About Norwolf™ Tool Works

Since 1995, Norwolf™ Tool Works has been at the forefront of innovation in the bolting industry, developing groundbreaking solutions that have transformed the way critical bolting applications are performed worldwide.

Our journey began with the invention of the Missing Link® Flat Torque Multiplier, the first flat torque multiplier of its kind. Today, the Missing Link has become the industry standard, trusted at wind energy sites around the world as well as across numerous industrial sectors where access to confined spaces is critical.

Building on that success, we expanded our product portfolio with innovative hydraulic bolting solutions. The TCon™ Hydraulic Bolt Tensioner was engineered to operate with any 10,000 psi hydraulic pump while fitting into the same limited spaces as competitive systems requiring 20,000 psi. The result is a faster, safer, and more efficient tensioning solution that is renowned for its exceptional durability and reliability.

Norwolf continued to redefine industry standards with the introduction of the Calibore® Bolt Calibration System. This truly universal calibration tool accurately calibrates bolts using a wide range of torque equipment, including hydraulic torque wrenches and electric torque multipliers. Its lightweight design, portability, and ease of operation make it one of the most user-friendly calibration systems available.

In 2012, responding to the demanding requirements of the rapidly growing U.S. shale oil industry, Norwolf developed the X-Driver® Hydraulic Torque Wrench System. Designed for maximum versatility and performance, the X-Driver quickly became the preferred hydraulic torque wrench throughout the major shale regions of North Dakota and South Texas. Its extensive range of interchangeable drive options enables it to handle virtually every bolting application with unmatched flexibility.

Innovation extends beyond our standard product line. Norwolf is widely recognized for designing and manufacturing custom bolting solutions tailored to unique customer requirements. Leveraging our advanced manufacturing capabilities, we can often engineer and produce specialized tools and accessories within hours, helping customers minimize downtime and maximize productivity.

In addition to manufacturing industry-leading bolting equipment, Norwolf provides comprehensive support services, including equipment calibration, rental, maintenance, and repair. Our commitment to quality, innovation, and customer service has earned the trust of clients across the wind energy, oil and gas, power generation, heavy industry, and infrastructure sectors.

For more than three decades, Norwolf™ Tool Works has remained committed to delivering safer, smarter, and more efficient bolting solutions that keep critical operations running around the world.
