Electro Hardware P469M12F21256 Female Hex Standoff 2-56

Product Description

The ELECTRO HARDWARE P469M12F21256 is a female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic enclosures and control panels. This standoff features a 2-56 female thread, a 3-inch overall length, and a 3/16-inch hex body width across flats. Constructed from steel with a clear zinc chromate finish applied to ASTM B633 Type 1 and QQ-S-633 standards, it provides corrosion resistance suitable for industrial and commercial control board assemblies. Installation is performed by electronics technicians, electricians, and HVAC controls specialists working on panel fabrication or board-level serviceability.

This standoff is suited for use in residential and commercial electronic control assemblies, including HVAC control boards, instrumentation enclosures, and custom panel builds where a secure, threaded female mount is required. The 3-inch OAL provides generous clearance between stacked boards or between a board and a chassis surface. The hex body allows for tightening and loosening with standard hex tools without slipping. Sold individually, it is appropriate for prototype builds, service replacement, and low-volume panel assembly work.

Key Features

• Female 2-56 thread accepts a mating male 2-56 fastener on both ends
• 3-inch overall length provides substantial board-to-surface standoff clearance
• 3/16-inch hex body width across flats allows wrench or socket tightening
• Steel construction with clear zinc chromate finish per ASTM B633 Type 1 and QQ-S-633
• 3/16-inch thread depth on each end for secure fastener engagement
• Length tolerance held to plus or minus 0.005 inches for consistent stacking

Compatibility

Designed as a standard female hex circuit board standoff for any application requiring a 2-56 threaded mount with a 3-inch overall length and 3/16-inch hex body in an inch-measurement fastener system.

Installation Notes

Installation is performed by electronics technicians or electricians assembling or servicing control panels and circuit board assemblies. Always power down and de-energize the enclosure before handling any circuit board hardware. Use an appropriately sized hex wrench or socket to torque the standoff body without contacting board traces or components. Verify mating fastener thread class is compatible with the 2-56 female thread before assembly to avoid cross-threading or stripping.
