Special Socket Wrench Types
Socket wrenches typically consist of a ratchet wrench with a female slot and a set of sockets to go into the slot. However, this only describes one type of socket wrench. There actually are four types of socket wrenches, and not all have socket sets. Manufacturers designed each of the four types for specific purposes. Using a socket wrench, whatever type, is fairly simple as you apply enough torque to loosen or tighten a bolt or nut. Does this Spark an idea?

Socket Set Wrench
-
As described previously, a socket set wrench consists of a ratchet and a set of sockets. Socket set wrenches come in either a hexagonal or double hexagonal configuration, each one depending on the standard used for a specific bolt. For instance, use a hexagonal socket for hexagonal-shaped bolts normally found in automotive engines. Use a double hexagonal socket for nuts shaped with 12 points or square-shaped bolts, commonly used in large machines and appliances. Socket sets come in varying depths as well. You also can find a specific socket wrench -- the impact socket that uses sockets, but provides more torque The impact socket wrench has a gun-like design construction connected to a compressed air source or to an electric power source. The air or power source allows for a more mechanical and powerful rotation of the socket resulting in phenomenal amounts of torque. Impact sockets are normally used on airplanes, specialized racing wheels, and other equipment needing quality bolting.
Tube Wrench
-
A tube wrench is a specialized socket wrench that comes in prefabricated socket handles. Use it mainly used for plumbing purposes, where piping nuts are more prone to threading damage. A basic tube wrench will have a socket head on each end of the bar, with varying measurements. A set of tube wrenches will feature varying sizes of socket heads.

Lug Wrench
-
Lug wrenches typically work for standard automotive wheels, designed specifically to loosen or tighten the lug nuts. You can choose among two typical lug wrench designs: the cross bar and the single head wrench. The cross bar has two iron bars forming a cross. Each end of the cross bar has a socket head with varying measurements. The single head wrench has one end with a socket head, and the bar bent and angled at 90 degrees. You can place a metal rod near the end of the non-socketed head, where you'll find a hole for more torque leverage.
Tuning Wrench
-
The tuning wrench is a small tool with a socket head on one end and a bar connected perpendicularly on the other end. Use it primarily to tune the strings of musical instruments, including guitars, harps and pianos.
