Torque Adapter 21 mm Box End with Y Shank - Williams
The Williams QYXM21A Torque Adapter is engineered for dependable and repeatable torque application on 21 mm fasteners typically found in industrial machinery, hydraulic equipment, mechanical assemblies, and heavy‑equipment maintenance.
Its box‑end design provides full‑wrap fastener engagement, enhancing grip stability, reducing rounding, and ensuring superior torque transfer — making it a far more reliable option than open‑end torque adapters, especially in high‑load or torque‑critical operations.
The rugged Y‑Shank interface offers a secure and rigid connection to compatible Williams torque wrench systems, ensuring proper alignment and consistent torque output whether using manual or electronic torque tools. Crafted from premium high‑strength alloy steel, the QYXM21A is built to endure harsh working conditions, extreme torque cycles, and daily industrial wear without loss of performance.
This torque head is ideal for technicians performing industrial maintenance, mechanical repair, hydraulic service, equipment assembly, and field‑service operations requiring precise torque and long‑term durability.
