New 20mm Bi-Hex Wrench — Built for HGV brake work
Laser Tools expands its heavy-duty HGV range with the introduction of the HGV Brake Caliper Wrench (part number 9141), a 20mm bi-hex slogging wrench engineered for the demanding job of releasing and refitting brake caliper mounting bolts on commercial vehicles.
These bolts are typically torqued to high levels, and the 9141 is built to take the strain. With a robust 3/4" drive and dual impact faces, this wrench is designed for use with a hammer or mallet, providing the force needed to crack stubborn fasteners loose.
Manufactured from toughened S45C steel (HRC 38–42) and finished with black phosphate for corrosion resistance. For tightening, the wrench features a correction factor formula etched directly onto the body—essential when used with a 3/4" torque wrench to ensure precise torque application.
Size: 20mm Bi-Hex (12-point) with 3/4"D slogging drive.
Ideal for loosening/tightening HGV brake caliper bolts torqued to high spec.
Features tightening torque correction factor etched on the wrench body.
