Why should you use a torque wrench to final tighten fasteners and not an impact wrench?
Don’t use an impact wrench to tighten critical fasteners, such as lug nuts, head bolts, main bearing caps and so on. They must be tightened to a specific torque value for different reasons. Stretching the bolt to the yield point evens out the clamping load around the cylinders so the head gasket will seal properly.Click…

Similarly, it is asked, should you use an impact wrench to tighten lug nuts?Do not use the impact to tighten the lug nuts, though. It is very easy to over torque them. Use a ratchet and finish up with a torque wrench for accuracy.Also, can you set the torque on an impact wrench? Currently, none of the cordless impact wrenches will allow you to adjust the torque to those exact settings. (An air impact wrench won’t either for that matter.) The only solution is an attachment that fits onto to the end of the impact and then the socket fits onto it. Simply so, what happens if you dont use a torque wrench? If you tend towards stainless/steel bolts and less expensive components, you can forgo the torque wrench and just ensure you are working to even torque. Too tight on a square taper crankset (specifically the fixing bolt) can cause deformation of the taper fit and eventual loosening of the crank.Why should you use a torque wrench?A torque wrench is used where the tightness of screws and bolts is crucial. It allows the operator to set the torque applied to the fastener so it can be matched to the specifications for a particular application. The most common and prevalent use of a torque wrench is for changing rims.
