Electro Hardware P285M12F21256 Hex Standoff 2-56 1/8 in

Product Description

The ELECTRO HARDWARE P285M12F21256 is a female hex circuit board standoff designed for securing printed circuit boards to chassis, enclosures, and mounting surfaces in electronic assemblies. This standoff accepts a 2-56 threaded fastener and features fully threaded engagement through its 1/8-inch thread depth. The hex body profile measures 3/16 inches across flats, allowing installation and removal with a standard hex wrench or nutdriver. Constructed from steel with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-S-633 standards, it provides corrosion resistance suitable for indoor electronic equipment environments. Electronics assemblers, HVAC control board technicians, and electrical panel builders install this type of standoff during board mounting and rework operations.

This standoff is suited for use in residential and light commercial electronic control assemblies, including HVAC control boards, motor drives, relay panels, and general PCB mounting applications. The 2-56 thread size is common in compact electronic enclosures where space is limited and precise board-to-chassis spacing is required. The 1/8-inch overall length positions the board close to the mounting surface, making it appropriate for low-profile installations. Its inch-system dimensions and standard thread specification make it a straightforward replacement or replenishment component for electronics maintenance and assembly operations.

Key Features

• Female 2-56 thread accepts standard 2-56 machine screws for secure board fastening
• Fully threaded interior with 1/8-inch thread depth for maximum thread engagement in a compact body
• Hex body shape with 3/16-inch width across flats for wrench-driven installation
• Steel construction with clear zinc chromate finish per ASTM B633 Type 1 and QQ-S-633
• 1/8-inch overall length suits low-profile PCB standoff applications
• Inch-system fastener compatible with standard US-spec electronic hardware

Compatibility

Designed as an OEM-style replacement or standard-production component for PCB mounting applications requiring a 2-56 female hex standoff with 1/8-inch overall length in inch-system electronic assemblies.

Installation Notes

Installation is typically performed by electronics assemblers, HVAC technicians, or electricians during control board mounting or field rework. Power down and de-energize all equipment before servicing any control board or electronic assembly. Use an appropriately sized hex wrench or nutdriver sized for 3/16-inch across-flats to avoid stripping the hex body. Do not over-torque; standoffs in PCB assemblies are generally installed to snug contact without exceeding the torque capacity of the 2-56 thread.
