The wrenches are made from alloy tool steel 31CrV3 with chromium and vanadium, outperforming standard CrV steel in strength, rigidity, and wear resistance.
The combination of an open end and a ring end enables flexible work—quick loosening and precise tightening of bolts and nuts without rounding edges.
The practical selection of 8, 10, 12, 13, 14, and 17 mm covers most common repairs in the home, auto workshop, and industry.
This professional combination wrench set includes 8, 10, 12, 13, 14, and 17 mm wrenches. Each wrench has an open end and a ring end for secure grip on nuts and bolts. Thanks to the 31CrV3 alloy tool steel with chromium and vanadium, the wrenches deliver superior performance and reliability.
Optimized head geometry increases force transfer and reduces the risk of damaging fasteners. The surface finish further contributes to wear resistance and corrosion protection, making the wrenches suitable for everyday use in demanding conditions.
