Park Tool Preset Torque Driver 3-4-5-T25 4 Nm Skiftnyckel

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 PTD-4 is a shop-quality torque driver that limits torque applied to bolts and fasteners. Once the preset torque limit of four Newton meters (Nm) 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 PTD-4 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.
