- SP Tools Speed Drive allows the open end to quickly ratchet fasteners without removing the spanner from the fastener. This design results in much fastener bolt and nut removal where only an open end spanner can be used
- SP Tools patented Gear Drive spanners are precisely machined with deeper gears for greater torque loading and reliability with 72 teeth that only require 5° of space per turn.
- Reversible - Simply flip the spanner to change rotation direction
- Chrome Vanadium Steel (Cr-V) for high strength & durability
- Meets & exceeds international ANSI & DIN standard
