What is productivity improvement
＜Reduction of washer assembly processes＞
These are screws with a built-in washer, such as SEMS screws, or screws with a flange that provides a stable seating surface.
These screws simplify assembly work as they do not require separate washers.
There is no concern about forgetting to attach washers or them falling off.
＜Easy screw insertions in locations with poor workability＞
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.
