Item # PTD-4(discontinued) / Tools / Torque Tools
Preset Torque Driver — 4 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 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.
- Torque range: preset to 4 Newton meters
- Included bits: 3mm hex, 4mm hex, 5mm hex, T25 Torx®-compatible
