HYTORC’s Bolting Products

HYTORC, the world's oldest and largest manufacturer of industrial bolting systems, has a unique combination of industrial bolting tools and fasteners that will help nuclear industry end users save time, save money and improve safety. When combined, the HYTORC jGUN, HYTORC Nut, and HYTORC Washer provide an innovative solution that can improve efficiency on all bolting jobs.

HYTORC's innovations for industrial bolting eliminate dangerous pinch points and allow for hands-free operation to keep tool operators at a safe distance from the job. For the first time, turbine casings and couplings can be assembled and disassembled without damaging bolts and with industry-leading bolt load accuracy to eliminate unintentional nut loosening and joint failure. Ultimately, this technology provides dramatic improvements to safety and productivity in an industry.

jGUN

The jGUN is an air-powered torque multiplier available in both dual speed and single speed varieties. Both have adjustable torque outputs and provide an even and accurate bolt load every time. When used with the HYTORC Washer, the jGUN provides the highest bolt load accuracy of any comparable bolting system.

The dual speed guns add a high-speed rundown mode that eliminates the need for impact guns, which are traditionally used for pre-torquing. The jGUN uses precision gearing to produce constant, calibrated power without the noise or vibration – A first in the industry!

The HYTORC Nut

The HYTORC Nut is the only fastener that adds safety, speed and accuracy to any bolting job. This patented system is calibrated to achieve and maintain the desired bolt load every time. It can be operated hands-free, even on inverted applications. Additionally, this system eliminates the risk of damaging bolt threads – even during removal after long durations at high temperature.

Unlike traditional fasteners, the HYTORC Nut does not turn on the bolt threads. This three-piece system uses a washer, an inner sleeve and an outer sleeve to eliminate unknown variations in friction and provide a straight pulling force on the bolt, which is locked in place when the desired load is reached. Unlike hydraulic puller-style tensioners, the HYTORC Nut never goes beyond desired load, eliminating the chance for bolt yielding and reducing operating pressure by 66 percent.

HYTORC Washer

The HYTORC Washer is the simplest way to add efficiency on all bolting jobs while increasing the lifespan of tools. At nearly the same cost of a standard washer, the HYTORC Washer changes everything about industrial bolting. In the past, all bolting systems required reaction fixtures to stop the tool from turning; these fixtures created dangerous pinch points and added complexity to bolting jobs. The HYTORC washer eliminates reaction fixtures, making industrial bolting safer, faster and more intuitive. Additionally, this system prevents unintentional nut loosening and ensures even and accurate bolt load every time. Using the HYTORC Washer also removes internal pressure from hydraulic torque wrenches, which increases the lifetime of the tooling.
