Electro Hardware P625M06F16-440 Hex Standoff 2in 4-40

Product Description

The ELECTRO HARDWARE P625M06F16-440 is a female hex circuit board standoff designed to create fixed spacing between printed circuit boards and mounting surfaces. Machined from aluminum alloy to material grade T-3 and finished with an anodized bright coating, this standoff provides corrosion resistance and a clean surface for stacking or securing PCBs in electronic enclosures and panel assemblies. The hex body measures 0.25 inches across flats and an overall length of 2 inches, with a 4-40 female thread on one or both ends. It is installed by electronics assembly technicians, panel builders, and field service personnel working on control boards in HVAC, electrical, and industrial equipment.

This standoff is suited for residential and commercial control panel assemblies where PCBs require rigid, measured separation from a chassis or mounting plate. The 4-40 thread size is a standard fastener size commonly used in light-duty electronic and control board applications. The anodized aluminum construction keeps weight low while offering adequate mechanical strength for typical board-mounting loads. The 2-inch overall length makes it appropriate for assemblies that require greater board clearance than standard short standoffs provide.

Key Features

• Female hex body accepts 4-40 threaded fasteners for secure PCB mounting
• 2-inch overall length provides generous board-to-chassis clearance
• Aluminum construction with anodized bright finish for corrosion resistance
• Hex body shape at 0.25 inches across flats allows standard wrench or nut-driver installation
• Meets QQ-A-225A Comp 2 fastener standard
• Length tolerance held to plus or minus 0.005 inches for precise stacking

Compatibility

Designed as an OEM-style replacement or new-installation standoff for control boards and PCB assemblies that use standard 4-40 threaded hardware in inch-measurement systems.

Installation Notes

Installation should be performed by qualified electronics assembly or field service technicians. De-energize all circuits and discharge any stored energy in the assembly before handling circuit boards or standoffs. Use an appropriately sized nut driver or hex wrench on the 0.25-inch flats to avoid deforming the aluminum body - do not over-torque. Follow applicable NEC guidelines when installing control boards inside electrical enclosures.
