AS FA WPBest of bothAxial force and Waterproof With the electrification of automobiles, water-cooled thermal controls are on the rise. Even for fastening parts, there is a growing need for both waterproofing and axial force. This product is a new concept waterproof screw that incorporates a flat washer in addition to an O-ring underthe neck. By securing a sufficient contact surface, the screw can be fastened with a higher axial force without denting the clamped part. In addition, the O-ring is positioned around the periphery of the screw head, ensuring consistent water sealing performance even if misalignment of fasteners occurs. Also in the automatic screw fastening process, the flat washer(metal) contacts the chute rail of the screw feeder, prevents screw jamming.

Waterproof Conventional If misalignment of fasteners occur, the O-ring will not be compressed and waterproof performance cannot Since the O-ring is positioned on the periphery of the screw head, it is unaffected by misalignment of fasteners. Therefore, the O-ring provides a consistent waterproof performance. Automation Conventional The flat washer holds the O-ring and prevents it from falling. In addition, by taking place contact surface from rubber to metal, it improves flow of screws on chute rail. Fastener Division Global Sales Section Website : https://global.nittoseiko.com/
