QJXM9A - Williams - 9 mm 12‑Point Box‑End Torque Adapter with J‑Shank

The Williams QJXM9A Torque Adapter is engineered for precision torque application on 9 mm fasteners, commonly found in compact mechanical systems, hydraulic fittings, industrial equipment, and fine‑mechanical assemblies.

Its 12‑point (double‑hex) box‑end head enhances accessibility and fastener engagement, providing more alignment angles than traditional 6‑point designs. This is especially beneficial when working in tight or obstructed areas where swing‑arc is limited.

The full‑contact wrap‑around box‑end geometry delivers maximum surface engagement on the fastener, reducing rounding, improving grip stability, and ensuring reliable torque transfer. This gives the QJXM9A a significant advantage over open‑end torque heads — particularly when dealing with small hardware where precision is critical.

The robust J‑Shank interface provides a secure, rigid connection with Williams torque wrench systems, ensuring proper alignment and consistent, repeatable torque accuracy. Constructed from premium high‑strength alloy steel, the QJXM9A withstands demanding torque cycles, vibration, shock loads, and harsh industrial environments while maintaining durability and precision.

This torque adapter is ideal for technicians working with compact hydraulic systems, machinery assemblies, instrumentation, mechanical repair, and maintenance applications requiring high‑accuracy torque on small fasteners.
