Spanners are an indispensable tool in any workshop or DIY kit. They are used to tighten or loosen nuts and bolts. There are different types of spanners that are suitable for different purposes and applications.

An important factor in choosing the right spanner is the width across flats. This refers to the diameter of the nut or bolt that the spanner is intended to grip. The spanner size is usually given in millimetres and can vary from tool to tool.

Another important factor is the type of spanner. There are many different types of spanners, including open-end spanners, open-end spanners, box spanners and ratchet spanners. Each type has its own advantages and disadvantages and is suitable for different applications.

Open-ended spanners are the simplest type of spanner and consist of a straight bar with an open end. They are designed for use on hex nuts and bolt heads and are best suited for applications where space is limited.

Open-ended spanners have a jaw opening at both ends and can be used on two different sizes of nuts and bolt heads. They are usually stronger than open-end spanners and can withstand higher torques.

Ring spanners have a closed ring at both ends and therefore cannot be used on other sizes of nuts or bolt heads. However, they offer a better fit and are less prone to damage the nut or bolt head.

Ratchet spanners are a very practical type of spanner as they allow bolts or nuts to be tightened or loosened quickly and easily without having to remove the spanner from the nut or bolt head. They are particularly useful in tight spaces or when the work area is difficult to access.

Overall, there are many different types of spanners to suit different applications and purposes. Choosing the right spanner depends on the spanner size, the type of nuts or bolt heads and the specific application. With a high-quality spanner, you can work effectively and get your job done quickly and easily.
