The cropped blank is heated in a furnace to the correct forging temperature and then drop forged in this hot state using high press forces. Following this, the flash is then removed using flash-removal presses.

In the next step, the hole at the ring-end of the double open ended spanner 100 is punched. The subsequent grinding process ensures the tool has a smooth outside surface. Any sharp edges and flash still remaining are then removed by vibro-deburring. The purpose of the broaching operation is to ensure the ring and jaw ends have exactly the right dimensions.

The individual marking that identifies our spanners around the world is added during the profile punching operation. This special heat treatment ensures our spanners enjoy the longest possible service lifetimes. Double open ended spanner 100’s tensile strength is provided by precise hardening and the high level of ductility by the tempering process.

To make sure the spanner has a matt, non-slip surface, we sand-blast it. The jaw-end is then also polished to give it a smooth finish.Finally, the spanner is nickel-plated and chrome-plated in an electroplating process. The final product now boasts effective surface protection and a specially high-grade appearance. Typically ELORA.
