Electro Hardware P561M12F21-632 Female Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE P561M12F21-632 is a female hex circuit board standoff designed to create a fixed, threaded mount point between a printed circuit board and a chassis or secondary board. Machined from Grade 2 steel with a zinc-plated clear chromate finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff delivers corrosion resistance suitable for electronic enclosures and control panel assemblies. It features a 6-32 female thread, a 1-inch overall length, and a 1/4-inch hex body width across flats for positive wrench engagement. Electronics assemblers and control panel technicians install these to stack boards at a consistent, secure spacing.

This standoff is used in residential and commercial electronic assemblies wherever a 6-32 threaded female mount point is required to space a circuit board off a mounting surface. Typical applications include HVAC control boards, industrial enclosures, electrical panel assemblies, and general PCB mounting configurations. The hex body allows installation with a standard open-end or socket wrench, making it suitable for production and field service work alike.

Key Features

• 6-32 female thread for direct engagement with machine screws or male standoffs
• 1 inch overall length with a tight length tolerance of -0.005 to +0.005 inches
• 1/4 inch hex width across flats for wrench-driven installation
• Grade 2 steel construction for reliable mechanical strength in panel assemblies
• Zinc-plated clear chromate finish meets ASTM B633 Type 1 and QQ-S-633
• Hex body shape provides positive anti-rotation during assembly

Compatibility

Designed as a standard female hex PCB standoff for use in any assembly requiring a 6-32 threaded female mount point with a 1-inch stack height and 1/4-inch hex body.

Installation Notes

Installation is performed by electronics assemblers or control panel technicians using an open-end wrench or hex socket sized to 1/4 inch across flats. Always de-energize and discharge any board or enclosure before installing or removing standoffs. Avoid over-torquing, as this can strip the 6-32 thread or crack the mounting hole in the PCB. Follow applicable assembly drawings and workmanship standards for torque and thread engagement requirements.
