Types of Single Stage Tensioners

  • Fixed: made for a specific stud and nut size
  • Variable: able to accommodate a number of different stud and nut sizes
  • Large stud: for applications with studs over 6” in diameter
  • High load and stroke: for applications requiring high bolt loading or an extra long stroke

 

Single Stage Tensioners

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

 

Single Stage Bolt Tensioner Options

SOLY provides a wide variety of single stage hydraulic tensioners in both fixed models used with a specific stud size, and variable models that work with a variety of stud sizes.
