Values correspond with actual standards 1) weldable
All given values are leads for minimum tensile strength and minimum torque of a weld without permanent deformation
of parts to be joined. Parts to be joined must have sufficient wall thickness. Values apply for cold rolled threaded studs
with standard thread without surface protection and without thread lubrication. Throughout the entire stud length, at
least the stressed cross section must be present. Values apply for indicated yield strengths.
Material combinations
according to the actual standards (select stud material in a way that material of the
same kind is welded).
