Electro Hardware P625M12F21-832 Female Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE P625M12F21-832 is a female hex circuit board standoff designed to create a fixed, threaded spacing point between a PCB and a mounting surface or between stacked boards. It features an 8-32 female thread, a 2-inch overall length, and a 1/4-inch hex width across flats, allowing standard hex drivers to seat it securely. Constructed from Grade 2 steel with a zinc-plated clear chromate finish meeting ASTM B633 Type 1 and QQ-S-633 standards, it provides corrosion resistance suitable for indoor electronic assemblies. Electronics assemblers, panel builders, and field technicians working on control boards and enclosures are the primary installers.

This standoff is used in residential and commercial electronic assemblies wherever a circuit board must be raised and isolated from a metal chassis or mounting plate. Typical applications include HVAC control board mounting, electrical enclosure PCB support, and industrial panel assembly. The hex body shape and female threading allow clean, tool-assisted installation in confined panel spaces where hand-tightening is not practical.

Key Features

• Female 8-32 thread accepts machine screws for positive board retention
• 2-inch overall length provides fixed board standoff height for standard panel depths
• Hex body shape (1/4 inch across flats) enables torque application with standard nut drivers or hex wrenches
• Grade 2 steel construction delivers reliable mechanical strength for repeated assembly cycles
• Zinc-plated clear chromate finish meets ASTM B633 Type 1 and QQ-S-633 corrosion resistance standards
• Inch measurement system with a tight length tolerance of -0.005 to 0.005 inches for consistent stack height

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board mounting applications requiring an 8-32 female thread and a 2-inch standoff height in hex-body inch-series hardware.

Installation Notes

Installation should be performed by a qualified electronics assembler or technician. Always de-energize the control panel or PCB assembly and discharge any stored capacitance before handling circuit boards or fasteners. Use a properly sized hex driver or nut driver matching the 1/4-inch across-flats dimension to avoid rounding the hex body. Do not over-torque; apply only enough torque to seat the standoff firmly against the mounting surface without deforming the board or chassis material.
