Electro Hardware P373M06F16256 Hex Standoff 2-56 Aluminum

Product Description

The ELECTRO HARDWARE P373M06F16256 is a female hex circuit board standoff designed to create measured separation between PCBs, enclosure panels, and mounting surfaces in electronic assemblies. Machined from aluminum alloy to the QQ-A-225A Comp 2 fastener standard, this standoff accepts a 2-56 thread and delivers a 1.5-inch overall length with a 0.1875-inch (3/16 inch) width across flats. The plain, bright uncoated finish keeps the aluminum surface free of additional treatment. Licensed electrical technicians, electronics assembly technicians, and panel builders use these standoffs when stacking boards or securing control assemblies in HVAC, industrial, and commercial electrical enclosures.

This standoff is suited for light-duty circuit board mounting applications where compact thread sizing and precise height control are required. The 2-56 thread is common in small electronics assemblies, instrument panels, and control board housings found in residential and commercial HVAC equipment, electrical control panels, and similar low-voltage enclosures. The hex body shape allows installation and removal with standard hex drivers or nut drivers, making it practical in confined board-level spaces.

Key Features

• Female 2-56 threaded bore accepts standard 2-56 machine screws for secure board-to-standoff fastening
• 1.5-inch overall length provides consistent PCB-to-surface clearance in layered assemblies
• 3/16-inch (0.1875-inch) width across flats sized for standard hex drivers
• 3/16-inch thread depth on female end ensures adequate thread engagement for small fasteners
• Aluminum construction per QQ-A-225A Comp 2, Grade T3 — lightweight and corrosion resistant
• Plain bright finish with no coating keeps dimensional tolerances tight and surfaces unaltered

Compatibility

Designed as an OEM-style replacement or standard-service standoff for applications requiring 2-56 female hex circuit board standoffs with a 1.5-inch overall length in inch-system assemblies.

Installation Notes

Installation is typically performed by electronics assembly technicians or licensed electricians working on control board assemblies. De-energize all circuits and discharge any capacitors before handling or replacing circuit board hardware. Use a correctly sized hex driver or nut driver matched to the 3/16-inch flats to avoid deforming the aluminum hex body. Follow applicable NEC or equipment manufacturer guidelines for control board mounting and enclosure reassembly.
