Standard 5/16" universal spindle with both threads (20TPI) and drilled for set screws (10-24), measuring 4" in length. This spindle has 20 threads per inch and will facilitate both vintage glass, brass and porcelain door knobs.
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. Learn about hardware >
