Stahlwille Open Ring Insert Tool, 21mm, 9 x 12mm – ST 58231021

An Open Ring Insert Tool is an interchangeable tool head that combines the characteristics of a ring spanner with the flexibility of an insert tool system. It is designed to attach to a compatible handle or torque wrench, allowing for precise application of torque. The tool features a ring-shaped end with a small opening, which enables it to slip around a nut or bolt and engage all sides of the fastener, providing a more secure grip than an open-ended spanner.
