Harden 540117 7PCS Gear Spanner Set – Fast, Efficient & Professional
The Harden 540117 7PCS Fixed Combination Gear Spanner Set is a premium toolset designed for fast and efficient fastening in automotive, workshop, and industrial environments. Featuring a ratcheting (gear) mechanism on the ring end, this set allows continuous operation without removing the wrench—saving time and effort.
Manufactured from high-quality Chrome Vanadium (CR-V) steel, each spanner is forged, hardened, and tempered for superior durability and long-lasting performance. The 72-tooth ratchet head provides a fine 5° swing arc, making it ideal for working in tight and confined spaces.
With a slim profile design, these gear spanners offer easy access to narrow areas while maintaining strength and precision.
