Product Information

Full details

This BlueSpot Tools 2-Piece Nut Splitter Set is designed for mechanics and engineers tackling stubborn or corroded nuts. Its primary benefit is providing a durable and effective solution for removing seized fasteners without damaging the surrounding components. A potential caveat is its size limitation, with the larger splitter only accommodating nuts up to 22mm (7/8”). This set features heat-treated carbon steel construction for the casing and hardened chrome molybdenum splitting heads, ensuring longevity and robust performance for maintenance and repair tasks.

FAQs

What is the maximum nut size this set can handle?

The larger nut splitter in this set can handle nuts up to 22mm (approximately 7/8”). The smaller splitter is designed for nuts between 12mm and 16mm.

Do I need any other tools to use these nut splitters?

Yes, you will need a suitable hex socket or spanner to turn the screw mechanism on the nut splitter. The set is designed to work with 14mm sockets/spanners for the smaller splitter and 19mm for the larger one.

How do I prevent rust on the nut splitters?

After each use, clean the tools and apply a light coating of machine oil, particularly to the carbon steel casing and the splitting head, to protect them. Store them in a dry place.

Can these nut splitters be used on bolts as well as nuts?

These tools are specifically designed for splitting nuts. While they might inadvertently damage a bolt during the process of splitting a nut, they are not intended for cutting bolts.

What is the material of the splitting head?

The splitting heads are made from hardened chrome molybdenum, which provides durability and wear resistance.

Are these tools suitable for professional mechanics?

Yes, they are manufactured from heat-treated carbon steel with hardened chrome molybdenum heads, making them suitable for heavy-duty use by professional mechanics and engineers dealing with stubborn fasteners.

What is the hardness rating of the splitting head?

The splitting heads have a hardness rating of 50-55 HRC, indicating their strength and ability to withstand significant force.

Troubleshooting

Nut splitter not splitting the nut

Ensure the splitter is correctly positioned over the nut and the cutting edge is firmly against the nut's side. Check if the nut size is within the tool's range (12-16mm or 16-22mm). Apply more force by tightening the screw mechanism with a suitable wrench. For extremely seized nuts, try tapping the body of the splitter gently with a hammer after tightening to help break the bond.

Splitting head appears to be wearing down quickly

Verify that the nut material is not significantly harder than the tool's specifications. Avoid forcing the tool on nuts that are too large or too small for its designated range. Ensure the nut is clean to prevent grit from accelerating wear. If the head is significantly damaged, it may be time to replace the tool.

Screw mechanism becomes stiff or difficult to turn

Clean the screw threads thoroughly to remove any debris or rust. Apply a penetrating lubricant or light machine oil to the threads and work the mechanism back and forth. Ensure the tool is not bent or damaged, which could cause binding.

Tool shows signs of rust

Clean the rusted area with a wire brush. Apply a rust inhibitor or a light coat of machine oil to protect the metal surfaces, especially the carbon steel casing. Store the tool in a dry environment.

Pros and Cons

Pros

  • Constructed with durable, heat-treated carbon steel and chrome molybdenum for longevity.
  • Effectively splits seized or damaged nuts, preventing thread damage.
  • Includes two sizes (12-16mm and 16-22mm) to cover a range of common fasteners.
  • Designed for heavy-duty use in professional or demanding DIY environments.
  • Offers good wear resistance due to hardened splitting heads.

Cons

  • Maximum nut size is limited to 22mm (7/8”), not suitable for larger fasteners.
  • Requires significant force and potentially a wrench or socket to operate, which is not included.
  • May not be effective on exceptionally hardened or specially treated nuts.
  • Potential for the tool to slip if not properly seated on the nut.
  • Requires regular maintenance (cleaning and light oiling) to prevent rust on carbon steel components.

Setup, Compatibility & Care

Setup: No assembly is required. The nut splitters are ready for immediate use. Ensure the nut to be split is clean and free from excessive debris.

Compatibility:

  • 12-16mm Splitter: Fits nuts between 12mm and 16mm. It is designed to work with 14mm hex sockets and spanners.
  • 16-22mm Splitter: Fits nuts between 16mm and 22mm (7/8”). It is designed to work with 19mm hex sockets and spanners.

Care:

  • Cleaning: After each use, clean the nut splitter with a dry cloth to remove any dirt, grease, or metal shavings.
  • Lubrication: Apply a light coating of machine oil to the screw threads and splitting head to prevent rust, especially the carbon steel components, and ensure smooth operation.
  • Storage: Store the nut splitters in a dry environment, preferably in their original packaging or a tool organizer, to protect them from moisture and damage. Avoid storing them in damp conditions.
