Park Tool Preset Torque Driver

Standard hex keys rely on feel, which often leads to over-tightening and damaging lightweight components like carbon fiber handlebars or seatposts. A preset torque driver automatically limits the force applied, ensuring you hit the exact manufacturer-recommended torque every time.

No, this specific model is factory-preset to 5Nm and cannot be adjusted. It is designed to be a dedicated, reliable tool for the most common torque setting found on modern bicycles.

Yes, the tool functions like a standard driver for loosening bolts. The torque-limiting mechanism only engages when tightening in a clockwise direction.

The driver comes with 3mm, 4mm, 5mm, and T25 bits, which cover the vast majority of bicycle maintenance tasks. It uses a standard 1/4-inch hex drive, so you can swap in any compatible bit from your existing collection.

When you reach the 5Nm limit, the tool will produce a distinct 'click' or slip sensation, signaling that you should stop turning. This tactile feedback is your confirmation that the bolt is secure without being over-tightened.

Absolutely. It features an all-metal internal construction designed for longevity, making it robust enough for both professional mechanics and home enthusiasts who want a tool that will last for years.
