For M3 the body diameter is 2.5mm, the section area is 6.25mm2 Let the ultimate strength be 250/mm2 6.25 * 250 = 1562N The thread develops a stress concentration, and a significant safety factor must be considered. So actually M3 holds less 500N. ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
