Set of long STT impact sockets in case 17, 19, 21 mm

Mounting square 1/2"

STT sockets can be used with air wrenches (including impact wrenches), gear wrenches and other wrenches with 1/2" shank size (they fit Stix STT series wrenches, among others). The specially shaped part connecting the sockets to the wrench stem makes it easier to replace them and reduces wear on the handle. The sockets can be locked on the wrench with a ball catch or with a pin and ring (depending on the design of the wrench).

Durable CR-V steel

The sockets are made of a special variety of chrome vanadium steel, used in the production of top-quality drills and wrenches. The use of chromium and vanadium as alloying additives increases the hardenability of the steel and provides high resistance to corrosion and abrasion.

Ideal for wheels

The set includes 3 sockets in metric sizes: 17, 19 and 21 mm. This is a perfect set for wheel service work - it corresponds to the most common sizes of bolt and nut heads used for fixing rims on passenger cars.

Comfortable to work with

The sockets' length of 78 mm and thin walls (about 4 mm at the thickest point) make it easier to access deeply embedded fasteners. The hexagonal, convex profile of the sockets has been specially shaped to reduce the risk of skipping on rounded heads. The design of the sockets ensures optimal force and reduces vibration levels during operation.

Clear marking

The sockets are permanently marked - the size of each socket has been laser engraved. In addition, catalog numbers and the manufacturer's logo have been applied to them.

Practical carrying case

The sockets are placed in a plastic case - a case that facilitates transport and storage of the sockets.
