HAZET – Das Werkzeug logo

HAZET has stood for quality and innovation since its beginnings in 1868. Over the past 155 years, we have continuously expanded and improved our portfolio. Starting with wrenches and screwdrivers, our product range now also includes a wide range of open-end wrenches and nut-drivers, high-precision torque wrenches, ratchets, tool trolleys and customised specialty tools. HAZET has established itself over the years as an internationally recognised quality brand. In close co-operation with renowned car manufacturers and motorsport teams, we continue to develop special tools for the automotive industry to this day. But sectors such as industry, aerospace and two-wheelers also rely on our expertise.
