How reproducible would a torque wrench be?
|
I used torque wrenches in car engines where the torque on some bolts need to be the same .E.g. the bolts on a given engine need to be at 150 PSI. How do you know that the 6 or 12 bolts are at 150 PSI? You use a torque wrench. I have seen two types; one with a dial and the other where you set the torque and the wrench slips when that torque is reached. This would also eliminate the need for things such as “thread count” that can be highly unreliable. The type of spring would also not matter, as long as the spring can provide the PSI desired. E.g. you wont use a spring capable of providing only 10 PSI when 16 PSI is needed. So you could have a 25-PSI half compression spring and I could have a 30-PSI half compression spring it would not matter using a torque wrench because the setting would only allow – lets say 16 PSI.
