1/2 inch Drive Impact Socket Set, 3 Pc, 17 mm - 21 mm

Sturdy shape especially for use with electric or compressed air impact wrenches. With cross hole and snap ring groove for securing sockets. Internal square to DIN 3121. For safety reasons must always be secured using a suitable locking pin and O-ring. When changing wheels and tyres, it is important that the nuts or screws are tightened correctly in order to ensure safe driving. You can use a hex socket with plastic sleeve to ensure that the nuts or screws are tight enough, without damaging the rims. The socket is also suitable for impact wrenches. The plastic sleeve protects the rims and prevents scratches or other damage that may be caused by the tool. You can therefore be sure that your vehicle is always in top condition. The socket is an important part of any garage. Whether you are working on your vehicle yourself or are having your wheels and tyres replaced by a specialist, make sure you have this tool on hand. Advantage: The surface drive profile grips the bolt on the faces and protects the weaker corners. This reliably prevents the socket jamming or damaging the bolt heads. Application: To protect light metal bodies / rims during assembly. Reliable protection due to projecting impact resistant plastic casing. Quick differentiation of the sockets due to color coding. Material: Chromium-molybdenum steel, manganese phosphated. Content: 1 each socket No. 651220: Size 17, 19, 21 Square drive: 1/2 in
