Park Tool ATD-1.2 - Adjustable Torque Driver Tool, Blue

Brand: Park Tool

Availability set by the retailer

The Park Tool ATD-1.2 is a shop-quality adjustable torque driver that limits the torque applied to fasteners, preventing overtightening and damage to lightweight components. Designed for precision work on bicycles, electronics, and other delicate assemblies where exact torque specification is critical, this torque driver adjusts to apply 4, 4.5, 5, 5.5, or 6 Newton Meter (Nm) of torque when rotating clockwise. Once the preset torque is reached, the internal mechanism slips, audibly and tactilely signaling that the correct torque has been achieved — eliminating the guesswork and protecting carbon fiber, aluminum, and other sensitive materials from over-tightening damage. The ATD-1.2 features all-metal internal construction for long life and consistent, repeatable performance in professional shop environments. The blue, ergonomic handle provides a comfortable, secure grip for precise control, and the clearly marked torque scale makes it easy to select the desired setting at a glance. A favorite among bicycle mechanics and professional technicians who work with sensitive, torque-sensitive components, the ATD-1.2 is an essential tool for anyone assembling or maintaining high-performance equipment where over-tightening could cause costly damage.

Choosing Drivers

How do I choose a screwdriver?

Match the tip to the fastener recess exactly, choose a handle that fills your hand for torque, and pick a shank length that reaches the fastener without bottoming out. For electrical work, insulated handles rated to a recognized standard add a safety margin. A set covering common tip types covers most jobs.
