Industries such as mining, shipbuilding, and power generation have particular requirements for extremely large nut and bolt fasteners. These pose huge difficulties with applying specified bolt tensions because, for example, a nut weighing thirty kilograms is not going to be tightened with hand tools. These are installed or removed with sledgehammers, stud heaters, or torque wrenches, which might weigh as much as the person using them. Installation of such large fasteners is extremely time-consuming, can be hazardous to workers, and frequently may not result in even tightening of every fastener to the precise tension required for long and safe joint life. Disassembly for maintenance can be equally slow, hazardous, and damaging to equipment and production schedules. A proven best-practice solution is the use of the Technofast EziTite® family of hydraulic fasteners, which are proven in service to tension large bolts. Assembly and removal times are some 15-20 times faster than conventional means, while also cutting downtime and enhancing safety and joint precision. The fasteners are so efficient and swift in operation – including operating in hazardous, hot, underground, and confined spaces –…
