Electro Hardware 1310M06F16440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1310M06F16440 is a male-female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from aluminum alloy T3 to the QQ-A-225A Comp 2 fastener standard, this standoff features a bright, uncoated finish and a hex body shape that allows installation and removal with standard hex tooling. The overall body length is 0.4063 inches, the width across flats is 0.1875 inches, and the thread size is 4-40. The male end provides a stud for stacking into a receiving female thread, while the female end accepts the next fastener in a board stack.

This standoff is used in electronics assembly and rework applications where circuit boards must be mounted at a fixed, repeatable height above a chassis or a second board. Typical install scenarios include control board assemblies in HVAC equipment, industrial control panels, and embedded system enclosures. The inch-series 4-40 thread size is among the most common in North American PCB hardware, making this standoff a straightforward fit in a wide range of light-duty board-mounting applications. Installation is performed by electronics technicians and field service professionals working on control board assemblies.

Key Features

• Male-female hex configuration allows stacking of multiple boards with consistent spacing
• 4-40 inch-series thread on both ends suits the most common North American PCB fastener pattern
• Aluminum T3 material provides a lightweight, non-magnetic fastener body
• Bright uncoated finish meets QQ-A-225A Comp 2 fastener standard
• Hex body shape accepts standard nut drivers and hex keys for tool-driven installation
• Thread depth of 0.25 inches provides reliable thread engagement in typical board-mount applications

Compatibility

Designed as an OEM-style replacement or new-install standoff for circuit board assemblies using 4-40 inch-series fasteners in electronic control panel and PCB mounting applications.

Installation Notes

Installation is typically performed by electronics technicians or control board service professionals. De-energize all circuits and discharge any stored capacitance before handling circuit boards or board-mounted hardware. Use an appropriately sized hex driver or nut driver to seat the standoff without over-torquing the aluminum threads. Inspect existing female mounting points for thread damage before installing new standoffs.
