* Hexagonal cap specifically forged for use with impact tools * Precision cold-forged and hardened chrome vanadium steel * Clearly legible, laser engraved dimensions and industrial phosphate coating * Thick-walled design ensures stability and durability for repeated high torques * Hole in the side wall for attachment to the tool via a ball closure mechanism or bolt Hexagonal cap specifically forged for use with impact tools. Precision cold-forged and hardened chrome vanadium steel. Easy-to-read, laser-engraved dimensions and industrial phosphate coating for effective corrosion protection. Thick-walled design ensures stability and durability for repeated high torques. Hole in the side wall for attachment to the tool via a ball closure mechanism or bolt pin.
