Wonder Bar Pressure Bolt

Home / Windshield Crack Master Parts / Wonder Bar Pressure Bolt

The Ultra Bond Wonder Bar Pressure Bolt is used to increase pressure and allow for the windshield repair resin to fill of the drill hole during long crack windshield repair and during windshield chip repairs. Use it on the old long crack tool with our 3/16-8 leveling hex nut placed at the top of the threads, beneath the head. This will turn the long crack tool into a self-leveling tool  and or no leveling or adjusting will be needed once you bring the injector level.
