First choice wherever a ring spanner does not work. Ideal for tightening bolts on brake lines, tie rods, exhaust gas temperature sensors, diesel lines or air conditioning pressure sensors. Like an open ring spanner, it can be plugged on the side of union nuts or screws. Articulated arms with locking spring and integrated opening aid provide for self-clamping effect and power transmission on the edges of the screw head. Ratchet effect enables quick follow-up. In addition, the identification of the actuation direction on the key head ensures easy handling. https://elecena.pl/product/28005754/stahlwille-41101212-240-12-15-32-ratcheting-single-ended-open-ring-spanner-12-mm 2025-03-09 https://elecena.pl/product/28005754/stahlwille-41101212-240-12-15-32-ratcheting-single-ended-open-ring-spanner-12-mm 2026-07-02
