Electro Hardware P325M03F21256 Hex Standoff 2-56 3/4in

Product Description

The ELECTRO HARDWARE P325M03F21256 is a female hex circuit board standoff designed to create measured separation between printed circuit boards and mounting surfaces. Machined from brass with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff accepts a 2-56 threaded fastener and provides a female-threaded interior for stacking or securing mating hardware. The hexagonal body measures 3/16 inches across flats, making it compatible with standard hex drivers and wrenches. Overall length is 3/4 inches with a thread depth of 3/16 inches. Electronics technicians, PCB assemblers, and electrical panel builders commonly install these in control boards, enclosures, and rack-mount equipment.

This standoff is suited for light-duty electronic assembly applications where secure, repeatable board-to-chassis or board-to-board spacing is required. Typical installations include residential and commercial HVAC control boards, industrial control panels, power supply assemblies, and general PCB mounting scenarios. The inch-measurement system and 2-56 thread size are standard in North American electronics assembly. The zinc-chromate finish provides corrosion resistance appropriate for indoor electrical enclosure environments.

Key Features

• Female hex body accepts 2-56 threaded fasteners for secure PCB mounting
• Brass construction with clear zinc chromate finish for corrosion resistance
• Meets ASTM B633 Type 1 and QQ-B-626 Comp 22 fastener standards
• 3/4 inches overall length with 3/16 inches thread depth
• Hexagonal body profile allows installation with standard hex drivers or open-end wrenches
• Length tolerance held to plus or minus 0.005 inches for consistent stack height

Compatibility

Designed as an OEM-style replacement or new-installation component for circuit board assemblies requiring inch-series 2-56 female hex standoffs in residential, commercial, or industrial electronic enclosures.

Installation Notes

Installation is performed by electronics technicians or licensed electricians working on control boards and enclosures. De-energize all circuits and discharge any capacitors before handling PCB hardware. Use a properly sized hex driver or open-end wrench matched to the 3/16-inch across-flats dimension to avoid rounding the hex body. Do not over-torque — brass threads can strip or shear if excessive force is applied.
