Bolttech Mannings helped pioneer the industrial bolting services industry. Serving customers in the oil and gas refining, chemical processing, power and pipeline industries, Bolttech Mannings grew by earning a reputation for solving problems with innovative solutions. By 1991, unable to find tools capable of meeting the durability and safety requirements that our own technicians needed, we started to manufacture hydraulic torque and tensioning systems to be used in our service fleet. Customers recognizing the superior quality of our tools demanded we make them available to them. Thirty-five years and thousands of service and research hours later we have grown into a fully integrated service and products company with state-of-the-art manufacturing facilities, a full-time staff of engineers and a culture with a passion for solving problems.
