Nut Splitters Essential for Protecting Joint Integrity

Rusted tight? Stripped edges? Corroded Nuts?

 

 

 Nut Splitters protect your hydraulic precision wrenches from premature wear, safeguard flanges from expensive damage, reduce injury risks for personnel, and cut down on costly job delays. 

 

Finding The Right Nut Splitter

Selecting the right nut splitter depends on your application and nut size. Here’s what to consider:

  • Flat Surface or Flange Joint: For flat surfaces like railroad bolts or other challenging jobs, an Angle Head Nut Splitter is often the best choice.
  • Nut Size: Measure across the flats—point to point, not side to side—to ensure the correct fit.
  • Nut Type: Identify whether you’re dealing with Heavy Hex, Round, Lock Nut, or another variation to choose the appropriate splitter.
 

This ensures efficient cutting and minimizes tool wear.
