Lockbolts and Collars (RivBolts)
The Lockbolt fastening system was developed to provide an alternative to the already successful Industry Standard Leader.
After many years of development, investment and independent testing to the highest industry standards, the product has won approval all over the world. It is now sourced globally by both OEM users and Repair Shops.
Our customers benefit from the experienced technical advice and support we offer. A product that is fully compatible with existing systems and above all is very cost effective when compared to the other lockbolts that are available.
The high tensile and shear strength of the installed RIVBOLT, provides a joint with very high resistance to vibratory loosening. This ensures that all fasteners are installed with the same results under all conditions.
Visual inspection of the installed fasteners eliminates the need for expensive equipment and time-consuming inspection methods.
