It is kinetic energy.
I bet the expression you're thinking of is "hit the nail on the head" which has to do with striking a hammer against a nail perfectly on target. So the expression means to say something that really thoroughly answered the question. Maybe "hitting the rail on the head" is just a Mondegreen.See related question below for information about Mondegreens.
An 8 penny nail (abbreviated as 8d) is 2.5 inches in length. A 10 penny nail (10d) is 3 inches in length.

There are several places where someone could purchase 3D nail stickers. Retail stores such as Target, Walgreens, Toys R Us, and Walmart all sell 3D Nail Stickers.

An example of impact force is when a hammer strikes a nail. The force of the hammer hitting the nail causes an impact that drives the nail into a surface.
nail forcing the hammer
The force exerted by a hammer hitting a nail is a contact force, specifically a compressive force. This force overcomes the resistance provided by the nail and drives it into the surface.
The action force is the hammer exerting a force on the nail to drive it into the surface. The reaction force is the nail exerting an equal and opposite force back on the hammer according to Newton's Third Law of motion.
The force of the hammer is much greater than the force of the nail. Gravity pulls down the hammer, hits the nail, and the nail forces up, but the force of gravity wins over the force pulling on the nail.
Hitting a nail with a hammer involves pushing the hammer down onto the nail to drive it into the surface. So, it is considered a pushing action.
You should practice hitting the nail very slowly but with force. You cold also try wearing gloves for the extra protection.
When you hit a nail with a hammer, the force is applied at the point of contact between the hammer and the nail. This force drives the nail into the surface it is being hammered into.
The effort force is applied by the person using the hammer to pull the nail out. The person exerts force on the hammer which transfers the force to the nail, causing it to be pulled out of the surface.
When a hammer hits a nail, the force applied by the hammer causes the nail to experience an equal and opposite reaction force. This reaction force drives the nail into the surface it is being hammered into.
The action force is the force exerted by the hammer on the nail. The reaction force is the force exerted by the nail on the hammer, according to Newton's third law of motion.
The reaction force when a hammer hits a nail is called the law of motion. This motion falls under Newton's Third Law.
