What GSR does

GSR Gustav Stursberg GmbH is a German manufacturer and wholesale distributor of precision threading tools headquartered in Remscheid, Germany. Founded in 1889 and operating continuously for more than 130 years, the company produces thread taps, machine taps, die holders, hand taps, thread-repair coil systems (Coilrepair), drilling and countersinking tools, and measuring instruments, plus the e-Tapping line for cordless-screwdriver-based threading and a GSR SILVER sub-brand spanning machine taps, tool holders, DIN 1814-compliant tap wrenches, guide bushings, and cutting-edge assistants. Manufacturing is supported by an in-house Ideenschmiede (innovation unit) that uses 3D CAD design and 3D printing for prototyping. The company is ISO 9001 and DIN EN ISO 14001:2015 certified and operates from a single Remscheid facility.

GSR serves two principal customer segments: industrial manufacturers and workshops requiring precision threading tools for production, maintenance, and repair, and wholesale/trading companies that buy the company's products for resale, including under private-label arrangements. Pricing is quote-based and not publicly disclosed; standard commercial terms include 30-day net payment (or 10 days with 2% Skonto), ex-works pricing excluding VAT. Distribution combines an 8-language corporate website, a transactional e-commerce storefront at gewindewerkzeuge.com, direct sales from headquarters, and regional channel partners (e.g., an official trading representative in Russia). The company advertises an international customer base covering Germany, France, Italy, Spain, Portugal, Poland, Russia/CIS, and China, and actively participates in trade fairs such as the China International Hardware Show 2025.

Revenue is generated almost entirely from one-time hardware sales across the core tool range, supplemented by licensing/royalty-style revenue from private-label and trading arrangements. Supporting revenue mechanics include a free mobile Thread Calculator app for iOS and Android and a 3D printing service for custom prototypes, both functioning as customer-acquisition and retention assets rather than material revenue streams. The company is privately held and family-owned under Managing Director Max Philipp Blombach, with no disclosed outside investment, parent company, or institutional ownership.
