Overview
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.

Good questions
Get to know Park Tool
There's more to Park Tool than this one product. Our Park Tool page has the full Park Tool lineup we carry and more about the brand.
Visit the Park Tool page →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.
