In order to avoid rotation during installation, D nuts are specialised fasteners with a single flat side. They are ideal for situations where anti-rotation is crucial because of their special design, which increases stability and guarantees that the nut stays aligned.

The distinctive exterior thread of the D Nuts for Wood ensures secure locking and provides excellent resistance to pull-out caused by tensile, vibration, or torsion loads. The flange's head keeps covered surfaces from separating, and the D nut is driven too far.

In some situations, such as sheet applications, when a tapped or drilled thread cannot be utilised for structural reasons, D nuts are ideal. These nuts also withstand extremes of temperature, making them incredibly resilient.
