Park Tool ATD-1.2 Adjustable Torque Driver for Cyclists

The Park Tool ATD-1.2 Adjustable Torque Driver is an essential tool for bicycle maintenance, adjustment, and assembly, particularly as carbon fiber components and low torque specifications become more prevalent. This shop-quality adjustable torque driver limits the torque applied to bolts and fasteners, preventing over-tightening and damage to lightweight components.

The torque setting of the ATD-1.2 is adjustable by hand to 4, 4.5, 5, 5.5, or 6 Newton meters (Nm). Once the predetermined torque limit is reached, the tool emits a loud "click" and will not turn the fastener any further, ensuring precise control. Included with the driver are four of the most common 1/4" drive bits (3mm, 4mm, 5mm, and T25) for small bicycle fasteners, stored conveniently within the handle for easy access.

Featuring all-metal internal construction, the ATD-1.2 is built to last and deliver accurate performance for years to come. The comfortable, ergonomic composite molded grip provides a secure and fatigue-reducing hold during use. Each tool is assembled and calibrated at Park Tool's factory in Minnesota, ensuring the highest quality control.

In addition to the adjustable ATD-1.2, Park Tool offers a line of preset torque drivers for specific torque values: the PTD-4 (4Nm), PTD-5 (5Nm), and PTD-6 (6Nm). For a broader range of torque applications, the TW-5.2 and TW-6.2 Ratcheting Click-Type Torque Wrenches cover 2 to 14 Nm and 10 to 60 Nm, respectively.

Since its origins in the back of a bike shop in 1963, Park Tool has been dedicated to designing and manufacturing high-quality tools that empower mechanics and riders of all skill levels to service their bicycles. The company's torque wrenches are a product of their decades of experience and expertise in the industry, ensuring reliable performance in the shop and on the trail.

Whether you're working on lightweight carbon fiber components or performing routine maintenance, the Park Tool ATD-1.2 Adjustable Torque Driver and the company's other precision torque tools are invaluable for ensuring the safe and proper assembly of your bicycle.
