QZXM55ADP - Williams - 55 mm Heavy‑Duty Box‑End Torque Adapter

The Williams QZXM55ADP Torque Adapter is a heavy‑duty torque head designed specifically for 55 mm fasteners commonly found in large machinery, power‑generation systems, hydraulic presses, mining equipment, and industrial infrastructure.

Its box‑end design ensures full‑engagement contact around the fastener head, providing maximum grip, minimizing rounding, and delivering consistent torque accuracy under extremely high load conditions. This makes the QZXM55ADP an essential tool when the torque values exceed what standard sockets or smaller torque adapters can safely handle.

Constructed from high‑strength alloy steel and precision‑machined for exact fitment, this torque adapter is engineered to withstand repeated heavy‑duty use. It integrates seamlessly with Williams torque systems and is suitable for use with manual, hydraulic, or electronic torque tools.
