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.
Place two or three drops on the bolt head or the wrench or the socket. Spread it around on the inside of the socket or wrench or the leading edge of the fastener. Wiggle the tool while at the same time applying pressure until you feel a good bite. Cocking the tool slightly to get the proper grip is OK. Maintain the pressure and twist it in or out.
Pipes & Miscellaneous
A drop or two on the teeth of vice grips, pipe wrenches, pliers, etc. will multiply the gripping force of that tool.
