Types of Spanners:- Spanners are used more often than any other tool for tightening or opening different jobs. Spanners are constructed of (material of construction) generally forged steel or carbon steel. These spanners are found in a wide range of shapes & sizes, respectively, per the different job requirements. Apart from that, they are also used for tightening & loosening to any given job or screw.
Types of Spanners
Spanners types are following listed below.
1. Open End Spanners
In open-end spanners, as the name suggests, one end is open, which provides the ability to hold the nuts or bolts ‘ heads or grip them to either tighten or loosen them. An open-end spanner is also known as a single-end spanner; their known size is basically the difference between their respective jaws. The selection of spanner would be the subject based on the nut & bolt sizes to be used.
2. Double End Spanners
In the double-end spanners, both ends are opened to hold the bolts & nuts with the help of this equipment. In double-end spanners, both ends are formed at an angle difference of 15 -30 degrees in b/w their body. These spanners are the most widely used in operation.
3. Ring Spanner
In these types of spanners, one or both ends are round rings that are made up to grip nuts & bolts to tighten or lose them. These rings are constructed downward & upwards to each other at their respective different ends. Inside of these rings (each), teeth are constructed for hexagonal heads so nuts & bolts can be gripped easily. There are some types of ring spanners that are not bent.
4. Socket Spanner
Socket spanners are found in the form of round sockets; at the one end, a square hole is formed, while on the other end of the socket, spanner grooves are provided with respect to the sizes of nuts & bolts as likes of a spanner. Inside the square hole, Tommy’s bar is fixed; its shape is also square. These are available in sixes in all forms of sets.
5. Box Spanner
Box spanner is made up of thin pipes on one end or both ends equipped with six sides for grip nuts & bolts. Holes are formed across the rod of the spanner at one or both ends. Box spanners are used in deeper spaces.
6. Combination Spanners
In this spanner, one end is open, and the whole other end is made like the ring spanner is made. Both ends of this type of spanner are of equal sizes.
7. Hook Spanner
These are made up of nuts with “o” nuts holes on their body. There are no faces on their nuts. So, the pin of the spanners was fixed with the hole & performed the function of tightening or losing them.
8. Adjustable Spanner
Adjustable spanners are special types of spanner tools. These are also known as screw wrenches. Its jaws can be expanded or narrowed to tighten or lose the nut. They are used for those nuts where no other spanner fits well enough for better operation performance.
