Specifications: Common specifications for adjustable wrenches include 150mm×19mm, 200mm×24mm, 250mm×30mm, 300mm×36mm, etc. Dimensions: Adjustable wrenches come in 9 sizes: 100, 150, 200, 250, 300, 375, 450, 600, and 650. The optimal opening size can be calculated by dividing the above specifications by 10. Structure: An adjustable wrench consists of a head and a handle. The head is composed of a movable jaw, a fixed jaw, a wrench opening, a worm gear, and a pin. Adjustable Wrench: Commonly known as a crescent wrench, its opening width can be adjusted within a certain range, making it a tool used for tightening and loosening nuts and bolts of different specifications.
I often tinker with cars in the garage and find that adjustable wrenches are indeed super practical. Their common models are categorized by wrench length, such as 6-inch, 8-inch, or 10-inch, which refers to the overall size. In terms of specifications, each wrench has a maximum opening width. For example, a 6-inch wrench typically has a maximum opening of around 20 mm, suitable for small bolts; an 8-inch one is about 25 mm, ideal for medium-sized nuts; and a 10-inch might go beyond 30 mm, perfect for large bolts. As for material, it's best to choose chrome-vanadium steel—durable and less prone to stripping. Personally, I prefer the 8-inch wrench for its flexibility; it's handy for changing tires or fixing engines. Remember not to go too big, as oversized wrenches can be hard to grip and may cause hand injuries. It's advisable to regularly check your wrenches for wear to avoid accidents from slipping.
