Thanks, I was thinking the same thing or a direct tension indicating washer.

You want to think about the effects of combined loading, both bending, shear and normal stress at the weakest part of the bolt. On another note, below the hook lifting devices are covered under ASME B30 and there is another ASME document called ASME BTH-1-2005 which is titled "Design of Below...

Thanks for the reply and for the information on reusable bolts and torque. The ASME standard which does not technically cover this part, but covers similar parts, calls out for a torque rating. I want to start with a recommended torque and then ultimately look at a DTI (Direct Tension...

rmw, Thanks for the reply and for the information on galling. I read up on galling and it looks like the rpm of the installation tool may actually increase the likelihood of galling. I read that if you back down on the installation rpm, it can reduce the galling problems. They also...

Thanks for the explanations. The stainless application that I am looking into is a nut that I had some lab tests done on to determine the yield point for a connection. When I multiply the shear area for the internal thread by the theoretical shear yield stress (30,000 to 32,000 psi x .577), I...

Does anyone know the relationship between shear strength and yield strength of 304 stainless steel or any type of stainless steel for that matter. My Machinists handbook does not list that value for stainless steel. I found on some other old forums on the internet that .577 x yield or .6 x...

This lifting device is neither type, but is a unique lifting device that gets attached to the side of a piece of equipment. Even though it is a unique application device, I was also thinking that a swivel hoist ring would be a better idea for this situation. Thanks for the confirmation.

Thanks everyone. Btrueblood, that was what my gut was telling me about the 0.2% point on the yield curve. I explained to the lab before the test that I wanted the torque, tension and strain measurement on the connection. They have not provided me a stress strain curve, which I think is in...

The bolt is used with a lifting device that does fall under the ASME B30.26 standard, but the standard does not call for a specific torque requirement or test for the bolt. I am doing this not out of a specification or requirement, but I want to give the customer a torque value to work with in...

We recently had some bolts torque tested. The numbers came back 60% higher than the book value for a grade 5 bolt. The method that the lab used was as follows: They increased torque and measured the tension in the connection as the torque was applied. They stopped applying torque once they...
