KS TOOLS 503.4541 GEARplus Juego de llaves de carraca de anillo reversible, 4 en 1, 8x9x10x11 mm, cromo-vanadio

In a busy workshop, a mechanic reaches for a single tool to handle four common fastener sizes. The KS TOOLS 503.4541 GEARplus reversible ratchet ring spanner combines 8, 9, 10, and 11 mm openings in one compact head, eliminating the need to switch between separate wrenches. Its fine-tooth ratchet mechanism and low-profile design allow access in tight engine bays and under dashboards, while the reversible lever lets you change direction without removing the tool from the fastener.

Why choose it

The GEARplus ratchet system delivers a 5° working arc, allowing you to turn fasteners in areas where a standard wrench cannot swing.

The matt chrome finish resists rust and makes the tool easy to clean after a shift.
