Adjustable Hook Wrench

The Adjustable Hook Wrench is a versatile, non-sparking hand tool engineered to tighten or loosen various sizes of round nuts, threaded collars, and retaining rings. Unlike fixed hook spanners, this wrench features an adjustable hook arm, making it compatible with a wider range of diameters. It is an efficient solution for tasks where frequent size changes are required, eliminating the need to switch tools.

Manufactured from premium-grade Beryllium Copper (Be-Cu) and Aluminum Bronze (Al-Br), this wrench ensures safe operation in environments where sparks must be strictly avoided. These non-sparking alloys are ideal for explosive or flammable atmospheres, such as those found in oil refineries, chemical plants, gas distribution facilities, and mining operations. Additionally, the materials are non-magnetic and corrosion-resistant, making the tool suitable for cleanroom and marine use.

The die-forged construction enhances the tool’s mechanical strength, providing excellent durability and reliability under repeated use. The adjustable hook mechanism is designed to lock securely in place, offering stable engagement with round or slotted components. The ergonomic handle ensures user comfort and torque control, even during extended operations or in confined working spaces.
