How do you tighten a stud?
Use a wrench to tighten the lower nut against the upper one, jamming them together (you’ll need a wrench to hold the upper one as well to prevent it from turning). Next, place a wrench on the lower nut and turn it counter-clockwise; the stud should walk right out.
Why do you tighten the nut and not the bolt?
In many situations you can apply torque to either the nut or the bolt head. Both will result in a tight connection and neither will avoid breakage more often (that occurrence can be avoided through other means). In certain circumstances, however, you will need to torque one and not the other.
Does it matter if you torque the nut or bolt?
The question is often asked as to whether the nut or the bolt head should be tightened. The answer depends upon which tightening process is being used. For torque controlled tightening whether the nut is tightened and the bolt head held, or the bolt head tightened and the nut held, can be of importance.
Should studs be torqued?
On re-install the lower of the two nuts on the strut top should be torqued to 58 ft/lb before the strut goes in the car. Once in the car, install the upper top strut nut, but don’t torque it yet. Install the strut to knuckle bolts.
Can you reuse head studs?
Yes. As long as the fasteners have been installed and torqued correctly, and show no visible signs of damage, they can be re-used. If they show any signs of thread galling or corrosion, they should be replaced.
Does washer go with nut or bolt?
If there is only one washer used with a nut/bolt, it usually goes on the nut side. The nut in most circumstances is more movable, and is more commonly turned to tighten the assembly. The washer helps prevent damage to the surface of the object being fastened.
How tight should strut bolts be?
You should leave them just about snug, if not just a little loose. If you tighten them before you put it on the ground, when you do get the car on the ground, there will be tension on the parts, which means it will wear quicker.
How much does it cost to tighten your shocks?
you dont need to torque the old post top shock, ones with two rubber washers and the nut. Just tighten the nut down till the rubber washer is just starting to squish, then go about 5 turns more. kinda in the middle of when it starts to squish and before you totally colapse it .
What should be tightened-the nut or the bolt head?
Some people believe that by tightening the bolt head rather than the nut it will affect the torsion in bolt shank. The torsion in the shank of the bolt depends upon the thread friction torque. For a given finish condition, the thread friction has some scatter associated with it, but will not depend on whether the nut or the bolt head is tightened.
Which is better a bolt or a stud?
Stud vs bolt: strength, clamping force, torque As discussed earlier, the stud obtains much more accurate torque values and that’s mainly because the studs don’t twist during tightening. The studs do not move during nut tightening and because of that the stud stretches in one axis, which provides much more correct clamping forces.
How to tighten engine bolts the right way?
1 Tighten all bolts in sequence, and in two stages to a snug torque value of say, 30 Nm 2 Apply a 90 degree rotation to all bolts in the proper tightening sequence 3 Apply a further 90 degree rotation to all bolts in the proper tightening sequence
Which is the correct way to tighten a cylinder head?
For example, a typical cylinder head tightening sequence might look like this- Tighten all bolts in sequence, and in two stages to a snug torque value of say, 30 Nm Apply a 90 degree rotation to all bolts in the proper tightening sequence Apply a further 90 degree rotation to all bolts in the proper tightening sequence
