Electro Hardware 1307M06F16256 Hex Standoff 2-56 5/16 in

Product Description

The ELECTRO HARDWARE 1307M06F16256 is a male-female hex circuit board standoff machined from aluminum alloy to T3 temper per QQ-A-225A Comp 2. It accepts a 2-56 thread on both the male and female ends and measures 5/16 inches (0.3125 inches) in overall body length with a 3/16-inch width across the hex flats. The bright, uncoated finish leaves the aluminum bare for applications where conductivity or minimal surface buildup matters. This type of standoff is installed by electronics assemblers, PCB technicians, and field service technicians who need to stack or elevate circuit boards within an enclosure at a fixed, precise spacing.

This standoff is used in control board assemblies, enclosure panel builds, and PCB stacking configurations across HVAC control systems, electrical panels, and other electronic equipment. The hex body allows a nut driver or wrench to seat the male post into a tapped hole while threading a mating fastener into the female end to secure a second board or component above. It is suited for light-duty, low-vibration indoor environments where aluminum hardware meets dimensional and material requirements.

Key Features

• 2-56 thread size on both male post and female receiver for standard PCB fastener compatibility
• Hex body profile at 3/16 inches across flats allows positive wrench engagement during installation
• 5/16-inch overall body length with a length tolerance of -0.005 to 0.005 inches for tight stacking clearances
• Aluminum T3 material per QQ-A-225A Comp 2 — lightweight and corrosion-resistant for indoor electronics use
• Bright, uncoated finish with no added plating or anodize layer
• Minimum order quantity of 10 units supports both service and production use

Compatibility

Designed as a standard 2-56 male-female hex standoff for use in circuit board assemblies and electronic enclosures requiring inch-series fastener hardware and aluminum construction per QQ-A-225A Comp 2.

Installation Notes

Installation is performed by electronics or controls technicians using a nut driver or open-end wrench sized to 3/16 inches across flats. Power down and de-energize all circuits in the enclosure before servicing any PCB mounting hardware. Avoid over-torquing the male post into the tapped board hole, as aluminum threads in small 2-56 sizes are susceptible to stripping. Follow applicable assembly drawings or OEM torque guidance for the specific control board being serviced.
