Steel swivel spindle for door locks

The Progressive Hardware 45HD-20-TP is a new steel swivel spindle measuring 3/8 inch square by 5 inches long. It features 1/2-20 TPI threading with tapped holes on both sides and a satin chrome finish. The spindle is sold as a single boxed unit keyed different.

Suits repairs on compatible knob sets

This spindle serves as a direct replacement for the Progressive #2638 brass knob set. It is not intended for installations that require a different square dimension, a non-threaded spindle or a shorter overall length. Buyers needing a solid spindle or a different thread pitch should select another part.

3/8 inch square by 5 inch steel shaft

The defining specification is the 3/8 inch square cross-section combined with a 5 inch overall length in steel. This size and material determine whether the spindle fits the existing lock mechanism and withstands daily operation. Verify both measurements against the hardware being repaired before purchase.
