HNTC Top Collar Hydraulic Nuts

HNTC hydraulic nuts are used as a direct replacement for existing conventional nuts. They allow precise loading of the bolt, after which this load is permanently held by means of a locking collar.

PAL – Pure Axial Loading
TensionPro hydraulic nuts ensure that bolts are loaded with a precise force that is directly proportional to the pressure applied to the tool.

Friction-Free
Friction-free bolt tensioning ensures an accurate and repeatable tightening method.
The tensioner force or load is easy to calculate using the formula:
F = (P × A) / 10,000, where F is the tensioner force in kilonewtons (kN), A is the tool pressure area in square millimeters (mm²), and P is the applied pressure in kilonewtons (kN).
