IMPACT inserts and adaptors from STAHLWILLE offer you maximum performance. All IMPACT screwdriver sockets and IMPACT socket heads are characterised by particularly thin walls and an absolutely precise fit. This is how the IMPACT sockets and socket heads guarantee excellent power transmission as well as extremely precise work. Made of durable and long-lasting Chrome Alloy Steel and with a gunmetal finish, they also impress with their long service life and are ideal for working with powered tools, such as power screwdrivers. Many parts of the IMPACT programme are also available in practical sets, including a robust storage and transport box, or in tool mats or inserts with the Tool Control System.
