HexForce™ Hydraulic Nut

HexForce™ hydraulic nuts redefine the landscape of large bolt tensioning, presenting a solution that is safe, efficient, and precise. Featuring an internal jack accompanied by an external locking collar, this nut operates by creating a gap between the nut and collar through a combination of joint compression, gasket presence (if applicable), and bolt elongation.

The process begins by pressurizing the nut above the desired preload, followed by the tightening of the collar. Upon releasing pressure, the load is transferred to the collar, albeit with some pre-load loss due to collar thread settling. Notably, this loss is more pronounced with shorter bolts.
