DAP® TankBond® - No More Loose Screws! - Tank Bond™ Thread Stopper™ holds screws and bolts tightly in place. The fast-dry coating creates a tight seal that absorbs shock and vibrations preventing fasteners from unintentionally backing out of wood, metal, and plastic. Simply apply Thread Stopper to screw threads, let it dry, and install the screw into place. Treated fasteners remain completely adjustable, removable or reusable.
