They may stretch a little, but thats not totally a bad thing. They probably have entered the elastic stage where they will return to the original length when relieved, but pushed too far they enter plastic stage where they will not return to the original length and begin to neck down, elongate an amount, then break. I inspected the last set I took out, that was tightened the same way and they showed no signs of necking or elongation. Yes I may have overtightened them since you are supposed to reduce the torque 15-20% when using lubrication, but they have been working fine for quite sometime. I would not reuse them again since they are being being pushed to the limit.
