Replacement Steel Spindle for Vintage Knobs

This two-piece sectional spindle replaces worn originals on Corbin Russwin, Yale, Marks, Norwalk, National, Baldwin and Progressive hardware. The 9/32" square steel shaft measures 2-5/8" long and uses 3/8"-20 threads. It fits mortise locks that accept a split spindle design.

Satin Chrome Finish With Keyed Different Packaging

The satin chrome coating resists corrosion on the exposed ends. Each box contains a single spindle keyed differently, so multiple doors can operate independently. No additional screws, escutcheons or installation tools are included in the package.

Thread Standard Limits Compatibility To 3/8"-20

The 3/8"-20 thread pitch only engages lock bodies cut to that exact specification. Doors with metric threads, coarser Unified threads or solid one-piece spindles cannot use this part. Verify the lock body threading before ordering.

Questions about this item

Will the 3/8"-20 threaded sections need periodic lubrication?

The steel threads on this two-piece sectional spindle do not require scheduled lubrication under normal residential use.

What fails first if the 9/32" square steel spindle is over-torqued daily?

The 3/8"-20 threads on the sectional halves will strip before the 9/32" square shaft yields.

Does the satin-chrome finish affect heat buildup during continuous lever operation?

The thin satin-chrome coating adds no measurable thermal resistance; the steel body dissipates hand-generated heat instantly.
