Ko-Ken Screw/Stud Puller 1/2" Drive x 1/2" | AIMS Industrial

The Ko-Ken 1/2" screw and stud puller is designed to extract broken fasteners from engine blocks, cylinder heads, manifolds, and other critical components where a drill-out or Helicoil repair would be damaging or impractical. The A/F measurement system covers common broken fastener diameters across automotive and general engineering applications, and the 1/2" drive connection means you can apply the full torque of your existing impact wrench or ratchet to remove even seized broken studs. Japanese Ko-Ken manufacturing ensures the extraction geometry holds up under the high reversal torque needed for stud removal.
