The ATD-6510 is a 10-piece metric ratcheting wrench set engineered for automotive technicians and service professionals who need both extended reach and multi-profile fastener access. Extra-long lengths from 12.2″ to 17.6″ deliver leverage where standard wrenches fall short.

Each wrench features a 72-tooth flex-head ratchet box end that pivots up to 180° for hard-to-reach fasteners, plus a non-ratcheting 12-point zero-degree offset end for breaking loose stubborn hardware. The universal spline drive engages six profiles: spline, 6-point, 12-point, star, square, and rounded. Sizes: 10–19mm. Lengths range from 12.2″ (10mm) to 17.6″ (19mm).

Compatible with passenger cars and light trucks from domestic and import manufacturers (1990–2026). Ideal for automotive technicians performing engine, drivetrain, and suspension service in tight spaces, as well as lift trucks, agricultural equipment, heavy equipment, on/off-highway diesel vehicles.
