Ball joint, 1/2'' impact. Made of the unique CrMo alloy steel SCM-440, which has twice the tensile strength of ordinary carbon steel and three times the yield strength. Thanks to the steel used, the caps do not break under the influence of impact work and retain their nominal size for a longer period.
