Park Tool ADJUSTABLE TORQUE DRIVER 4, 4.5, 5, 5.5, 6Nm AWS-9.2

Protect your bike’s most critical components with the Park Tool ATD 1.2 Adjustable Torque Driver—a compact, workshop-quality tool designed for accurate, repeatable tightening. As modern bikes increasingly rely on lightweight aluminium and carbon parts, precise torque application is essential to avoid damage and ensure optimal performance.

The ATD 1.2 allows you to easily set your desired torque within the key 4–6Nm range, covering the majority of cockpit and component bolts. Once the selected torque is reached, the internal mechanism delivers a clear “click” and prevents further tightening, eliminating the risk of over-torquing delicate components.

Built with all-metal internals and an ergonomic composite handle, this tool is engineered for durability and comfort, whether you're working in a home garage or a professional workshop. Compact, reliable, and easy to use, it’s an essential addition to any serious cyclist’s toolkit.

Key Features

• Adjustable torque settings: 4, 4.5, 5, 5.5, 6 Nm
• Audible click and slip mechanism prevents over-tightening
• Includes common bits: 3mm, 4mm, 5mm hex and T25 Torx
• 1/4" hex drive with integrated bit storage
• All-metal internal construction for long-term accuracy
• Ergonomic handle for control and comfort

Why You Need a Torque Driver

With modern bikes—especially those featuring carbon components—tightening bolts “by feel” is no longer reliable. A torque driver ensures:

• Correct clamping force on stems, seatposts, and handlebars
• Protection against thread damage and component failure
• Consistent, repeatable adjustments

The ATD 1.2 is widely regarded as one of the best compact torque tools available, offering a balance of simplicity, reliability, and portability.
