Yes, a screw can be considered a first-class lever. The effort (force applied to turn the screw) acts on the handle, the fulcrum is at the screw's axis, and the load (resistance being overcome) is the material being drilled through.
A screw driver is a class 3 lever, where the effort is between the fulcrum (the place where the screwdriver pivots) and the load (the resistance of the screw being turned).

Yes, a screwdriver is a 2nd class lever. In a second-class lever, the load is located between the fulcrum (pivot point) and the effort force. When using a screwdriver, the fulcrum is the point where the screwdriver rests against the object being turned, the load is the resistance of the screw being turned, and the effort comes from the force applied to the handle.

the pliers are first-class lever is because the pliers have the ankle and the parts to open or screw of something . the object is the front part and the the fulcrum is at the Angel, and the effort/force is in the middle

3rd class lever
A crane is a first class lever when it is winching in or out the rope attached to a load. The crane becomes 3rd class lever when it's boom is luffing, i.e. it is being lowererd or raised.
