Screw Thread tension Calculator

We require simple Bolt tension/compression calculator which uses bolt diameter, thread pitch, input torque etcetera as variables, preferably in an well known spread--sheet pro--gram.

The basic objective is to be able calculate bolt tension/compression (in N and kN) and minimum thread length required with the following

**** input variables,

* Thread diameter

* Thread pitch (Dropdown for single start ISO Metric, ACME, UN, UNC, UNF etcetera thread forms)

* Input torque, (Nm)

* Material grade, (Dropdown for Bolt material Grades 4.4 to 12.9 and particularly B7)

* Friction Coefficient (Dropdown for Lubricated, Dry, Zinc coated, PTFE coated)

* FOS (in % of Yield)

* and others that will make a significant contribution to the output.

*** Output Data

* Tension/Compression Force (N kN)

* Stress (Mpa)

* Minimum recommended thread engagement length (this is optional)

This is essentially a thread sizing/selection tool for the early design phase of a mechanical assembly.

The well known spread--sheet pro--gram would output numerical values as a minimum with Grap-hical representation being a nice to have

The person best suited for this work will be a qualified Engineer or PHD who has an in-depth knowledge of threaded bolting, fastener and lead screw systems and force/torque calculation of same.

The person will also have a good knowledge of calculation in the well known spread--sheet pro--gram.

For security, verification and auditing the well known spread--sheet pro--gram shall be unlocked, not employ V-B-A or mac-ros.

A possible (but not guaranteed) follow on of this work will be a conventional fastener calculation that will then be subject to third-party verification.

Any questions and or suggestions, please feel free to ask.
