Superbolt - Multi-Jackbolt Tensioners and Bolting Products

Superbolt provides multi-jackbolt tensioners to replace or retrofit existing nuts and bolts. With their unique and patented design, the Superbolt® multi-jackbolt tensioners can eliminate common problems encountered in today’s critical bolting applications.

Nut or bolt style multi-jackbolt tensioners

A standard nut or bolt style multi-jackbolt tensioner consists of three components:

• A hardened washer that protects the equipment and provides a hardened, flat surface for the jackbolts to "push" against
• A round nut body, which spins on the existing bolt or stud, and seats hand-tight against the washer
• Jackbolts, which thread through the nut body and are used to tighten the joint in pure tension; only hand / air tools are required to tighten any sized Torquenut™ or Torquebolt™

Fast, safe and accurate multi-jackbolt tensioners

Superbolt multi-jackbolt tensioners are very useful for tightening nuts greater than 1in in diameter. As the size of nuts and bolts increase, the load needed to properly tighten them rises. Superbolt products only require hand tools, which results in time consuming, expensive and unsafe bolting equipment such as sledgehammers, hydraulic wrenches and stud heaters being eliminated.

Superbolt’s customers experience dramatic time-savings compared to other bolting methods. Since only hand tools are used, worker safety is greatly increased, and common injuries associated with bolting methods are eliminated.

Superbolt products are accurate, reusable and, because they are tightened in pure tension, can eliminate thread galling and stud seizure.

Customized multi-jackbolt tensioners

In addition to standard products, Superbolt’s engineers have designed many unique products for specific bolting situations.

If companies are experiencing bolting problems such as leakages, thread galling or unsafe working conditions, or are using expensive methods and find it difficult to properly bolt joints, Superbolt’s products could be the solution.

Superbolt provides tensioners in a variety of sizes and configurations. Many items are in stock and are available for immediate shipment.
