Insert the bolt into both throughholes on the components and, with the chamfer aligned to the end of the bolt, slide the collar over the lockbolt. (Fig. 1)

Fully press the installation tool with attached pulling head against the collar while securing the pin in place from the opposite side to prevent it from being poked out. (Fig. 2)

Press the trigger on the installation tool. The jaws then grip into the grooves on the pin tail and tug at the pin. The pulling head sleeve presses up against the components and the resulting clamp force pushes them together. (Fig. 3)

As the tool continues to pull, the pulling head sleeve slides over the collar. (Fig. 4) This reduces the external diameter of the collar. The compressed material slides into the locking grooves of the bolt to form the desired positive fit. As the front side of the sleeve elongates, it is pushed up against the component to create the desired preload where the parts connect.

The tool will continue to pull until the lockbolt’s preload is achieved, causing the tip of the bolt (pulling head) to snap off at the end of the collar. Installation is now complete. (Fig. 5)
