The Mayhew Steel 9-Piece Metric Twisted Hex Key Allen Set (brand part no. 45053) is the metric counterpart to Mayhew’s SAE twisted hex key set, built with the same reinforced shank design. Mayhew Steel forges each metric key’s shank with a visible twist that adds torsional strength, helping the key resist snapping under heavy torque on a stubborn or thread-locked metric fastener. For a bench that services European-pattern rifles, imported optics, or metric mounting hardware, this set covers the metric sizes needed without sacrificing the durability advantage the twisted-shank design offers over a plain straight key.

Key Specifications
