Why is the nut hanging off the end of the bolt?
The nut may not be hanging off the end of the bolt after tightening is completed. When the outer face of the nut is flush with the end of the bolt, the bolt’s ductility is at its greatest. This is because the maximum amount of threads are exposed, allowing the bolt to stretch as much as possible.
Are there any safety issues with long bolt flanges?
The issue of long bolt flanges arises from an audit finding, where it was stated that long bolt flanges are more susceptible to increase the rate of fueling a fire than conventional flanges. In this regard, I am looking for information to back up the current practise of using long bolt flanges – ie these are no more dangerous than normal flanges.
What causes a bolt to remain loose after installation?
Depending on your installation method, the following could occur: Calibrated Wrench or Twist-Off Methods: The bolt will not be properly pretensioned, due to the nut ceasing rotation, while the torque remains high. This causes the bolt to remain loose.
What happens if you tighten a bolt and it spins?
So you don’t have an issue “currently” with a spinning bolt. However, your bolt isn’t spinning because you have managed to over tighten it. This too can be harmful to whatever project you are doing. When you over tighten or over-torque a bolt you could strip the bolt or even snap the screw heads.
The nut may not be hanging off the end of the bolt after tightening is completed. When the outer face of the nut is flush with the end of the bolt, the bolt’s ductility is at its greatest. This is because the maximum amount of threads are exposed, allowing the bolt to stretch as much as possible.
What happens if you tighten two bolts at once?
If tightening is continued, the force between the two nuts will continue to increase. If the thick nut is overtightened, there is the risk of thread stripping or the tensile fracture of the bolt between the two nuts.
Where do you put the thin nut on a bolt?
Sometimes the thin nut can be observed below the standard thickness nut and on other installations, it’s on top. Although it may seem counter-intuitive, the thin nut should go next to the joint and not be put on last. In other applications, for example on column attachments, two standard thickness nuts are frequently used.
Depending on your installation method, the following could occur: Calibrated Wrench or Twist-Off Methods: The bolt will not be properly pretensioned, due to the nut ceasing rotation, while the torque remains high. This causes the bolt to remain loose.
Why does a structural bolt have a maximum stickout?
When the outer face of the nut is flush with the end of the bolt, the bolt’s ductility is at its greatest. This is because the maximum amount of threads are exposed, allowing the bolt to stretch as much as possible. Structural Bolt Stickout Maximum
What happens when a bolt breaks off a car?
Once a bolt has broken or sheared off its head, an inevitable sense of panic always strikes the one who broke the bolt. Because the subframe bolts on most vehicles are so low to the ground, this is a fairly common occurrence.
