Screw torque for grub screws

[mbrett]

Does anyone know where I can get information on screw torques for standard metric grub screws. As they do not have a conventional screw head I have a feeling that standard screw torque equations will not work. At present I am looking at cup point grub screws.
Als is there any information out there on the different types of grub screw?

Try these two sites and ask the company for torque specs.

http://www.microplastics.com/detail.asp?part=metgrubscrew&fam=screws

and

http://www.rctek.com/fixings/info_fixings_grub_screws.html

The first site has a mechanical properties section but I didn't see grub screws but the company should have data. The second site shows types of grub screws.
Hope this helps some

I forgot to ask, what material are they to be made from? I have other sites for different materials. Sorry!

The grub screws I'm working with at the moment are stainless steel grub screws in a brass insert. Martyn Brett
