Socket sets include a variety of sizes to fit the nuts and bolts for your repair job. However, not all sets are created equal. Here are some things to keep in mind while selecting your socket set for your tool box.

A Good Alloy
Alloys are mixture of a metal and another element that are put together for a specific purpose. For example, steel is an alloy of iron and carbon; which of course has many applications from kitchen utensils to hand tools. However even alloys of steel exist to take on different tasks. Chrome vanadium steel is often used in sockets. This alloy is known for its high strength and durability.

Impact vs Standard
Does your repair job require an impact wrench? If it does, be sure to purchase sockets that are designed for impact applications. Impact sockets are designed to withstand the high torque created by impact tools. It would seem common sense, but many people use standard sockets with impact tools. These sockets often fail causing pieces to break away that may jeopardize your safety.

Metric and SAE Units
Having the right size socket is very important. Some socket sets come only in SAE (inch) measurements and others are in metric (millimeters). Some sets have both. Think about where the product was built, as foreign products tend to use metric nuts and bolts, while U.S. products may have inch-based sizes. An alternative is to purchase a metric and SAE set to cover both.
