Eva F. ★★★★★

I was tired of fumbling with Allen wrenches every time I needed to swap gears, and these thumb screws make the process effortless. The knurled grip is just deep enough to turn by hand, even with slightly greasy fingers. It’s a simple upgrade that saves real time on my mini lathe.

Ellie Q. ★★★★★

Finally, no more digging for an Allen wrench every time I swap gears. The knurled grip is just the right size for my fingers to get a solid turn. These two screws fit my mini lathe perfectly and make cover changes a breeze.

Finally, no more fumbling with an allen wrench to open the change gear cover. These knurled thumb screws grip perfectly and the threads matched my lathe without any issue. A simple upgrade that makes a daily task much more pleasant.
