Adjustable spanner selection for repairs and DIY tasks. They can be used for a wide range of fasteners, meaning that you need only one tool to undertake lots of different jobs. You can get a small adjustable spanner and it will be easily stored and very handy to have. An adjustable wrench has a moveable jaw which allows you to open it wide for large bolts or narrow it down for smaller ones. They are useful tools to have around but it's important to take care to size the spanner correctly when using it to avoid damaging the nut or bolt you are trying to move. If it is too large the spanner could damage the shape of the fastener, making it difficult to remove or fasten in the future.Choose from a range of sizes and styles to suit - you could get one with a cushioned grip for comfortable usage or a simple carbon steel wrench - whichever you prefer.
