Buying A Set?

You can buy ratchet ring spanners singly or in a set. If you’re likely to need them in different sizes or for different purposes, a set could be the best investment for you.  If you’re going to choose a set, you need to decide how many spanners you require. Some sets have just a few, perhaps 5. Others have over 20 to choose from.


Of course, the finish of your spanner will have an effect on how nice it looks. However, that isn’t the true purpose of a finish. It should offer optimal protection from corrosion and damage too.

There are various finishes to choose from:

  • Polished chrome – these are common and visually attractive. They’re also fairly durable and offer good protection from corrosion and rust. On the downside, this finish can make spanners slippery if oil or water gets on them.
  • Black oxide (1) – this is a more affordable finish. It offers good protection from chipping and scratches but not so much from corrosion and rust.
  • Nickel – this is one of the least common finishes. It isn’t especially durable and can chip and scratch easily. It is quite an affordable choice though.


If you’re using your spanner in a tight location with minimal room for turning the wrench, the ratchet must engage immediately when you begin turning. You need at least 72 teeth for this to occur. If possible, a 90 tooth spanner is best.

Ratcheting Spanner FAQs

A ratcheting spanner uses a gear and pawl mechanism(2) which creates the ratcheting motion one way while also allowing free spinning of the wrench in the other direction. 

Once the spanner is turned, the pawl will lock onto every tooth in the gear. This creases a very high level of toque inside the socket. 

When you get to your desired arc limit, it’s possible to return easily to your initial position with no loss of torque and with no need to release the fastener.

You don’t technically need to buy a ratchet spanner if you have a regular spanner in your toolkit. However, it can make your life a lot easier. Its ratchet feature enables you to simply turn the bolt by a few degrees before returning to the starting point with no need to remove the spanner or undo your work.

Also, the combination box and open head design and thin beam give this design even greater versatility. Essentially, a ratcheting spanner can do exactly what your existing spanner does but more efficiently. It is, therefore, the best option if you want to remove fasteners at a higher speed.

Sockets and ratcheting spanners perform similar functions. However, a socket may be switched on just one handle. A ratchet spanner, on the other hand, is just one size. 

Socket spanners may also experience clearance issues when working in tight spaces. Ratchet spanners, meanwhile, have a thinner design. This allows them to get into even awkward spaces while requiring a minimal amount of clearance.

If you use a combination spanner, you have to align it with the fastener or bolt and turn it before disengaging. This returns the spanner to the starting point. You then have to put the end back on the fastener and turn it once more. 

If you’re a professional, you may be able to do this fairly quickly. But it can still be difficult to carry out the task quickly if the fastener is difficult to see or in a tricky location.

A ratcheting spanner means you only need to find the bolt once. After attaching the ratcheting spanner head it will stay there until you’ve completed the job.
