There is no dilference in the above chart between the torque figures for fine or coarse threads. The torque tigur€s for a f¡nely.threaded fastener as conpared to a coarsely-threaded lastener of the same d¡ameter may be sl¡ghtly higher but h;rdly worth mentioning. CAUTION
There are many varying tactots which affect torque. The figures ¡n this chart are sale figures for standard torque applications only.
