Keeping things tight to keep your turbines spinning

Your turbines are engineered to generate clean power day in, day out for decades. Your bolts hold it all together. You need to be sure they are properly tensioned the first time around, and be able to inspect them to be sure they stay that way.

TurnaSure offers a full line of DTIs for wind turbines, from blade bolts, to anchor bolts for the foundation, to tower bolts, nacelle and gearbox bolts. Every bolt in the system must be properly tensioned to ensure the integrity of the entire system. Turnasure DTIs ensure the every bolt is properly installed to its engineered required tension.

Our product line covers all metric sizes from M8 through M64 and inch sizes 1/2” through 3”. TurnaSure DTIs are available to the following National Standards:

  • ASTM F959
  • ASTM 959M
  • ASTM F2437
  • BS 7644
  • CEN 14399-9
  • Custom DTIs are also available upon request.
