What is galling & seizing prevention
＜Galling prevention by surface treatments＞
By reducing the friction coefficient of the thread surfaces with plating or coatings, the required axial force can be achieved with lower tightening torque.
As a result, he generation of friction heat during tightening is minimized, effectively preventing galling and seizing.
There are surface-hardened screws that do not cause contamination, as well as screws with gold, fluorine, MoS2, and PTFE coatings.
＜Galling prevention with guided screws＞
Galling prevention with guided screws
Guides at screw tips enable easy vertical insertions into internal threads even in locations with poor workability, preventing galling and breakages caused by angled tightening.
