"The 3-piece Einhell car impact socket set, ideal for gentle wheel changes, contains impact-resistant sockets in the common sizes 17, 19 and 21 mm. Made from durable manganese-phosphatised CrMo steel, they are perfect for high torques. A protective plastic sleeve protects the rims from scratches, especially on painted and polished alloy rims. The colour coding in red, blue and yellow enables quick identification of the spanner sizes. The set is supplied in an M-CASE with EVA inlay in carbon design for clear storage without additional packaging waste. The sockets fit standard ratchets and impact wrenches with a 1/2"" square drive."
