When a bolt or screw is threaded into the Well Nut, it compresses the rubber or elastomer, causing it to expand and create a tight seal against the inside of the hole.Attributes:• Designed to withstand high temperatures.• Help absorb shock and reduce noise.Applications:A Well Nut is used to provide a secure and reliable connection between two surfaces.
