How is the thin nut tightened in a jam nut assembly?
In assemblies with jam nut, the thin nut is first tightened against the assembled parts and then the regular or high nut is tightened against the thin nut.” You may also be interested in an article published on this topic:
What happens if you tighten the top nut on a fastener?
Continuing to tighten the top nut results in the jamming of the threads leading to F3 > F2. 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.
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.
What happens when you drive the left hand nut too far?
In general, although there are exceptions such as the left-hand nut, spinning to the right tightens and spinning to the left loosens (“righty-tighty, lefty-loosey”). The problems start when fasteners are driven too far, or over tightened.
Why are the lug nuts on my car overtightened?
More likely, the lug nuts were overtightened. Tom: Here’s the likely scenario: When you had your stabilizer replaced 3,000 miles ago, someone overtightened your lug nuts. What that does is it stretches the studs. Now, every metal has an “elastic region,” a point to which it can be stretched and still return to its original shape and size.
