Overview

The Blue Spot Tools 4PC Nut Splitter Set tackles seized or corroded nuts from 9mm to 27mm (3/8" to 1 1/16") without damaging bolt threads. Four individual splitters cover the full range, each matched to a different nut size. The outer body is heat-treated carbon steel. The nut splitting head is chrome molybdenum, hardened to 50-55 HRC for maximum cutting strength.

Each splitter in the set uses a standard hex socket or spanner. No specialist equipment is required. This set is backed by the Blue Spot Tools Lifetime Guarantee.

What's Included

• Nut Splitter 1: 9-12mm (3/8" - 15/32")
• Nut Splitter 2: 12-16mm (15/32" - 5/8")
• Nut Splitter 3: 16-22mm (5/8" - 7/8")
• Nut Splitter 4: 22-27mm (7/8" - 1 1/16")

Key Features and Benefits

• Heat-Treated Carbon Steel Body: The outer casing withstands heavy torque application without cracking or distorting.
• Chrome Molybdenum Cutting Head: The Cr-Mo head holds its edge through corroded and toughened nuts, forcing a clean split without chipping.
• Bolt Thread Protection: The chisel drives into the nut face only, leaving the bolt thread undamaged and ready for reuse.
• Four-Size Coverage: The set spans from 9mm to 27mm (3/8" to 1 1/16"), so a single purchase handles a wide range of everyday jobs.
• Standard Socket and Spanner Compatible: Each splitter works with commonly available hex sockets and spanners - no proprietary drive required.
• Blue Spot Tools Lifetime Guarantee: This set is backed by the Blue Spot Tools Lifetime Guarantee.

Typical Applications

• Removing seized or corroded nuts from exhaust systems and brake components
• Breaking off rounded nuts that no longer grip with a spanner or socket
• Suspension and steering work where bolt threads must stay intact
• General automotive servicing on cars, vans, and light commercial vehicles
• Workshop maintenance tasks on agricultural or industrial machinery
• Removing rust-welded nuts from chassis, sub-frames, and body fixings

How to Use

• Select the Correct Splitter: Measure the nut flat-to-flat and choose the splitter that covers that size range.

• Fit the Splitter Over the Nut: Slide the ring over the nut so the chisel blade sits flat against one face.

• Attach a Socket or Spanner: Fit the correct hex socket or spanner to the drive stud at the end of the splitter.

• Apply Torque: Turn clockwise to advance the chisel blade against the nut, increasing pressure steadily until the nut cracks.

• Remove the Nut: Once split, pull the broken nut away from the bolt thread by hand.

Frequently Asked Questions (FAQs)

• Does a nut splitter damage the bolt thread?
  No. A nut splitter cuts into the nut face only. The chisel blade does not contact the bolt thread, so the thread stays intact and usable after the nut is removed.

• How do I choose the right nut splitter size?
  Measure the nut across the flats (A/F) - flat face to flat face - not the bolt diameter. Match that measurement to the size range stamped on the splitter. Using an undersized or oversized splitter can damage both the tool and the nut.

• Can a nut splitter be used on hardened or stainless steel nuts?
  A nut splitter can tackle most standard nuts, but very hard or high-tensile hardware puts extra stress on the chisel blade. Applying a small amount of cutting fluid before use reduces the force needed and helps preserve the blade.

• Should I apply penetrating oil before using a nut splitter?
  On heavily corroded or rusted nuts, soaking with penetrating oil beforehand reduces the resistance the splitter has to overcome. This improves the result and reduces the risk of overloading the tool.

• Is a nut splitter the same as a nut breaker or nutcracker?
  Yes, these are different names for the same type of tool. All three terms describe a device that uses a driven chisel blade to crack a seized nut from the bolt it sits on.
