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 PTD-4 is a shop-quality torque driver preset to apply 4 Newton meters of torque to bolts and fasteners. 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 PTD-4 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.
