For nearly 40 years, Allied International has been committed to satisfying what you look for in Hand Tools. We stand behind everything we build and a Guaranteed Forever warranty for the life of the product. An exclusive feature on all Pro-Grade sockets and combination wrenches, is the Dyne-Drive Torque System, which dramatically improves fastener driving performance when compared to conventional socket and wrench driving systems.
- By re-designing the socket and wrench box-end interiors to grip the sides of the fasteners rather than the corners (as in conventional tools) the contact surface area is substantially increased.
- This allows the application of up to 20% more driving torque with no slippages or fastener damage.
- In addition, many fasteners with existing rounded corners can now be worked more easily.
