AC-032-2 - Floating Self-Clinching Nut by PennEngineering ® (PEM ® )

The PEM® AC-032-2 is a specialized Floating Self-Clinching Nut designed to provide high-strength, load-bearing threads while compensating for mating hole misalignment. Part of the AC™ Series, this fastener features an internal nut element that "floats" within a stationary outer retainer.

This floating action allows for a total adjustment of 0.76 mm (.030 in), effectively resolving assembly challenges where tolerances or minor drilling inaccuracies prevent standard fixed fasteners from aligning with mating components. The AC-032-2 is engineered with a Shank Code 2, making it suitable for slightly thicker host panels compared to the Shank Code 1 variant, ensuring a permanent, captive threading solution that remains secure under high torque or vibration.

Misalignment Compensation: The nut element can move up to 0.38 mm (.015 in) radially from the center, allowing for easier assembly of panels with multiple attachment points and reducing the need for extreme precision in hole placement.

Non-Locking Threads: Provides a standard free-running thread for applications where a self-locking feature is not required or preferred.

High Torque Resistance: The self-clinching retainer provides excellent resistance to rotation and push-out once properly installed in the host panel.

Permanent Attachment: Eliminates the risk of loose hardware falling into sensitive electronic assemblies during maintenance or operation.

Common Uses: Frequently used in telecommunications equipment, computer server enclosures, industrial controls, and automotive electronic modules.
