Screw and Stud Pullers
Hexagon body design can lessen the excessive load on cages and rollers inside the pullers.

4100A-5/8 is designed not to have 1/2” Sq. drive.

Repair Kit: 4100ARK-5/8

A stud bolt could not pass through 4100A-5/8 if it had the 1/2” Sq. drive, since 5/8" stud bolt is bigger than 1/2” Sq. drive.

As it mentions on our catalogue, please drive the outer hexagon part with 27mm socket or ring wrenches.
