I have bought a bits set and there is this bit: a bit with a groove

It is a Y shaped bit, and there is a groove on the inside of the branches. The angle is approximatively 90˚ (a little more).

It's a bit for screwing in eye bolts, or hooks.

eyebolt open loop or hook screw

  • Attach the bit to your driver handle or power driver.
  • Fit the eye bolt into the groove.
  • Screw the bolt in/out, without hurting your fingers.

The list of bits in this set, lists it as a "Y-shape hook driver".

Also can be used for wing nuts.
