Counterweight Shaft Safety Knob (SCWTKB)

The threading was a perfect match for my older shaft setup, and the safety washer sits flush without any wobble. Feels solid and well-machined, exactly what I needed for a secure fit.

I needed a knob that would fit my older counterweight shaft securely, and the 5/16"-18 thread on this one threaded on perfectly with no wobble. Using it with the proper safety washer gives real peace of mind. Exactly the right part for the job.

The threads on this knob are cut clean and it screws on smoothly without any wobble. I paired it with the safety washer and it locks down my counterweight shaft securely.
