Nut Splitters are used to remove nuts that are seized, corroded or have become damaged, preventing their removal by traditional methods.
A hydraulic piston in the body of the nut splitter pushes a chisel-type cutting blade into the flat of the nut with sufficient force to crack the nut – the tool is then rotated 180 degrees and the process is repeated. The nut can then be removed in two halves.
It is critical that the correct size of nut splitter is used for the nut that is to be split.
The HNS nut splitters are named by the across flats size of the applicable nut in mm:
HNS1924 – AF nut size 19 to 24 mm. (M12 to M16 Thread – 19 to 24 AFmm)
HNS2432 – AF nut size 24 to 32 mm. (M18 to M22 Thread – 27 to 32 AFmm)
HNS3241 – AF nut size 32 to 41 mm. (M24 to M27 Thread – 36 to 41 AFmm)
HNS4150 – AF nut size 41 to 50 mm. (M30 to M33 Thread – 45 to 50 AFmm)
HNS5060 – AF nut size 50 to 60 mm. (M36 to M39 Thread – 55 to 60 AFmm)
HNS6075 – AF nut size 60 to 75 mm. (M42 to M48 Thread – 65 to 75 AFmm)

HNS – Angled Head Hydraulic Nut Splitter Tool Kit
The RenQuip HNS range of nut splitters are designed with an angled head. This allows the Nut splitters to access nuts that are located flush against a surface.
The HNS range are actuated by single acting spring return hydraulics and can be powered by any of the PHS range of hand pumps.
Care should be taken when using the tools to ensure the nut splitter is centralised and perpendicular to the flat of the nut being split. The cutting blade should be greased prior to each cut to increase the life of the blade.
The following application chart helps identify the appropriate nut splitter.
