230a - Stahlwille Double Ended Ring Spanner
shallow offset, SAE AS 954 (dimensions and test loads); Fed. Spec. GGG-W-636E, S.B.A.C. Techn. Spec. T.S. 48 up to size 1/2", HPQ high performance steel, chrome plated.
The problem: although there is hardly enough room to move, you still have to apply considerable torque to loosen a stubborn screw.
The consequences: many of the sockets available are useless simply because their wall thickness makes them impracticable in awkward places.
The solution: STAHLWILLE HPQ®*-sockets are manufactured from selected tough steel alloys. These sockets will not slip off the head of the screw, nor will they stretch when subjected to heavy loads. Their extremely thin walls and unbelievably high load capacity are simply exemplary. HPQ®-sockets are free of cadmium and are therefore suitable for use on titanium alloy parts and titanium fasteners as used e.g. in the aerospace industry, where safety is a crucial factor. They meet these aerospace standards: E DIN EN 3709, E DIN EN 3710, SAE AS 954-E, S.B.A.C. AS 40605/40606, MS-33787, MIL-W-8982.
