Screw-Locking Insert: Stainless Steel, 1/4-20 UNC, 2-1/2D MPN:A3585-4CN625

Screw-Locking Insert: Stainless Steel, 1/4-20 UNC, 2-1/2D is a precision screw thread insert designed for use in plastic or weak material bases to provide strong and permanent thread repair without the need for welding or soldering. Manufactured from high-strength stainless steel with a thread diameter of 1/4-20 UNC, this insert is ideal for use in applications requiring resistance to corrosion and high torque loads such as fastener replacement, tapped holes or assembly connections in metal and plastic components. The unique locking design of the screw-locking insert ensures secure and reliable retention in place while maintaining a smooth surface finish on both mating materials for reduced friction, wear, or stress concentration points. This helical insert is essential for aerospace, automotive, medical or manufacturing industries where high-quality thread repair and reliability are critical to ensure performance and safety of components under demanding conditions.
