The long impact sockets are made of CrMo SCM-440 chromium molybdenum steel, which guarantees a long service life when working at cycles of about 5000 strokes per minute.

• CrMo SCM-440 steel is a unique alloy steel, which has 2 times higher tensile strength than ordinary carbon steel and 3 times higher yield strength, these features make Yato sockets maintain their nominal size for a long time and do not crack under impact work.
• the sockets are equipped with AS-DRIVE system preventing destruction of nuts and their blocking
