This Stahlwille spline drive combination spanner is for use with 3/8” fasteners and size 12 splines. It has slim heads and the ring end of the spanner has an angle of 15°, both of which allow for work in confined spaces.
This tool features an AS-Drive profile which enables high force transmission without damaging the fasteners. Stahlwille spanners are reinforced at the point between the jaw and the shank which makes the load zones more resilient and reduces the risk of breakage to an absolute minimum.
It is comfortable for the operator to use thanks to its non-slip finish which means it fits comfortably in the hand, even when used for long periods of time and when high forces are applied.
The thumb groove along the handle of the spanner eliminates material where there is no stress and concentrates it where it is needed most. This allows for extreme load bearing capacities and maximum flexural strength thanks to the lower weight.
