Finely forged wrench made of chromium-vanadium steel for long durability. LOAD CAPACITY: Hardened by heat treatment, very high load-carrying capacity. Special room technology: Very precise and high quality pages. The profile naturally adjusts to different pages. The angles of the nuts are not matt. The keys thereby have a considerable advantage as compared to the conventional 6 and 12-edge profiles. ERGONOMICS: Ergonomically designed profiling and marking enable high torque transmission. The finely forged surface ensures high working comfort and easy cleaning of the tool. 15° angled key head for easy working in hard to reach places. 30° retainer angle: Thin-walled ring head for work even in places that are difficult to access. NF ISO 1711-3318-691 / DIN 899-3113. Made in our factories.This text is machine translated.
