The hexagon bolt designates a consolidated automotive hexagon head bolt and close the body toleranced regular semi-finished bolt.

The hexagon cassette hydraulic torque wrench is designed to provide easy access to maintenance and fabrication bolting tasks, plus a good torque-to-weight ratio for loosening and tightening jobs. The unibody design has an integrated support arm and few moving parts for low maintenance and is constructed from corrosion-resistant materials. They are more precise, lighter weight and easier to use in tight spaces than the flogging /impact wrenches typically used in the pipeline industry. They offer high repeatability of ±3% accuracy. The tool also features high pressure (800 bar) double-acting hydraulic operation, which increases tool portability while reducing cycle times and the need for manual labour.

Hexagon Head Steel Wrench is a T-type socket wrench having three hexagonal rods on three ends of a Y-shaped handle, and three double-head hexagon sockets of successive hexagonal holes mounted on the three hexagonal rods and stopped at respective first positions by respective first steel balls for turning hexagon head screws. Each double-head hexagon socket is moved inwards on the respective hexagonal rod and stopped at a respective second position by a respective second steel ball permitting a hexagon bit of different size on the respective hexagonal rod to project out of the respective double-head hexagon socket for turning a socket head screw.
