So, you want to build the ultimate hand tool collection, you better start with a ratchet wrench. The core of a mechanic’s toolbox, this humble hand tool is versatile and the key to unlocking pretty much any part of a car’s internals.
Unlike wrenches or standard spanners, ratchet wrenches have a ratcheting pawl mechanism inside, allowing the tool to reassume its original position without moving the nut or bolt it is tightening. Ratchet wrenches are especially useful if you’re tightening or loosening a subject without much room to manoeuvre, say in the deepest bowel of an engine bay.
Instead of removing the tool completely and resetting it again, the ratchet can be pulled back with a few clicks and the wrench is back in position – greatly expediting the tightening process. Ratchet wrenches are also commonly known as socket wrenches, as many examples use attachable sockets to rotate the nut or bolt. These sockets are interchangeable, with most ratchet wrenches including a starter set of several different sizes as standard.
However, most standard ratchet wrenches do not feature a torque gauge to precisely and accurately measure the torque delivered onto a subject. Some car manufacturers recommend certain bolts be tightened to a set level, but to carry this out accurately will require a more expensive torque wrench.

Best premium ratchet wrench
What we like so much about this particular tool is the rotating head for reaching awkward locations and the inclusion of a flywheel for quicker working. Partner this with Wera's ergonomic and extremely comfortable Kraftform handle and this ratchet wrench really prices why it commands such a price premium. If all of that wasn't enough, it can even work as a screwdriver.
Pros
- Exceptionally well-designed and built
- Ergonomic handle
Cons
- Expensive
| Contents: | One ratchet wrench |
| Sizes covered: | N/A |
| Ratchet size: | 3/8" |
| Tool material: | Chromium-vanadium steel |
Best ratcheting spanners

This set comes in a velcro-sealed bag, but the spanners could also be hung from their ratchet rings for an authentic workshop aesthetic.

Cons

| Sizes covered: | 8-19mm |

Best mini ratchet wrench set
Rrp: £20.50

Cons
- Not suited to big nuts
| Contents: | One ratchet wrench, two holders (universal and socket), 19 screwdriver bits, five sockets, one storage case |
