Six Varieties of Wrenches (Materials & Head Offsets)

For every job there is a tool, and when it comes to wrenches, there are a plethora of choices. Let’s take a look at the six most common types of wrenches and some of the materials used to create them.

Head Offsets

  • Open-end wrenches: These have U-shaped openings on either end and are used for tightening or loosening nuts and bolts.
  • Box-end wrenches: These have enclosed ends that grip the sides of nuts and bolts for more torque.
  • Combination wrenches: These have one open end and one box end, making them versatile for different types of fasteners.
  • Adjustable wrenches: These have jaws that can be adjusted to fit a variety of different sizes of nuts and bolts.
  • Socket wrenches: These use sockets that fit over nuts and bolts, allowing for more precise torque and access to tight spaces.
  • Torque wrenches: These are designed to apply a specific amount of torque to a fastener, which can be important for certain applications where over- or under-tightening can be dangerous.


In terms of materials, wrenches can be made from a variety of metals, including steel, aluminum, or titanium. Head offsets can also vary depending on the type of wrench, with some having straight heads and others having angled heads for better access in tight spaces.
