Overview

What sets the Park Tool SD-0 apart for bike work?

The Park Tool SD-0 is a #0 Phillips screwdriver purpose-built for the small, precision fasteners found throughout bicycle drivetrain and brake systems. Machined from chrome vanadium steel, the tip is precision-ground to engage #0 Phillips heads fully, eliminating cam-out and protecting soft alloy screws during adjustment and assembly work.

The contoured handle delivers comfortable grip and controlled torque, making it ideal for fine-tuned work like dialing in derailleur limit screws or securing brake hardware. This is the screwdriver you reach for when tip fit and feel matter more than raw force.
