Electro Hardware MMF1813M06F16M4 Hex Standoff M4x0.7

Product Description

The ELECTRO HARDWARE MMF1813M06F16M4 is an aluminum male-female hex circuit board standoff designed to create precise spacing between stacked PCBs or between a PCB and an enclosure panel. The standoff features an M4x0.7 threaded male post on one end and a threaded female receptacle on the other, allowing boards to be fastened securely while maintaining a defined separation. The body measures 11.00 mm in length with a hexagonal profile across a 6.00 mm flat-to-flat width, making it wrench-accessible during assembly. Manufactured from T3 aluminum to the QQ-A-225A Comp 2 fastener standard with a bright uncoated finish, this standoff suits electronics assembly work where lightweight hardware and corrosion resistance are priorities.

This standoff is used in PCB assembly, control panel construction, and electronics enclosure builds across industrial, commercial, and light-duty electronic applications. The metric M4x0.7 thread sizing fits standard metric board layouts. Technicians and assemblers installing multi-board rack systems, motor drive panels, HVAC control boards, or custom enclosure builds will find this standoff appropriate for maintaining consistent board-to-board or board-to-chassis clearance. The hex body shape allows installation and removal with standard nut drivers or open-end wrenches without slipping.

Key Features

• Male-female thread configuration allows stacking or panel-mount board installations
• M4x0.7 metric thread on both male post and female receptacle
• Hexagonal body with 6.00 mm width across flats for wrench-assisted torquing
• T3 aluminum construction per QQ-A-225A Comp 2 standard - lightweight and corrosion-resistant
• Bright uncoated finish - no coating thickness to account for in tight tolerance assemblies
• Length tolerance of -0.150 to +0.150 mm for consistent board spacing across multi-standoff layouts

Compatibility

Designed as a standard metric male-female hex standoff for circuit board and enclosure assemblies using M4x0.7 threaded fastener patterns.

Installation Notes

Installation is performed by electronics technicians and panel assemblers using a nut driver or open-end wrench sized to the 6 mm hex body. Always de-energize and discharge any boards or assemblies before installing or removing standoffs. Finger-tighten first to confirm thread engagement on both ends before applying tool torque. Do not overtighten aluminum standoffs against PCB mounting pads, as the threads and board material can be damaged by excessive force.
