Specific tools are required for loosening and tightening bolted connections in industrial constructions, the building or (petro)chemical industry. The force with which the bolts and nuts are tightened or loosened must be exactly right. The quality and size of the bolted connection determine the max. torque, the tools should match these specifications.
Factors such as ageing and corrosion due to moist (which happens very frequently in offshore installations) or due to heat (for example plastic extrusion) sometimes make it difficult to select tools for bolted connections, because the force required for loosening is much larger in these situations than under normal circumstances.
Laco sells and rents tools for bolted connections and employs professionals, who can help you choose the tools you require for the bolted connections.
