Features and Benefits:
1/2" square drive, 5 piece stud puller set that includes sizes 6, 8, 10, 12, and 14mm. Stud pullers are used to drive a stud bolt that has no head or point to be grasped. Normally a stud bolt is removed after driving the nut after it is locked with a double nut. The three internal rollers work by narrowing the internal diameter created a steady hold for rotating the stud bolt. Ko-ken Stud pullers have hexagon body designs which were created to lessen the excessive load on cages and rollers inside the pullers.
