キャップスクリュー、M8x30、六角頭、全ねじ

Threading is clean and consistent all the way down, so it grabbed perfectly into my lathe's tool post with zero wobble. The hex head seated flush without stripping, and thirty millimeters was just right for the job.

Finally, a fully threaded M8x30 that actually fits my lathe tooling without any slop. The hex head sits flush in my wrench and the threads are clean enough to spin on by hand most of the way. This is the third pack I've ordered for the shop, and they've all been consistent.

Installing these on my lathe went smoothly and the fully threaded shaft held tight without any wobble. My only minor gripe is the hex socket could be a touch deeper for a better bite.
