STT Premium impact sockets in case – 17, 19, 21 mm
Mounting square 1/2"
The STT sockets can be used with air spanners (also impact spanners), geared spanners and other spanners with a shank size of 1/2" (fits among others the Stix STT series impact spanners). The specially shaped part connecting the sockets to the spanner stem makes it easier to change the sockets and reduces wear on the handle. The sockets can be locked onto the spanner with a ball catch or with a pin and ring (depending on the design of the spanner).
High-strength CR-MO steel
The sockets are made from a special variety of chrome-molybdenum steel, used in the manufacture of top-quality drill bits and spanners. The use of chromium and molybdenum as alloying additives increases the steel's resistance to impact and wear, as well as to high temperatures and the effects of corrosion.
Ideal for unscrewing wheels
The set includes 3 sockets in metric sizes: 17, 19 and 21 mm. This is the perfect set for wheel service work - it corresponds to the most common bolt and nut head sizes used to fix rims on cars.
Comfortable to work with
The socket length of 78 mm and thin walls (approx. 4 mm) make it easier to reach screws that are difficult to access. The hexagonal, convex profile of the socket has been specially shaped to reduce the risk of skipping on rounded heads. The design of the socket ensures optimum force and reduces vibration levels during use.
Clear marking
The sockets are permanently marked - the size of each socket has been laser engraved. In addition, they are marked with part numbers and the manufacturer's logo.
Practical case
The sockets are housed in a plastic case for easy transport and storage.
