Description
Heavy Duty Nut Splitters, Nut Removal Tool and Automotive Repair Tool for Rusted Nuts
-
Rusted nuts finally let go: forged alloy steel with heat treatment is not easy to deform after repeated use
-
Bolt threads stay undamaged: the nut splits without damaging the bolt threads, which cuts later maintenance costs
-
Works without power: among hand tools, this one applies pressure by manual rotation, so it suits outdoor or power-free jobs
-
The right size for small nuts: a 0.4-0.5 in size range avoids tool damage or failed jobs from using the wrong size
-
Ready for real repair jobs: suited to rusted, damaged and corroded nuts on automotive chassis, pipe joints and agricultural machinery
A rusted nut on a car chassis, a pipe joint or farm machinery can stall a whole repair. Turn this nut splitter by hand, outdoors or wherever there is no power, and the nut gives way without damage to the bolt threads, so you are not paying for thread repairs afterward.

The tool is forged from 40cr alloy steel and heat treated to HRC52-55 hardness, so it is not easy to deform after repeated use. Manual rotation applies the pressure that splits the nut, and the 0.4-0.5 in (9-12mm) size range is designed for small-sized nuts. Used as a manual nut splitter alongside other car repair tools, it is a heavy duty piece of mechanic tools for rusted, damaged and corroded nuts. Wear eye protection and gloves when you split a nut, and keep your hands clear of the working end.
