The Hex Wrench Key is designed specifically for Bell shields and is used to change the shield's pivot screws, tighten the friction screws, and adjust the shield lock down button.

 

The Hex Wrench Key is also used to uninstall and install replacement shields. Using this key greatly reduces the likelihood of over-torquing pivot kit bolts and screws and damaging shield inserts. The straight-edged side of the key is designed to turn and tighten tearoff posts when installing tearoffs.

 

Every Bell racer should have at least one of these keys in their toolbox.
