Faithfull Hexagon Key 17.0mm FAIHK170M

The Faithfull 17mm Hexagon Allen Key is a heavy-duty professional tool designed for the largest hexagon socket applications. This substantial size is essential for industrial machinery, heavy construction equipment, and large-scale structural assemblies where maximum torque and leverage are required. Manufactured from fully hardened chrome vanadium steel, this 17mm key delivers exceptional strength and rigidity for the most demanding high-torque applications. Chamfered edges protect both the tool and expensive socket fittings from damage during use, whilst clear size markings enable rapid identification in busy workshop environments.
