Wright Tool Wright wrenches feel as good as they look. And they have a reserve of strength for tough jobs. They feature the patented Wright Drive; which provides more torque with less fastener damage; distributing stress evenly over a larger contact area and away from the fastener corners. They're ideal for applications ranging from standard nuts and bolts to aerospace fasteners. We also offer striking wrenches for extra-heavy-duty use.
