What is a Spanner Wrench?
A spanner wrench, often simply called a spanner, is a type of wrench with a fixed or adjustable head designed to grip and turn fasteners like nuts and bolts.
Unlike a standard wrench, which grips flat sides, a spanner wrench typically engages with the fastener’s notches or pins, making it particularly useful for more specialized tasks.
Common Uses of a Spanner Wrench
Spanner wrenches are versatile and can be used in a variety of situations.
Whether you’re tightening a bolt on a piece of furniture or loosening a stubborn nut on a plumbing fixture, a spanner wrench is the tool for the job. Some of the most common uses include:
- Tightening and Loosening Nuts and Bolts: The most straightforward use of a spanner wrench is in tightening or loosening nuts and bolts where a regular wrench might slip.
- Working with Pipes: Plumbers often use spanner wrenches to grip and turn pipes without damaging them.
- Automotive Repairs: A spanner wrench is invaluable in automotive work, from adjusting coilovers to maintaining the engine.

What is a Spanner Wrench Used For in Automotive?
In the automotive world, a spanner wrench is a staple in any mechanic’s toolbox. It’s particularly useful for tasks that require precise adjustments.
For instance, when working with coilovers (a type of suspension system), a coilover spanner wrench is essential. This specialized wrench helps adjust the height and tension of the coilover springs, which directly affects the vehicle’s handling and ride comfort.
Beyond coilovers, spanner wrenches are also used for tightening or loosening parts in the engine bay, exhaust system, and other components where space might be tight, and a traditional wrench won’t fit.
For automotive enthusiasts, having a Coilover Spanner Wrench in your toolkit can make adjustments to your suspension a breeze.
