Large Diameter Hydraloc are used where high strength performance is required. They can be placed in all types of load bearing, structural applications and offer tamper-proof joints.
Large Diameter Hydraloc are placed with the help of speciality designed tools, which eliminate installation errors and inconsistent placing of fastener which are usually association with conventional fastening methods. Once placed a visual inception is sufficient to check that fasteners have been installed correctly.
Large Diameter lockbolt joints are permanent and provide clamp loads of over 200 K.N. Large diameter hydraloc joints resist loosening caused by vibration when all other methods of fastening fail.
These fasteners are widely used in heavy duty engineering industries such as
