Product Training

Too often joint integrity is compromised by the use of sub-standard and poor quality fasteners, risking catastrophic failure and the consequences that follow.

In 95% of all joint failures attributed to fastener fracture, the root cause has been incorrect specification or misuse. Lack of education is a significant contributor to the problem. Ajax Engineered Fasteners has been conducting product training in Australia for many years, and now presents updated versions of all the material.

This training program will provide engineers, architects and purchasers to correctly specify fasteners, which will help to eliminate the the use of sub-standard fasteners from critical applications.
In the coming weeks, new material will be made available for downloading from this site.
