Electro Hardware 1393M06F16256 Hex Standoff 2-56 3in

Product Description

The ELECTRO HARDWARE 1393M06F16256 is a male-female hex circuit board standoff machined from aluminum alloy and used to create precise spacing between stacked PCBs or between a circuit board and an enclosure panel. The standoff features a 2-56 unified thread on both the male and female ends, a 3-inch overall body length, and a 3/16-inch hex width across flats. The uncoated bright finish meets QQ-A-225A Comp 2 material standards, confirming alloy and dimensional traceability. Electronics assembly technicians and electrical contractors install these during board-level assembly and enclosure builds.

This standoff is suited for light-duty circuit board mounting applications where a 2-56 thread pitch and 3-inch separation distance are required. Typical use cases include rack-mounted electronics, control enclosures, and industrial PCB assemblies where aluminum is preferred for its light weight and corrosion resistance. The hex body allows wrench engagement during installation, reducing the risk of cross-threading or overtightening on delicate board-level hardware.

Key Features

• Male-female thread configuration allows stacking of multiple standoffs or direct board-to-board mounting
• 2-56 unified thread size on both ends for compatibility with standard 2-56 machine screws and inserts
• 3-inch overall body length with a length tolerance of -0.005 to 0.005 inches for precise PCB spacing
• 3/16-inch hex width across flats permits standard hex driver or wrench installation
• 5/32-inch thread length on the male end
• Aluminum T3 grade material, bright and uncoated, meeting QQ-A-225A Comp 2 fastener standard

Compatibility

Designed as an OEM-style replacement or direct-install standoff for circuit board assemblies requiring a 2-56 thread and 3-inch separation distance in aluminum construction.

Installation Notes

Installation is typically performed by electronics assembly technicians or licensed electricians during enclosure and PCB build-out. Power down and de-energize all circuits before installing or removing standoffs in live control panels. Use a properly sized hex driver or wrench on the 3/16-inch flats to seat the standoff without stripping the thread. Follow applicable NEC guidelines when mounting control boards inside electrical enclosures.
