What is a spanner wrench? What's different?

Wrench is a common hand tool used every day. This tool is commonly used to hold and rotate nuts, bolts and threaded components. Wrench is usually made of super-hard chrome-plated steel that is resistant to rust, curved and does not break when subjected to a large impact force. The body of the wrench is exceptionally long and very sturdy, helping you to avoid slipping out of the tool's hand while working.
