Complementary bolting solutions

In addition to its comprehensive range of bolt tensioners, Hytec SA sources, stocks and supplies additional bolting solutions. These are:

  • Nut Splitters: 2 variations in this range. The hydraulic nut splitter with a 15 & 25-ton model that reduces the risk of bolt damage via a unique dial-in feature; and the ENS hydraulic nut splitter with a triple-edged replaceable cutting blade.
  • Torque Wrenches: this range of hydraulic torque wrenches is made up of low clearance, square drive and high cycle torque wrenches. Low clearance models have a long neck and small radius that allows for bolt fastening and torqueing in difficult-to-access areas. The high cycle variant caters for up to 50 000 operating cycles and the square drive version enables faster, high-strength torqueing.
  • Torque Wrench Pumps: electrically powered torque wrench pumps and torque wrench pumps for air make up this range. The former can be used on single- and double-acting tools and the latter has the advantage of air as a power source.
