Universal stud HZ-1 with centre point steel 8.8 suitable for welding (black burnished)
The new SOYER bolt generation "Black Series" of strength class 8.8 is characterised by a full colour marking in black by burnishing. This eliminates the risk of confusion between bolts of the same shape with lower strength classes. This new high-strength bolt type replaces the previously used and comparatively low-strength weld studs made of unalloyed steel of strength class 4.8.
