QZO42ADP - Williams - 1‑5/16" Open‑End Dual‑Pin Torque Adapter – Z‑Shank

Williams QZO42ADP 1‑5/16" Open‑End Dual‑Pin Torque Adapter – Z‑Shank
The Williams QZO42ADP 1‑5/16" Open‑End Dual‑Pin Torque Adapter is engineered for industrial technicians who require maximum strength, accuracy, and secure tool retention when working with large fasteners in demanding environments. Featuring a dual‑pin Z‑shank connection, this torque head delivers enhanced stability and anti‑slip security—ideal for high‑torque operations where tool movement cannot be tolerated.

Its slim open‑end profile provides superior accessibility in tight, obstructed, or recessed locations where traditional box‑end torque heads are ineffective. Combined with Williams' premium alloy‑steel construction and precision machining, the QZO42ADP ensures reliable, repeatable torque transfer even under extreme load conditions.

Built for rugged industries such as oil & gas, mining, utilities, power generation, industrial maintenance, and heavy‑equipment service, this torque adapter is a proven choice for technicians who demand long‑lasting performance.
