Adjustable spanners are highly versatile and able to tackle various types of fasteners of different sizes. As such, they are a mainstay in any profession that requires the tightening and loosening of bolts and pipe fittings. For plumbing, maintenance, machine repairs and adjustment, professionals and enthusiasts alike will always keep an adjustable spanner at hand.

What are the advantages of an adjustable spanner over a spanner set?

In short, convenience. A precision spanner set will usually provide you with a more accurate fit, as it matches a spanner size directly to a corresponding nut or bolt. However, if the size of the fittings and fasteners are uncertain, an adjustable wrench is adaptable, portable and versatile. Why take an entire set when one tool will do?


RS PRO aims to be your go-to brand when you need quality, reliability and value for money. With all our parts subjected to rigorous testing by our in-house experts, we're confident we can supply you with the tools and parts you need for any purpose.

When it comes to tools, RS PRO is there to support you every step of the way, no matter how ambitious your project or installation.
