QJXBM12A - Williams - 12 mm Box‑End Torque Adapter with 10° offset and J‑Shank

The Williams QJXBM12A Torque Adapter is engineered for precise torque application on 12 mm fasteners located in confined, awkward, or obstructed areas. Its box‑end design offers full‑surround contact on the fastener head, greatly reducing rounding and slipping while enhancing torque accuracy — especially critical when dealing with sensitive hydraulic, mechanical, or industrial equipment.

The 10‑degree offset provides additional clearance, enabling access to fasteners hidden behind structural components, recessed mounting points, or machine framing. This makes it particularly valuable in equipment maintenance, industrial repair, and HVAC or hydraulic servicing where straight‑line access is not possible.

Designed for compatibility with the Williams J‑Shank torque system, this adapter pairs seamlessly with Williams torque wrenches and digital torque tools. Made from high‑strength alloy steel, it delivers durability, stability, and long life under heavy industrial use.
