluminum construction - lightweight and corrosion-resistant for panel environments
• Bright uncoated finish meets QQ-A-225A Comp 2 fastener standard
• Length tolerance of -0.150 mm to +0.150 mm for consistent board spacing
• Low individual unit weight (approximately 0.005 pounds) supports high-density board layouts

Compatibility

Designed as an OEM-style metric standoff for circuit boards and enclosures requiring M4x0.7 threaded male-female hex spacers.

Installation Notes

Installation is performed by electronics technicians, electricians, or panel builders. Power down and de-energize all circuits in the enclosure before mounting or removing circuit boards. Use a 6 mm hex wrench or nut driver on the hex body to achieve a snug fit - do not overtighten aluminum fasteners, as the threads can strip. Ensure mating board clearance holes are sized correctly for M4 hardware before assembly.
