PROTO has been making durable, high-quality hand tools in the USA for more than 100 years, having grown from a small machine shop to a worldwide supplier. Our tools are developed according to strict industry standards, with features that let users work quickly and efficiently, including double nickel-chrome plating to help protect against corrosion on sockets, wrenches, ratchets, and torque tools, and thinner outside diameters on box end wrenches to better reach obstructed 12-point fasteners. We are exhaustive in our efforts to make safe tools and provide tool safety education. For technical support call (800) 800-TOOL or email
