Features

A new waterproof screw concept incorporating an O-ring and flat washer. In addition to stable waterproof performance even when misaligned, it also allows for fastening with a higher axial force. It is also ideal for vibration transport.
By using a flat washer to prevent the mating material from collapsing, it is possible to fasten with a “higher axial force.”
Waterproof performance is ensured even when the fastened object is misaligned.
Achieves smooth vibration transport when supplying screws.
