Combination ratchet spanner is a hand tool designed for works with polygonal fasteners. It has the working parts on both ends: on the one end, there is an open-end spanner, on the other – a ring or flare nut spanner fitted with a ratcheting mechanism. The open-end head is suitable for works with fasteners located in tight spaces which makes it impossible to grip the fastener head around. The ring spanner is used to tighten or loosen fasteners in easy-to-reach places.
Combination ratchet spanners: 6 important facts
By the design, there are solid and swivel devices. The former ones do not have any movable parts, they are robust and cheap. The latter ones feature a ring head attached to the handle with a swivel joint. This enables it to rotate to 180 degrees to ensure convenient work in hard-to-reach places.
Depending on the presence of the reversing mechanism, there are tools with a switch or without it. In the former case, it is possible to change the direction of rotation, thus, allowing to tighten or loosen fasteners without any difficulties. In the latter kind of tools, the ratcheting mechanism can’t be switched and it works only when turning it anti-clockwise.
Depending on the type of the ratchet head, there can be flare nut spanners and ring spanners. The former ones can be used as an open-end head. In particular, they are used when working with fasteners of brake and fuel hoses. During the work, there is no necessity to detach and re-attach the device all the time. The latter ones have a similar operating principle as ring spanners.
Combination ratchet spanners aren’t intended for heavy duty use. For example, they aren’t suitable for loosening corroded fasteners.
You shouldn’t use damaged devices. When using extension bars or adapters, make sure they are securely fixed. If the connection is loose, it is necessary to replace the head and examine the fastener for damage.
It is necessary to use heads that fit the parts you’re going to fasten or loosen. Otherwise, there is a risk of damaging both the device and the component.
