Park Tool ATD-1.2 Adjustable Torque Driver – 4 to 6 Nm With carbon fiber components and low torque specifications becoming more common on bicycle components, a torque driver is an essential tool for bike maintenance, adjustment and assembly. The Park Tool ATD-1.2 is a shop-quality adjustable torque driver that limits torque applied to bolts and fasteners. The torque setting of the ATD-1.2 is adjustable by hand to either 4, 4.5, 5, 5.5, or 6 Newton meters (Nm). 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 4 most common sizes for small bicycle fasteners (3mm, 4mm, 5mm and T25), 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 composite molded grip. Each tool is assembled and calibrated at our factory in Minnesota.
