  • Integrated locking and sealing fastener with electrical conductivity
    Patent number: 10594050
    Abstract: An integrated locking and sealing fastener with electrical conductivity is revealed. The integrated locking and sealing fastener with electrical conductivity includes a fastener with a surface and a conductive anti-loosening coating. A part of the surface of the fastener is a fastening contact surface and the conductive anti-loosening coating is formed on the fastening contact surface. The conductive anti-loosening coating consists of an anti-loosening portion and a conductive portion mixed with each other. The anti-loosening portion is made from polyamide (PA) resin, acrylic (PMMA) resin, polyethylene, epoxy resin, silicone, rubber, or the combinations. The conductive portion is made from materials including carbon black, metal powders, a silver wire, graphite, or the combinations. The coating on the fastener not only prevents loosening and leakage but also provides electrical conductivity.
