Aspha(R) WP O-ring + flat washer New waterproof screw
The waterproof screw "Asfa(R) WP" combines stable waterproofing with high axial force due to sinkage reduction.
"Asufa(R) WP" is a newly conceived waterproof screw that incorporates a flat washer in addition to an O-ring located beneath the neck. Since the O-ring can be positioned on the outer circumference of the screw head, it maintains stable waterproof performance even if the fastening element shifts. Additionally, it secures sufficient contact surface, allowing for fastening with higher axial force without causing the fastening element to sink. Furthermore, in the automatic screw tightening process, the flat washer (metal) makes contact with the chute rail of the screw supply machine, enabling smooth transportation. [Features of Asufa(R) WP] ■ Provides stable waterproof performance with minimal impact from the shifting of fastening elements. ■ Allows for fastening with higher axial force by reducing the sinking of fastening elements. ■ Achieves smooth transportation by having the flat washer contact the chute rail in the automatic screw tightening process. *For more details, please refer to the PDF document or feel free to contact us.
