About us
Streicher Maschinenbau GmbH is an owner-managed family company based in Kressbronn am Bodensee. For over 80 years, the company has been developing and manufacturing thread tapping machines for the production of internal threads, which are primarily used in the fastener industry and the automotive supply industry. The product range includes two-spindle through-feed thread tapping machines (TOP-CUT), single-spindle reversing thread tapping machines (VARIMAC, UNI-CUT), the indexing dial machine VARIMAC 20flex, and thread rolling machines for ovalization of nuts (DW30), covering thread sizes from M3 to M64. Development and design are carried out 100% in-house, prototypes are produced using 3D printing; with a vertical integration of 80%, mechanical and electrical assembly is also performed internally. In total, more than 2,000 Streicher machines are in use in more than 70 countries, including Italy, Spain, Turkey, the USA and Asia.

Manufacturing & Processes
Two-spindle through-feed thread tapping machine
Fully automatic thread tapping of standard, bossed, flange and round nuts with through threads using the through-feed principle, threads M5–M33, up to 19,700 pcs/hour.
Single-spindle reversing thread tapping machine
Reversing drilling spindle for through and blind threads on cap, hex flange, round and weld nuts as well as special parts, with torque monitoring.
Indexing dial machine / multi-spindle machining center
Up to 10 machining spindles for drilling, threading, countersinking, chamfering, reaming, gauging and face milling in a single pass, repeatability 0.01 mm.
Single-spindle reversing thread tapping machine (mechanically controlled)
Affordable entry-level variant with cam disc control and PLC monitoring, in which scrap threads are virtually eliminated.
Thread rolling machine / ovalization machine
Production of all-metal prevailing torque nuts by partially ovalizing the nut body, threads M10–M33, deformation force up to 120 kN.
