進給螺桿，Y軸16 TPI加長型

Installed this as a direct replacement and the 16 TPI threading matched perfectly, table movement is smooth and consistent. Took maybe ten minutes to swap out the old one and adjust the zero stop. Really happy with how precise the adjustments feel now for front-to-back positioning.

Was a bit nervous swapping out the stock screw on my mill, but this one dropped right in and the table movement feels noticeably smoother. The 0.0625" per turn is spot-on for my dial readings, and it’s held up through a few solid machining sessions without any backlash surprises.

The threads are cut clean and the 16 TPI pitch matches perfectly on my mill, so the table movement is consistent with zero binding along the full travel. I replaced a worn screw and the front-to-back motion feels noticeably smoother now.
