Benjamin ★★★★★

The SC4-10 part number matched perfectly with my lathe diagram, and it threads on smoothly without any wobble. This little nut got my tailstock locking tight again after the old one stripped out.

Sebastian I. ★★★★★

The SC4-10 part number on the diagram matched my bench lathe perfectly, no guesswork needed. Solid steel construction and the threads engaged smoothly, so the tailstock locks down tight now without any wobble.

Benjamin ★★★★★

Finally, a locking nut that actually fits the SC4 tailstock without any filing or shimming needed. The threads engaged perfectly from the first turn, and the knurling gives a great grip even with oily hands.
