Self-drilling screws of stainless steel for soft metals (e.g. aluminum, etc.) The low torsional strength and surface hardness of the self-drilling screws of stainless steel sets the limits to connect component strength and present surface condition. Setting for rotational speed, tightening torque or to establish a possible core hole shall be determined experimentally.
Plastic torsional deformation must be avoided by assembling!
