Understanding Spanners: Types and Uses

Spanners are a type of tool used to tighten or loosen bolts and nuts. They are typically made of metal and have a long, thin shaft with a handle on one end and a wrench or socket on the other end. The wrench or socket is designed to fit over the bolt or nut and provide a secure grip, allowing the user to apply torque to tighten or loosen the fastener.

There are several types of spanners available, including:

1. Open-end spanner: This is the most common type of spanner and has an open end that can be used to fit over any size bolt or nut.
2. Box-end spanner: This type of spanner has a closed end that is designed to fit over bolts and nuts with a specific size.
3. Combination spanner: This type of spanner has both open and closed ends, allowing it to be used on a variety of different fasteners.
4. Adjustable spanner: This type of spanner has an adjustable jaw that can be set to fit over bolts and nuts of different sizes.
5. T-handle spanner: This type of spanner has a T-shaped handle and is typically used for tightening or loosening large bolts and nuts.

Spanners are an essential tool for anyone who works with fasteners, as they provide a secure grip and allow the user to apply the correct amount of torque to tighten or loosen the fastener.
