How to determine installation torque for stainless steel bolts & machine screws?

more accurate method of determining installation torque for stainless steel bolts and machine screws is to perform a torque-to-failure test using the actual application conditions. The recommended steps are, Construct at least 10 assemblies of the application joint.

Can a torque calculation be used for stainless steel threaded fasteners?

As explained, a common torque calculation can be used for carbon steel fasteners. However due to differences in material behavior, this calculation is not suitable for stainless steel threaded fasteners. Two alternative methods were presented that may provide suitable installation torques.

What torque range should be used for tightening long locking screws?

For tightening of the long locking screws (pos. 1, e.g. drawing 190.0309-XX-B01) the torque ranges of Table 7 are recommended. *) The torques ranges are not valid for O-ring discs and sealing plates designs. In case of need they have to be required at TB/DD.

What is a good installation torque for fasteners?

During its assembly, the installation torque for such fasteners is essen-tially zero. Upon curing, the pre-mixed chemicals develop a very strong bond between matting components that has high break-loose torque. The cleanliness and type of basic substrate is important.

How much torque can a carbon steel screw re-use?

A ±10-20% range is common and depends on the accuracy of the operators, equipment, installation rpm and torque magnitude. In general as long as a carbon steel bolt or machine screw has not been torqued beyond the material’s yield strength, it can be considered for re-use on non-critical joints or applications.

What is a bolt torque calculator?

The Bolt Torque Calculator from Engineers Edge estimates the unknown torque, diameter, axial force applied, and coefficient of turning friction for given conditions. It uses the basic elastic torque-tension equation and provides a practical starting point for all threaded fastener tightening analysis.
