Hartig GmbH & Co KG

What Hartig GmbH & Co KG does

Hartig GmbH & Co KG is a German family-owned precision mechanical components manufacturer founded in 1920 in Aschaffenburg, where it operates a single integrated production facility. Its activity spans two product families: positioning components (precision lead screws, micrometer heads, fine adjustment screws, and custom-built sub-assemblies) and hand-held measuring instruments (outside and inside micrometers, plus accessories). All production steps — turning, hardening, cylindrical grinding, thread grinding, assembly, and laser marking — are performed in-house, supported by a temperature-controlled metrology laboratory. The company holds ISO 9001:2015 certification and manufactures its hand measuring instruments in accordance with ISO 3611 and DIN 863:2017. Standard catalog offerings include over 160 micrometer head versions and over 176 fine adjustment screw variants, with ground lead screws achieving repeatability error below 1µm and positional error below 3µm per 50mm.

The company serves enterprise customers in laser and photonics, microscopy, precision mechanical engineering, and machine-shop quality inspection. Named reference customers include Physik Instrumente (PI), OWIS GmbH, Hoffmann Group, and Märzhäuser Wetzlar. Its go-to-market is consultative, direct enterprise sales: customers submit inquiries via website contact forms, after which Hartig provides individualized consultation, design, and custom construction for non-standard requirements. Distribution is direct and build-to-order, with no e-commerce or online store. Pricing is catalog-based (multiplier on list price, ex-works) for standard products, with engineered custom quotations for modified and bespoke components. Revenue streams are diversified across one-time sales of standardized components, custom-engineered assemblies, and services including calibration, repair, and laser marking.

The business is owned and operated by the fourth generation of the founding family, with Stephan-Leander Klein and Dr. Jakob Hartig (great-grandsons of the founder) having assumed management in 2023. The legal entity is a GmbH & Co KG, with Hartig Beteiligungs GmbH acting as the general partner. The company employs approximately 30 highly qualified staff, all based at the Aschaffenburg location, and operates without external funding, acquisitions, or formal partnerships.
