Hazet was founded in Remscheid, Germany in 1868 by Hermann Zever. Ha-Zet came from a shorting of his first and last name. The company has continued to grow in the last 150 years but still maintains its family ties with the 4th and 5th generation (Hermann Jochen Zerver and Matthias J. Hoffmann, respectively) of Herman Zerver still running the company.

Hazet offers a complete range of hand tools, especially for the automotive, industrial, and aerospace sectors. Products include screwdrivers, wrenches, torque products, screwdriver bits, pliers, and a plethora of specialty tools. Hazet manufacturers many tools for specific automotive brands such as Mercedes-Benz, BMW, Volkswagen, Audi, Porsche, and MAN Truck & Bus.

Hazet Tools come with a lifetime warranty (except for bits and adapters) against material defects and faulty workmanship.
