The Faithfull FAIHK170MLA is a 17mm long arm hexagon key, the largest size in this metric range for the most substantial industrial fastening applications. This professional-grade tool is essential for major infrastructure projects, heavy machinery assembly, and large-scale engineering installations where maximum torque capacity is critical. The 17mm configuration delivers uncompromising strength when working with the largest industrial socket screws. Manufactured from fully hardened chrome vanadium steel, this key provides exceptional durability and resistance to deformation under extreme loading. The long arm design maximises leverage, enabling operators to generate substantial torque whilst minimising physical strain. Chamfered edges protect both the tool and fitting surfaces, ensuring precision is maintained even during high-stress operations. Clear size marking facilitates rapid identification in professional workshop environments.
