The ARES 6-pc 120-Tooth Metric Non-Slip Ratcheting Wrench Set, No. 35021, includes non-slip ratcheting wrenches in 10mm, 12mm, 13mm, 14mm, 15mm, and 17mm sizes as well as a durable wrench holder that secures wrenches in place. Constructed of chrome vanadium steel with a polished chrome plated finish for added durability and corrosion resistance, each wrench is size stamped for easy identification. The ratcheting box ends of these wrenches feature 120 teeth and operate with just a 3-degree swing arc for ease of use even in spaces with limited access. The patented, non-slip box ends reduce slippage during fastener adjustment to help avoid rounding and work on fasteners up to 85 percent rounded.
