QXXM19A - Williams - 19 mm Box‑End Torque Adapter with X‑Shank

The Williams QXXM19A Torque Adapter is engineered for technicians who require accurate, repeatable torque application on 19 mm fasteners. Commonly used across industrial machinery, hydraulic systems, mechanical equipment, and heavy‑equipment servicing, this torque head delivers exceptional reliability and performance.

The box‑end head provides complete fastener engagement, reducing rounding, improving load distribution, and ensuring consistent torque transfer — a substantial upgrade over open‑end torque adapters, especially in high‑load or torque‑critical applications.

With the robust X‑Shank interface, the QXXM19A securely connects to compatible Williams torque wrench systems, maintaining consistent alignment and rigidity during torque operations. Built from premium high‑strength alloy steel, this adapter withstands repeated torque cycles and harsh industrial conditions without compromising accuracy or durability.

This torque head is ideal for technicians performing industrial maintenance, factory repair work, hydraulic equipment servicing, field mechanical support, and general heavy‑equipment assembly.
