Crafted from 304 stainless steel (via casting and heat treatment processes) for superior hardness and impact resistance. It resists rust in damp or outdoor settings, ensuring reliable long-term performance. 3-in-1 Design: A versatile tool that saves time and effort. It addresses three common needs: a large pentagonal end (fits 1-1/16"" / 1.5"" Od maintenance bolts), a standard pentagonal end (fits 7/8"" / 1.26"" Od bolts), and a valve end (1.38"" x 0.75"", suitable for water meters or shut-off valves). Eliminates the need to carry multiple tools. Includes Carabiner: Prevents loss and ensures easy access.
