BlakeA finished bolt has threading all the way to the head, while an unfinished bolt has a smooth portion near the head with uncut threads. Finished bolts are used in applications where the threading needs to go all the way to the head, while unfinished bolts allow for flexibility in adjusting the length of the thread engagement.

What is the only difference between a bolt of lightning and the spark that is seen between a person's hair and a hard rubber comb used in the hair on a dry day?
The main difference is the scale and intensity of the electrical discharge. A bolt of lightning is a large-scale and high-intensity natural phenomenon that occurs in the atmosphere, while the spark between hair and a comb is a small-scale and low-intensity static discharge caused by friction between materials in close contact.
Is a bolt a type of screw?
Yes, a bolt is a type of screw with a threaded shaft and a head that is designed to use with a nut for fastening purposes. The main difference between a bolt and a screw is that a bolt typically requires a nut to secure two objects together, while a screw can typically be inserted directly into a material.
Is a bolt a second class lever?
No, a bolt is not a second class lever. A second class lever has the resistance between the effort and the fulcrum, while a bolt does not operate in this way.
What is the difference between sheet and fork lightening?
Sheet lightning is a diffuse, illuminating flash that appears as a broad sheet in the sky, while fork lightning is a distinct bolt that resembles a branching fork. Sheet lightning is usually seen as a distant flash with no accompanying thunder, while fork lightning is a more direct and visible bolt that strikes from the sky to the ground.
What causes the electric current that result in lightning?
Lightning is caused by a buildup of electrical charge in clouds. When the charge difference between the clouds and the ground becomes large enough, a lightning bolt is discharged to balance the charge. This sudden flow of electricity forms the lightning seen in the sky.
