凸輪，半螺母

This replacement half nut fit perfectly on my lathe and the engagement was smooth right out of the box. Made a tricky alignment job much easier than I expected.

Installed this half nut on my 7x14 lathe and the engagement with the leadscrew is smooth right out of the box. The machining on the threads looks clean and precise, no filing needed to get it to slide into place.

I was relieved that the SKU 1374 designation made it dead simple to confirm I had the right replacement part. It engages the half nut mechanism smoothly with no binding, so my lathe is back to cutting accurate threads. A solid, no-fuss fix that saved me from buying a whole new assembly.
