Asfa(R) WP for Home Appliances - Balancing Waterproof Performance and Workability
No need for ZAGRI processing! O-ring embedded screws that achieve high axial force and waterproofing.
In the home appliance industry, as products become smaller and more functional, measures to prevent failures due to water exposure have become important. In particular, products intended for outdoor use or those designed for use in wet areas require high waterproof performance. Traditional waterproofing measures often necessitate counterboring, which can lead to increased costs. The Asfa(R) WP is a waterproof screw that achieves high axial force and waterproofing by incorporating an O-ring and flat washer beneath the head. 【Usage Scenarios】 - Outdoor-installed home appliances - Kitchen appliances - Bathroom televisions - Washing machines 【Benefits of Implementation】 - Elimination of the need for counterboring, reducing total costs - Improved product reliability due to high waterproof performance - Contribution to the efficiency and automation of the assembly process
