ITH Engineering Product: IHF Fasteners
Description: IHF fasteners are designed for use with ITH tensioners to achieve maintenance-free bolted joints. The optimized design eliminates the need for washers and allows high utilization of the yield point, small bolt dimensions can be used with the same tensioning force.
Application: IHF fasteners are generally used in steel construction, especially on flanges. Available standard dimensions are: M36 to M64 (1 3/8" to 2 1/2")
Key Features:
• DIBt approved;
• Maintenance-free;
• Substitute common bolts and nuts;
• Highest accuracy and repeatability in clamp loads;
• Flanges can be designed more compact and reduce costs.
