Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm Status: The faster, easier way to work with standards. Worldwide Standards We can source any standard from anywhere in the world. The properties are defined for M1.

The test applies to bolts and screws with thread less than M3 for which no breaking and proof loads are indicated In IS0as well as to short bolts and screws with nominal diameters 3 mm to 10 mm which cannot be subjected to a tensile test. Bolts, screws and studs Part 2: The test result shall not be influenced by head friction or by thread friction. Your basket is empty.
