Someone else pre damaged these, I went with this type.First you need a GOOD bit that fits the screw. Second, use an impact if you cant get it loose by hand. MUST keep the bit straight into the screw or it will flair out. Real easy to move to the side while twisting. 1/4 drive impact works great for smaller screws, bolts, nuts, etc. Torx or square drive is the best way to go.
Same principal the had held impact's work on but I can never remember which way to turn the darn thing so don't use it.I found seating the driver in the screw & tapping it lightly not only seats it but gives the screw head a slight impact to break the hug they have on what their holding.
AFAIK the main advantage and IIRC the original goal of the Phillips was to get the driving tool to "cam out" when an appropriate torque is reached as to accelerate assembly lines.Their big advantage is in assembly work and alignment of the driver is not as critical as some others.
