The Park Tool SD-0 Phillips Screwdriver is built around a #0 Phillips tip — the right size for the small fasteners found on cycling computers, handlebar-mounted accessories, and hydraulic brake reservoir caps. Park Tool constructs this screwdriver for workshop use, with a durable build and an ergonomic handle designed to give you comfortable grip and reliable torque on delicate, smaller screws where control matters most. It's a straightforward tool, but having the correct tip size is what separates clean work from stripped heads. The #0 Phillips is a size that often gets overlooked in general-purpose screwdriver sets, yet it comes up regularly on modern cycling components.
