Electro Hardware MMF1835M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1835M06F16M4 is a male-female hex circuit board standoff designed to create fixed spacing between stacked PCBs or between a circuit board and a mounting surface. Machined from aluminum alloy to QQ-A-225A Comp 2 specification, this standoff features an M4 x 0.7 male thread on one end and an M4 x 0.7 female thread on the other. The hexagonal body measures 6 mm across flats, allowing installation and removal with standard hex tooling. Overall length is 31.53 mm, with a body length of 22.00 mm, a male thread length of 9.53 mm, and a female thread depth of 11.10 mm. Used in electronics assembly, control board mounting, and enclosure builds across HVAC, industrial, and electrical applications.

This standoff suits residential and commercial electronics assembly wherever rigid, repeatable PCB spacing is required. Typical applications include mounting control boards inside HVAC units, panel enclosures, and industrial equipment where vibration resistance and precise standoff height matter. The aluminum construction keeps weight minimal in multi-board assemblies. The bright uncoated finish is appropriate for indoor, non-corrosive environments. Installation is handled by electronics assemblers, controls technicians, and electricians working on panel builds.

Key Features

• M4 x 0.7 male-female thread configuration for stacking or surface mounting PCBs
• Hexagonal body profile - 6 mm across flats - accepts standard hex drivers or wrenches
• Aluminum construction, T3 material grade, meets QQ-A-225A Comp 2 fastener standard
• 31.53 mm overall length with tight length tolerance of -0.150 to 0.150 mm
• Bright uncoated finish suited for dry, indoor enclosure environments
• Lightweight design minimizes added mass in multi-board or stacked assemblies

Compatibility

Designed as an OEM-style metric standoff for circuit board assemblies requiring M4 x 0.7 thread engagement in a hex-body configuration.

Installation Notes

Power down all circuits and discharge any capacitors before handling or installing circuit board standoffs in live panels or control assemblies. Use a properly sized hex driver or wrench matched to the 6 mm flat dimension to avoid rounding the body. Verify thread engagement depth against the mating board thickness before final torque to prevent stripping the aluminum threads. Follow applicable NEC or equipment-manufacturer guidelines for control board mounting clearances and fastener specifications.
