What Hermann Zerver does

HAZET-WERK Hermann Zerver GmbH & Co. KG is a privately held, family-owned German professional tool manufacturer founded in 1868 and headquartered in Remscheid, with a second manufacturing facility (Werk 2) in Heinsberg. The company develops and produces hand tools, precision torque tools (mechanical and electronic, with measurement accuracy ranging from ±1% to ±6%), pneumatic and battery-powered tools, special tools for automotive and industrial applications, and workshop equipment — organized into seven core product categories spanning torque wrenches, hand tools, the SmartCase/SmartHolder storage system, pneumatic and power tools, special tools, workshop equipment, and workshop supplies including HD video endoscopes.

HAZET sells exclusively through a network of specialist dealers (Fachhandel) in more than 60 countries across Europe, the Middle East, Asia-Pacific, and the Americas, complemented by company-operated online shops for replacement parts and branded merchandise. Its customer base spans automotive workshops and dealerships, aviation, industrial manufacturing, electrical trade, skilled trades, maritime, two-wheeled vehicles, sanitary/plumbing, and construction, addressed through both German-engineered precision products (e.g., VDE-insulated tools to IEC 60900:2018) and service operations such as the Drehmoment Service-Center and in-house calibration laboratory.

Revenue is generated primarily through hardware sales across the seven product categories, supplemented by professional services for torque calibration and tool maintenance, and a quote-based distribution model that channels all transactions through authorized dealers. The company has no external investors, no public listing, and no disclosed financial figures; its strategic positioning is anchored by 'Made in Germany' production, multiple design and innovation awards (Reddot 2023, German Innovation Award 2022, iF Design 2021), and a 30-year co-development partnership with Porsche Motorsport that produced the Racing Tool Line in 2024.
