Shake the bottle well. Apply a single drop either into the slot or onto the tip of the screwdriver. Insert the screwdriver into the screw slot. Apply pressure and wiggle the screwdriver until you feel a good grip. Keep the pressure on and then twist it in or out. When using a power driver, it's very important that you wiggle the screw bit with pressure, once again to be sure that you get a good bite prior to giving a burst of power. EZ-Grip is also excellent to use as a preventative. Use a drop when inserting a new screw to help prevent slippage and damage to the fastener. It also reduces the wear on the screwdriver bit.
