Designed to replace standard coupling bolts, the Riverhawk Hydraulically Fitted Coupling Bolt (HFCB) reduces installation and operational problems created by the use of old style coupling bolts. During installation of traditional bolts the required tight tolerance fit insertion into the bolt hole will sometimes cause damage to both the bolt and hole. This can cause galling of both parts thus hampering removal and extended down times.

In addition, as a traditional bolt is stretched its diameter is decreased creating increased clearance between the bolt and the hole. When this occurs concentricity can be lost and the chances of slippage are increased creating excessive vibration, which leads to forced outages and lost revenue.
