Electro Hardware 1369M06F16256 Hex Standoff 2-56 2-1/4 in

Product Description

The ELECTRO HARDWARE 1369M06F16256 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, enclosure panels, and mounting surfaces in electronic assemblies. Machined from aluminum alloy T3 per the QQ-A-225A Comp 2 fastener standard, this standoff features a 2-56 unified thread on both ends — a male thread on one end and a female threaded bore on the other — allowing boards to be stacked or mounted at a consistent 2-1/4 inch body length. The hexagonal body profile measures 3/16 inch across flats, making it compatible with standard nut drivers and hex sockets. It installs and services cleanly without special tooling, which suits technicians working inside control panels, automation enclosures, and PCB assemblies.

This standoff is suited for light-duty electronic mounting applications in residential and commercial control panels, HVAC circuit board assemblies, industrial enclosures, and general electronics fabrication. The 2-56 thread size is a fine-pitch standard commonly found on small-format PCBs and low-profile mounting hardware. The bright uncoated aluminum finish keeps the part lightweight while maintaining dimensional stability. Electricians, control panel fabricators, and electronics technicians working with modular PCB stacking configurations will find this standoff a direct-fit solution for maintaining consistent board separation.

Key Features

• Male-female hex configuration allows stacking of multiple circuit boards at fixed height
• 2-56 unified thread on both ends for secure engagement with standard PCB hardware
• Hexagonal body profile at 3/16 inch across flats accepts standard nut drivers for installation
• Aluminum T3 material per QQ-A-225A Comp 2 standard — lightweight and dimensionally stable
• Bright uncoated finish with tight length tolerance of -0.005 to 0.005 inches
• Thread depth of 3/16 inch and thread length of 5/32 inch for consistent thread engagement

Compatibility

Designed as a standard 2-56 male-female hex standoff for use in PCB mounting, circuit board stacking, and control panel assembly applications where a 2-1/4 inch board separation is required.

Installation Notes

Installation is performed by electronics technicians, panel fabricators, or electricians assembling or servicing control boards. De-energize all equipment and discharge any capacitors before handling circuit boards or standoff hardware. Use a properly sized nut driver or hex socket matched to the 3/16 inch across-flats dimension to avoid deforming the soft aluminum hex body. Follow applicable enclosure and panel wiring standards, including NEC requirements, when installing standoffs inside electrical enclosures.
