What is the primary purpose of a spanner wrench?

• A. tightening/loosening hose couplings
• B. adjusting nozzle angle
• C. prying open doors
• D. cutting wire

Answer: (A)

The main idea is that a spanner wrench is built to grip the lugs or flats on fire hose couplings so you can tighten or loosen them without damaging the threads. This is essential in interior attack to secure a watertight connection between hose sections and keep a steady water supply as you advance lines. The tool is specifically for manipulating coupling nuts, not for adjusting the nozzle, prying doors, or cutting wire. Nozzle adjustments are made at the nozzle with its own controls, prying doors uses a halligan or similar tool, and cutting wire requires cutters or saws—none of which are the spanner wrench’s function.
