Pretty much anyone and everyone. Open-end wrenches are used to tighten nuts and bolts, which can be found on tires, furniture, vehicles, and almost any machinery. Because of this, it is so generic that it is used by everyone. What materials can they be used on? Nuts and bolts, which are typically made out of steel. How is it used? You slide the wrench into the nut/bolt so it fits perfectly, then begin to turn to either loosen or tighten. What are their distinctive features? As the name implies, it is open-ended, meaning it doesn’t have a closed shape. It is able to slide onto a nut from the side, rather than from the top. Where can I buy it? Any home improvement or hardware store. How much does it cost? It varies, depending on size. ¾-inch wrenches can cost as low as $5 dollars. Higher-end wrenches, some 1-inch wides, can cost an upwards of $30. But the average price is no more than $10-$15. |
