Electro Hardware 1317M06F16256 Hex Standoff 2-56 5/8 in

Product Description

The ELECTRO HARDWARE 1317M06F16256 is a male-female hex circuit board standoff designed to create precise spacing between PCBs or between a PCB and a mounting surface. Machined from aluminum alloy T3, this standoff features a 2-56 thread on both the male and female ends and measures 0.625 inches in overall body length. The hex profile — 0.1875 inches (3/16 inch) across flats — allows for secure wrench engagement during installation. It meets the QQ-A-225A Comp 2 fastener standard and carries a bright, uncoated finish. Installed by electronics assemblers, field service technicians, and board-level repair professionals across industrial, commercial, and trade-equipment applications.

This standoff is suited for use in circuit board assemblies where controlled board-to-board or board-to-chassis spacing is required. The 2-56 thread size fits standard PCB mounting holes common in light-duty electronics enclosures, HVAC control boards, and similar low-voltage assemblies. The aluminum construction keeps weight low while providing adequate mechanical support in non-corrosive indoor environments.

Key Features

• Male-female hex standoff configuration allows stacking or chassis-mount installation
• 2-56 thread on both ends for compatibility with standard PCB mounting hardware
• 0.625 inch body length with a tight length tolerance of plus or minus 0.005 inches
• 3/16 inch (0.1875 inch) hex width across flats for wrench-driven installation
• Aluminum T3 material with bright, uncoated finish — lightweight and non-magnetic
• Meets QQ-A-225A Comp 2 fastener standard

Compatibility

Designed as a standard 2-56 male-female hex standoff for use in circuit board assemblies requiring inch-measurement fastener hardware and aluminum construction.

Installation Notes

Installation is typically performed by electronics technicians or field service personnel. Power down and de-energize all boards and associated circuits before handling or replacing standoffs. Use a hex driver or appropriately sized wrench sized for 3/16 inch across flats to avoid rounding the hex body. Do not overtighten — aluminum threads can strip under excessive torque, particularly in thin PCB mounting bosses.
