"These devices measure clamp load and not torque. They will also tell you relaxation in the connection [and] allow equipment to be inspected in use without shutdown. They reduce [Preventative Maintenance] costs immensely. The price of these are a cost savings compared to any traditional PM schedule in expensive, safety or mission critical equipment. One breakdown will most likely cost you more than the upfront cost difference in the bolts. I have used them in drive systems in excess of 3000 kN*m output torque and rugged specialty vehicles."
