What is the Park Tool SD-3 Flat-Head Screwdriver 3mm for?

The Park Tool SD-3 Flat-Head Screwdriver is a 3mm precision flat-blade tool sized for the smallest slotted fasteners found on bicycle components: cable pinch bolts, brake pad adjustment screws, and other fine-thread hardware where a standard screwdriver is simply too wide to seat properly. The chrome vanadium steel tip is ground to a precise 3mm width to prevent cam-out and protect the soft alloy fasteners common to high-end components.

The ergonomic handle allows controlled, tactile torque application, which is critical when working with tiny fasteners that strip at surprisingly low force. Keep the SD-3 alongside your Phillips screwdrivers as a complete set. Having the right blade width for each job is one of the simplest ways to avoid unnecessary fastener damage during service work.

FAQ

What fasteners is the SD-3 designed for?

The SD-3 is sized for 3mm flat-head slotted fasteners found on cable pinch bolts, small brake hardware, and accessory mounting screws throughout the bike.

How is the SD-3 different from the SD-6?

The SD-3 has a narrower 3mm tip compared to the SD-6's 6mm tip. Use the SD-3 for smaller fasteners where the SD-6 would be too wide to seat properly in the slot.

Is the tip on the SD-3 replaceable?

No. The SD-3 is a fixed one-piece design with a chrome vanadium shaft intended for long-term professional use.
