This wiki has been updated 8 times since it was first published in June of 2019. A spanner wrench is a specialty tool that is designed specifically to apply high torque to spanner head screws, bearings, and to shaft collars that are found in modern suspension components. They may come with pins on the inside or end hooks to catch the edges of shaft fasteners. Our picks cover some of the best available that will provide dependable performance.

Editor's Notes

June 28, 2019:

Spanner wrenches are a great tool to have and they perform a wide range of jobs. Many prefer them over pipe wrenches because they are often lighter and provide the same leverage in confined sink areas to tighten or loosen old pipe nuts and collars.

There are many great options for spanner wrenches available for purchase. The Armstrong 34-376, the Williams WS-474, and the Martin SHW5K represent the best available sets. They not only use high strength materials and finishes but they also make their tools a lot more usable by adding girth to their handles. This is where tools like the 1320 Performance 4PC-COR, and the JEGS 81802 fell short. They are both well-built for the jobs they are meant to perform but they would be much better if their handles were dipped in rubber. Part of the reason why they have such a thin profile is because they appear to be laser cut, which makes it impossible to give a proper profile. Again, a simple rubber dip would have been acceptable.

Working with spanner wrenches normally involves manipulating high pressure systems like coil-overs or fluid conduits like piping. Any work on these systems should only be performed by trained professionals to avoid personal injury or damage to property.
