Kukko stud and screw extractors, internal-toothed or grooved, left-hand

Kukko stud extractors remove broken or seized studs and bolts that no longer have a head to turn. In engine maintenance, machine building and repair shops, this is the tool to get a threaded stud out without damaging the tapped hole.

There are two main types. Extractors with internal teeth grip the stud all round and cover 5 to 10 mm, 8 to 19 mm or 18 to 25 mm; a version with an extra-large tensioning range takes 5 to 19 mm in one tool. The finely grooved, left-hand series bites harder the more torque you apply. It runs in steps from 3 to 52 mm, so you can pick the right size for every diameter. For bolts in tight spaces there is a bolt remover of Ø 30 mm.

Measure the stud diameter and take the smallest range that covers it, for the best grip. These extractors belong to Kukko cutting tools, together with the brand's other machining tools.
