With the Tormek EzyLock, which is both a nut and a washer, you need no tools for mounting and dismounting the stone. The special pitch on the left hand thread causes the rotation of the wheel to tighten the nut to the right torque.

Turn the Ezylock anticlockwise by hand and the grindstone will automatically tighten during the first sharpening.

When dismounting, you turn the stone clockwise and the EzyLock will automatically become loose.

This construction also makes it very easy to work with different grindstones (Tormek Original Grindstone
SG-200 and Japanese Waterstone SJ-200).

Including stainless steel main shaft, EzyLock composite nut, stainless steel washer and nylon bearings. Fits Tormek T-3, Tormek 1200 and all older models with 200 mm (8") stone.
