Park Tool SD-3 Flat-Head Screwdriver - 3mm
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 — 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.
