Types in this collection
- Chrome-plated adjustable spanners, in various lengths

- Roller-type wrenches, with a worm screw to adjust the opening
- Narrow-jaw adjustable spanners

How to choose
The length of the spanner also indicates the maximum opening and the leverage available: small sizes are for precision work, large ones for big nuts. It is always best to tighten the spanner so that the force is applied to the fixed jaw and not to the movable one.

Frequently asked questions: Adjustable Spanners
What is an adjustable spanner used for?
The adjustable spanner, also called an adjustable wrench, has a movable jaw that adapts to nuts and bolts of different sizes. A single spanner replaces a set of fixed spanners, which is useful in maintenance, in plumbing and when fitting pipes and fittings. It is a tool to keep in the toolbox at all times for quick jobs.
What length of adjustable spanner should I choose?
The length determines how much leverage you can apply: the bi-material spanners of 150, 200, 250 and 300 mm cover light and medium work. Tightening large bolts calls for longer spanners. Choose a size that lets you apply force without straining your wrist.
Thumbwheel or chrome-plated adjustable spanner: what is the difference?
The thumbwheel spanner has a worm screw that sets the jaw opening, so it can be closed precisely with one hand. Chrome-plated adjustable spanners, such as the Fervi models, are a classic for general work. The choice depends on how often you use it and the precision you need on the nut.
Which brands of adjustable spanners are there?
In the collection you will find adjustable spanners from Stanley, Fervi, Milwaukee, Unifix and Ingco. Stanley offers bi-material and thumbwheel models in several sizes, while Fervi offers the chrome-plated ones. Compare length, material and jaw type on the product page before choosing.
How do I use an adjustable spanner safely?
Position the spanner so that the force pushes on the fixed jaw, and check that it is firmly seated on the nut, with no play. Do not extend the lever with pipes and do not use it as a hammer, because the jaw could break or slip. A stable grip reduces the risk of scraping your hands.
How do I clean and store an adjustable spanner?
After use, wipe the spanner clean of oil and dirt and lightly lubricate the thumbwheel screw, so the adjustment stays smooth. Store it in the toolbox or hung up, away from damp, to prevent rust on the chrome-plated parts. Phosphated spanners, such as the Unifix series, should be dried thoroughly before being put away.
Which adjustable spanners are needed for plumbing?
For plumbing, medium-length thumbwheel spanners are often used, as they can grip fittings and pipes with a stable hold. Narrow-jaw spanners fit where the space around the fitting is limited. Choose the size according to the diameter of the fitting and the distance from which you have to work.
