What happens if I Overtorque a bolt?
Everyone who has ever worked with fasteners has accidentally messed one up at some point. One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.
What happens if you overtighten a bolt?
Yes, you can over-tighten a bolt, but doing so is unlikely. Most bolts come with instructions that the bolt’s maximum torque. The ó-inch Power Bolt, for example, has a maximum torque of 25-foot pounds.
How do you check if a bolt is over torqued?
The movement check: After fastening the bolt, make use of a torque measuring tool to mark off the tightened bolt and the product/workpiece. Apply additional force in the tightening direction until movement is noticed. Recording the reading will indicate the residual torque originally applied to the joint.
How tight should bolts be?
In general, you should make the bolt tight enough so that the items it is holding together stay together, but not so tight that you damage the bolt’s threads. You should tighten bolts properly so that the bolt performs properly.
Should you tighten the nut or the bolt?
There is no simple answer to this as in some instances, it is perfectly acceptable to tighten the bolt head while holding the nut in place. In other situations, it’s acceptable to tighten the nut.
Can you over tighten U bolts?
Impact wrenches can over or under torque the U-bolt, thus resulting in a failure to the U-bolt by over torquing or the spring by under torquing. Tighten all U-Bolts until they are snug only.
Is it OK to reuse U-bolts on leaf springs?
While the U-bolt has some flexibility in its ability to stretch after being loosened, the bolt will never tighten enough to allow it to regain its full torque spec potential. The next issue with trying to reuse U-bolts has to do with the threads themselves. When being tightened, the threads stretch out under torque.
Do you have to replace U-bolts when replacing leaf springs?
U-bolts are a vital part of your suspension system and should never be reused. Failure to replace or properly fit your U-bolts when maintaining or servicing your suspension could cause premature failure of your leaf springs or other components with catastrophic results.
Should leaf springs be lubricated?
The springs should be kept fairly clean in order to extend their useful life. Modern leaf springs do not need lubricating with oil — which may damage any anti-friction material between leaves. Spray them instead with a silicone-based lubricant.
What should I put between leaf springs?
Lift Blocks. Lift blocks can be used between your axle and leaf springs in a spring-over configuration. They increase the distance between the axle and the spring pack.
How often should leaf springs be replaced?
On average a set of leaf springs for a standard pickup truck or van will have a lifespan of about 200,000 miles. This number is not written in stone, and some vehicles will break their springs with far less than 200,000 miles on them while others will go well beyond the 200,000 mile mark before they break.
