QXXM20A - Williams - 20 mm Box‑End Torque Adapter with X‑Shank

The Williams QXXM20A Torque Adapter is built for technicians who need accurate, repeatable torque application on 20 mm fasteners used across industrial machinery, hydraulic equipment, mechanical systems, and heavy‑equipment maintenance.

Its box‑end configuration provides full‑surface contact around the fastener head, maximizing grip, reducing rounding, and improving torque transfer compared to open‑end torque attachments. This makes it ideal for torque‑critical or high‑load environments where precision is essential.

The rugged X‑Shank interface ensures a solid, stable connection to compatible Williams torque wrench systems — whether manual, digital, or hydraulic. Manufactured from high‑strength alloy steel, the QXXM20A is engineered to withstand frequent torque cycles, harsh environments, and long‑term industrial use without compromising performance.

This torque head is perfect for technicians servicing hydraulic linkages, industrial machinery, mechanical drive components, heavy‑equipment assemblies, and manufacturing systems.
