Customer Reviews (4.6 / 5 · 5 reviews)

Sophia ★★★★★

Fits perfectly on my SC4 lead screw assembly—threads engaged smoothly without any binding. Glad I found this genuine replacement part #68, feels solid and well-machined.

Mia ★★★★★

Installed this M16x1.5 lock nut on my SC4 lead screw assembly and it seated perfectly against the bearing, just like the original part #68. The threads are precise and the nut holds tight without any play.

Penelope ★★★★★

Threads went on clean with no cross-threading, which was my main worry ordering a replacement. It's a proper M16x1.5 bearing lock nut and sits flush on the lead screw assembly just like the original part #68 did. Lathe's back to running true with zero play in the bearing.
