Hentec provides stud bolts and standard fasteners according to agreement.
Achieve higher remaining pre-stress in your tensioned bolt connection by using ITH round nuts.
The IHF system is designed to replace commonly used HV-fasteners by integrating the washers to the bolts and nuts. Available in sizes M36 to M64 and produced by cold forging.
If a tightening method change is needed from torquing to tensioning, a common problem is that the existing bolts are too short and have insufficient thread projection for tensioning cylinders. The tension nut replaces the hexagon nut and extends the thread, enabling the application to utilize the existing bolts.
