Coatings Options for Hydraulic Nuts

Coatings Options for Hydraulic Nuts

Hydraulic tensioning with hydraulic tensioners and nuts is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical fasteners. At HTI, we’ve been building hydraulic tensioners and nuts since 1986. 

Our engineers are happy to consult with you to help choose the right finish for your hydraulic nuts

The standard coating for hydraulic tensioners and nuts is a hot black oxide (on 4140 alloy steel).

The following additional coating options are available:

  • Xylan coating for corrosion resistance and low friction
  • Anodizing on aluminum products
  • Nitriding on 17-4 stainless steel for surface hardness and galling resistance
  • Hot dip galvanizing
  • Black phosphate for corrosion resistance

Custom Engineered Solutions Since 1986

HTI has been designing engineered solutions to your toughest bolt tensioning problems for over 35 years! Choose from one of HTI’s hydraulic nut catalog models or we can design a custom hydraulic nut for any application when a standard model won’t work. HTI hydraulic nuts can be designed for imperial or metric-sized studs. Contact us to start the process of getting the right tensioning solution for your application.
