Series CH, CHS & CHA self-clinching flush head studs are designed for permanent installation in thin sheet materials while maintaining a flush external surface. Engineered for high torque-out and pushout performance, these studs provide strong, vibration-resistant fastening without welding or secondary operations. The flush-head profile is ideal for applications requiring smooth panel surfaces, including enclosures, sliding assemblies, and precision equipment. Available in heat-treated carbon steel, 300 series stainless steel, and 2024-T4 aluminum, the range supports varying strength, hardness, weight, and corrosion-resistance requirements across industrial and electronic assemblies.
