Stahlwille 58211008 Open-End Insert Tool 731/10, 8 mm — BOLTON SKU 52465.
About the Stahlwille 58211008 Open-End Insert Tool Technical
The Stahlwille 58211008 Open-End technical component is the 8 mm member of the 731/10 open-end insert tool series, supplied under STAHLWILLE order number 58211008, and it is fitted into a compatible torque wrench head rather than used as a standalone spanner. The 8 mm jaw sits one step above the smallest instrumentation sizes in the series and is a common across-flats dimension on small tube couplings, threaded adaptors and terminal hardware. Because the jaw is open on one side, it can be slid laterally onto an 8 mm hexagon that already has a tube, cable or shaft running behind it, so the specified torque can still be applied without breaking the line or stripping the assembly back to gain access. Ordering the 8 mm insert alongside the adjacent sizes keeps one torque wrench usable across a whole fitting range. Insert mount dimensions, effective length, the maximum torque permitted through the insert and the wrenches it fits are confirmed against STAHLWILLE’s current catalogue data at quotation.

Typical applications
An 8 mm open-end insert is used to torque small tube unions, adaptors and bulkhead nuts on hydraulic, pneumatic and fuel-system runs, and to tighten 8 mm terminal and stud hardware where a socket cannot be seated squarely. It is a routine size on ground-support rigs and test benches, where fittings are made and broken repeatedly and every remake has to be brought back to the same stated value rather than nipped up by hand.
