QJXB20A - Williams - 5/8" Box‑End Torque Adapter with 10° offset and J‑Shank

The Williams QJXB20A Torque Adapter is engineered for accurate torque application on 5/8" fasteners located in confined, angled, or obstructed spaces. Its box‑end head provides full‑contact engagement around the fastener, significantly reducing rounding and slippage while improving torque consistency — essential for high‑torque mechanical, hydraulic, and industrial applications.

The integrated 10‑degree offset enhances access by allowing technicians to reach bolts positioned behind guards, recessed housings, machine framing, or structural obstructions. This makes the QJXB20A a highly valuable tool during equipment maintenance, hydraulic system service, industrial repair, and heavy‑equipment work.

As part of the proven J‑Shank torque adapter family, this torque head connects securely with Williams torque wrenches and digital torque systems. Constructed from high‑strength alloy steel, it delivers long‑lasting durability and dependable performance in demanding environments.
