A “spanner” is a tool used for turning objects such as nuts, bolts, and other fasteners. It is known as a “wrench” in some regions, particularly in North America. Spanners come in various shapes and sizes, each designed for specific tasks. They are an essential tool in mechanical work, plumbing, carpentry, and other industries where fasteners need to be tightened or loosened.

Spanners typically have an opening or “jaw” that fits around the fastener, and they can be either adjustable or fixed. Here are a few common types of spanners:

  1. Open-Ended Spanner: This spanner has U-shaped jaws at both ends. It is designed to grip two opposite faces of a nut or bolt.
  2. Ring Spanner (Box Wrench): This spanner has a circular ring-like end with an enclosed jaw. It provides a more secure grip on the fastener and is less likely to slip off.
  3. Combination Spanner: This type of spanner has an open-ended jaw at one end and a ring or box-like jaw at the other, offering versatility for different types of fasteners.
  4. Adjustable Wrench: Also known as an adjustable spanner, this wrench has a movable jaw that can be adjusted to fit different sizes of fasteners. It’s a versatile option for various tasks.
  5. Socket Wrench: A socket wrench, often used with socket attachments, allows for easy tightening or loosening of fasteners in tight spaces.
  6. Pipe Wrench: This type of wrench is designed for gripping and turning pipes and other cylindrical objects.
  7. Torque Wrench: A torque wrench is a specialized spanner that allows you to apply a specific amount of torque to a fastener. It’s essential for tasks where precise torque is crucial.

The choice of spanner depends on factors such as the size of the fastener, the type of work being done, and the space available for maneuvering the tool. It’s important to use the correct spanner for the job to avoid damaging fasteners or the tool itself.

Remember that terminology can vary by region, so while “spanner” is more common in some parts of the world, “wrench” is the preferred term in others.
