Have you ever heard of a spanner? It's a tool used to hold two objects in tension. It can be used in a variety of ways, from tightening screws to adjusting bike brakes. It's an incredibly versatile tool, and it's essential to have one in your toolbox! A spanner is made up of two pieces: the body, which is usually metal, and the tip, which is usually made of a hard plastic material. The tip is designed to fit into the grooves of whatever object you're working on. When you turn the spanner, it adjusts the tension between the two pieces, allowing you to make precise adjustments. Whether you're a professional mechanic or a hobbyist DIY-er, you should have a spanner in your toolbox!
