What happens when a bolt comes loose on a gas line?
If the bolt comes loose, this clamp force weakens. Loose bolts are not just an irritating nuisance. If the joint is not quickly retightened, the application may begin to leak fluid or gas, the bolt may break, equipment may become damaged, or catastrophic accidents may occur.
What happens when you tighten a nut on a bolt?
In a bolted joint, tightening the nut actually stretches the bolt a small amount, like pulling on a stiff spring. This stretching, or tension, results in an opposing clamp force that holds the two sections of the joint together.
What causes a bolt to loosen under vibration?
Washers. Washers are typically wider than the bolt head, with the additional surface area adding extra friction to the joint to maintain the clamp force. However, simple split washers, sometimes called helical spring washers, have been found to actually loosen the bolt under vibration even faster than a joint with no washer.
What causes loose bolts on an ocean freighter?

With this method you will be putting 2-3 cuts in the bolt head or nut. You want to cut just enough that you are almost all the way through the head of the bolt or the nut. You then can hit the cuts with a chisel and a hammer a few times, thus splitting the nut or bolt and relieving the tension on them.
What kind of bolts are used for tapped holes?
Bolts with hexagonal heads and machine threads for use with a nut or in a tapped hole. Also known as hex cap screws or machine bolts.
What do you call a bolt that is threaded on both ends?
A bolt in the shape of a U, threaded on both ends. A countersunk head that has been cut off at 70% of the normal height. Screws in this style will have a second flat surface parallel to the top just before the threads.

How do you remove an extractor from a bolt?
Some work, but many do not. They use hardened bits that grab into the inside of the bolt or nut to remove it. Many require you to drill a small hole in the bolt, then thread these bits in. Whatever you do, do not break the extractor off inside the hole, or you are in for a long, horrible process.

What can I do to keep bolts from falling off?
While these devices do prevent the nut from falling off the bolt, they generally do not help the joint maintain the specified clamp force. Prevailing torque nuts. Nylon or metal inserts inside a nut (sometimes called a “lock nut”) can add extra friction to prevent loosening.
Why are some of the bolts on my car breaking?
By definition, an under-tightened bolt is already loose and the joint does not have enough clamp force to hold the individual sections together. This can lead to sideways slippage between sections, placing unwanted shear stress on the bolt that could eventually cause it to break. Vibration.

What causes a bolt to lose its clamp force?
