4 3/4" Long 16 TPI Threaded Doorknob Swivel Spindle With 3/8" Solid Centers

This sturdy spindle is designed to facilitate new or vintage doorknobs with two 3/8-inch solid centers for use with privacy latches and mortise locks with larger hubs. Its hardened steel construction provides smooth operation and long-lasting wear. At 4 3/4-inch in length, it's ideal for thicker doors.

Dimensions: 4 3/4" long by 9/32" thick and has 16 threads per inch with 3/8" solid centers.

If you need a threaded spindle you need to know what the threads per inch are and check to see that the spindle thickness is small enough to fit through the hub of your lock or latch.
