【New Product】Can be used without zaguri processing, demonstrating stable waterproofing even with positional shifts! Excellent slip during transportation, suitable for automation! 【Exhibition Participation!】

The "Asufa(R) WP" is a waterproof screw that achieves high axial force, waterproofing, and workability by incorporating an O-ring and flat washer beneath the neck. It can be used without countersinking, and has a wide tolerance range for the screwing position, contributing to improved efficiency and stability in fastening operations. Additionally, the structure makes it difficult for the O-ring to touch the ground surface before fastening, allowing for smooth transportation on a shoot rail. 【Features】 ■ Waterproof performance confirmed for 30 minutes in a submersion test at a water depth of 30 cm ■ Large contact surface that is less likely to sink even when tightened with high axial force ■ No need for countersinking on the fastened item, reducing total costs ■ Resolves supply issues in the assembly process and contributes to automation We will be exhibiting at the "2024 NAGOYA Automotive Technology Exhibition" held at Aichi Sky Expo (Aichi Prefectural International Exhibition Center) from July 17 to 19. Please come and see the actual product at the exhibition venue. *For more details, please refer to the catalog available for PDF download. Feel free to contact us with any inquiries.
