Haven’t you seen of thick bodied screwdrivers? Hmm I spotted some days back as we had an auto-mobile work happening at our home. It is kind of thick screwdriver which rotates screw easily to the socket and inserted with a downward pressure! So you got a little idea what impact is created on these screw driver bits!! Will share with you what I understood on observing and getting details from the mechanic!
Even some of the screws which are hard to remove or corroded inside are removed using this impact screwdriver. By switching to opposite direction highly torqued screws can be pulled up from the sockets. So the actual process is like the hard core outer sleeve covers the inner region which is typically splined to it. So as you hit the top head with a hammer this spline acts on the inner shield and the high torque results in rotation of the tool in just the opposite direction hence loosening the screw. The same process can be used in the counterclockwise direction to tighten the screws. These screwdriver reduces the tendency to cam out means as the torque is applied by the hammer on the head this won’t easily get slipped off from the screw head. Best for Philips Screws.
You can see the nose of this driver got 1/2 square socket which fits variable sizes of impact sockets! Got a hex adapter for fixing onto Philips and slotted screw heads! This driver is being used to work on hard to reach or hard to operate screws at any region making it an easy tool for many fasteners! You know even I tried out removing one of the pin head hard frozen screw!!
Don’t worry of your delicate hands getting hurt as this got a well cushion comfort grip for ease holding while fast working. Also this kit normally comes with Philips screws, slotted head screws and an adapter which easily fits to the 1/2 square socket.
I say the person who made this tool is really great and got detailed thinking!
