Stanley Proto has introduced a new line of ratcheting wrenches with spline box ends, in Metric and English versions. The new tools are part of a 95-SKU line extension, and include double-end box wrenches and combination wrenches. All have a ratcheting spline box head that lets users apply or remove fasteners without having to continually remove and re-attach the wrench. The combination wrench has an open end featuring the Stanley® Proto® patented Anti-Slip Design (ASD).
