TORQUE CALCULATIONS

02/01/2009 1:56 PM

WHEN WE ARE USING AN M10 STANDARD(METRIC THREAD)BOLT LENGTH 65MM . FOR THIS BOLT HOW WE CALCULATE THE TORQUE VALUE FOR TIGHTING THE BOLT IN THE 70MM FEMALE THREAD(METRIC THREAD) IS THERE ANY CALCULATION FOR TORQUE SETTING .

ANOTHER DOUBT IN THE TREADS WE ARE USING BSP,NPT, MM WHAT IS THE DIFFERENTS IN THEIR PITCH HOW TO FOUND THESE THREADS IS THERE ANY RULES IS THERE HOW TO CALCULATE PLS GIVE SOME TECHNICAL INFORMATION ABOUT THREAD CALCULATIONS

You have some other posts that are "yelling" as well, please take the advice on the first response and don't put everything in caps.

Try a book like Machinery's Handbook or find a spec sheet to find torque required.

You just need to buy a manual or handbook what brings the differents standards of threadings, and all that simple workshop basis like the "Oberg-Jones" or the "Colvin-Stanley".-

From CMTI Machine tool design handbook we can find tighting torque

For M10 grade 6.6 Fasteners tighting torque is 1.4 kgf.m

It is always difficult to calculate torques required for particular industry as all have slightly different requirements and needs.

I find it best to make an excel sheet using data from the net or books and then modify the values to suit. Try a link like http://www.efunda.com/designstandards/screws/calc_bolt_torque.cfm

Torque requirements are affected by material, lubrication, surface finish and so on. I have never found one value for any screw or bolt to suit all. You need to modify the values to the particular industry or even company you are involved in.

The different threads are for different purposes and have requirements to suit.

Try the Machinery's Handbook under screw thread systems. It has BSP, Whitworth and the rest. If necessary the supplier can get you the information required.

I am sure there is also information under specific threads on the net - the hand book is a good start.

Hope that helps
