Once the torque limit is reached, the tool gives a loud ″click″ and will not turn the fastener any further, preventing over-tightening and damage to lightweight components. Includes 1/4″ drive bits in the four most common sizes for small bicycle fasteners, which are stored in the handle when not in use.

The ATD-1.2 features all-metal internal construction for years of accurate use, with a comfortable, ergonomic molded composite body. Each tool is assembled and calibrated at the Park Tool factory in St. Paul, Minnesota.

Torque range: 4, 4.5, 5, 5.5, or 6 Newton meters
