What are the 10 different types of spanners and their uses?

It’s difficult to picture a toolbox without a spanner set. There are many different types of spanners on the market, including the following:

Open End Spanners

As the name implies, open-end spanners have one open end that may be used to hold nuts or bolt heads or grasp them to tighten or loosen them. You must adjust the position of the open-end spanner after each turn while using it. It is the most often used tool and can be found in most people’s toolboxes. It’s either both or one of the ends is C-shaped. It’s excellent for tight places with only one side of the nut accessible.

Ratchet Spanners

The major advantage of a ratchet spanner is that they don’t need to be withdrawn from the nut and reset in between turns when room for a full rotating arc is restricted. This spanner is useful in a variety of situations, but it’s especially useful in tight spaces.

Adjustable Spanners 

Adjustable spanners may be used to fit a variety of screws and bolts, eliminating the need to carry a variety of different-sized spanners. The problem is that they might be difficult to use since they don’t always lock securely onto the nut or bolt.

Box Spanners

 Box spanners’ elongated form makes them ideal for reaching nuts that are deeply recessed or otherwise difficult to reach, and most Tommy bars’ sliding mechanism allows users to make the most of any available area while delivering appropriate torque.

Combination Spanners

Combination spanners are tools with two functional ends. On one end, it has an open-ended profile, while on the other, it has a closed-loop profile. This single tool performs the duties of two spanners at the same time.

Hammer Spanner

The hammer spanner is typically used to tighten flange fittings and fasteners with big flanges. High-strength hammer spanners can also be used to remove frayed or corroded nuts and bolts. Essentially, this heavy-duty spanner is used to work with metal, plumbing, and electricity.

Crowfoot Spanner

When you don’t need to remove the surrounding parts first, they’re ideal for handling bolts that are firmly embedded in the machine’s body. 

Flare Nut Spanner 

It’s sometimes referred to as a line spanner. These spanners are particularly helpful on fragile metals that can be damaged by open-ended spanners, such as those used in plumbing.

Hook Spanner 

These spanners are designed for nuts that do not have holes around the perimeter. These nuts don’t have any faces on them. As a result, the spanner’s pin becomes lodged in the hole and performs the function of rotating it to open or tighten it. 

Alligator Spanner

They’re only seen in movies anymore since they’re intended to handle square nuts and bolts, which are becoming increasingly scarce
