John X. ★★★★★

Needed a replacement for my SC4 lathe cross-slide and this key was a perfect match for the factory slot. Fit snugly without any filing, just like the original part.

Edward ★★★★★

The 6x25 mm flat key dropped right into my SC4 lathe's shaft slot without any filing needed. It's clearly the correct part #168 replacement for that intermediate gear train.

Timothy ★★★★★

Finally, a replacement key that actually fits the SC4's intermediate shaft without any filing. The 6x25 mm dimensions are dead-on accurate, so it slid right into place on my lathe.
