Sunlock is a tapping screw that forms a strong "female thread" with a "small screw-on torque.
The threaded cross section is a non-circular knot shape and the unique shape of turning the apex into a spiral shape allows for small screw torque and smooth threading.
In addition, since the female thread is molded into a plastic processing, there is no cutting and the spring back effect after the molding eliminates the gaps on the screw and female threads, making it a loosening effect. The plastic processing during the molding creates a strong female thread for high holding power.
In addition, it is made of stainless steel (SUS410) with superior "Super Passive Processing (SP Treatment)" (Goal: 500 hours of head release) than conventional pacibate processing, so it has extremely high corrosion resistance.
Features:
The screw part is a "spiral" diaphragm shape.
Female screws are molded with plastic processing.
The screw shape of the sunlock is "round wire".
"SP treatment" with excellent corrosion resistance.
[For this situation]
For continuous screwing
When you want to remove the tapping process.
When you are troubled when the powder comes out.
When exposed to high torque such as thick steel plates
When there is a gap between the bottom holes of the 2-ply planks.
When the female screw is clogged with the paint
