Split seized nuts cleanly with Kukko 55-3

Practical benefits

Safe splitting without thread damage: You effortlessly split rusted or seized nuts from 27 to 36 mm without damaging the underlying bolt thread.
Hardened chisel for tough nuts: The hardened cutting chisel reliably penetrates class 6 to 8 steel nuts during heavy-duty maintenance tasks.
Easy chisel retraction mechanism: You quickly wind back the cutting blade after each operation for fast and continuous mechanical work.

In a nutshell

The right choise for

With the Kukko 55-3 single-edged mechanical nut splitter, you remove rusted, seized, or rounded nuts quickly and safely. Engineered for nuts with a width across flats of 27 to 36 mm, this tool eliminates the need for angle grinders or cutting torches. Tightening the spindle forces the hardened chisel directly into the stuck nut, splitting it cleanly without damaging the underlying bolt thread. Its compact length of 125 mm allows you to work comfortably in confined spaces, while the chisel retracts smoothly after each operation.

55-3-M:Spare chisel for single-speed mechanical nut splitters 55-3-C, K-55-B, 55-3

Product description

Single-sided, mechanical nut splitters are used for splitting seized, rusted or over-turned nuts up to a tensile strength of 800 N/mm2. In this splitting process, the threaded end remains undamaged. The faceted sharp cut of the chisel penetrates deep into the nut when tightening the spindle until it is split. In restricted environmental conditions, when only limited space is available around the nut, the single-sided nut splitter is exactly the right choice.

Application

For loosening stuck, rusted or crazy nuts with a tensile strength of up to 800 N/mm².
