Washer, Tab M16

The tab on this washer is exactly the right thickness to keep those lock nuts from creeping during heavy cuts, and it fit perfectly on my lathe's lead screw assembly. Takes the guesswork out of reassembly since it's keyed to the nut profile.

I was worried about the lock nuts vibrating loose during heavy use, but this M16 tab washer locks them down solid. It’s a simple, effective fix that took seconds to install.

These tab washers fit perfectly on my Sieg SC50, and the lock nuts haven't budged a bit after several hours of heavy use. The metal feels sturdy and the tabs engage the bearing lock nuts exactly as described.
