Screw-Locking Insert: Stainless Steel, 1/4-20 UNC, 1-1/2D MPN:23043L

This stainless steel screw-locking insert offers enhanced retention for fastening applications subject to shock, vibration and torque through its unique design that eliminates the need for locknuts or additional locking mechanisms. Its drive size of 1/4-20 UNC is complemented by an anti-seize compound coating on the threads which protects against corrosion and galling, making it ideal for use in harsh environments such as marine and offshore settings. The hexagonal socket provides convenient tightening access even in confined spaces while the diametral depth of 1-1/2D times the screw diameter enhances gripping strength for secure retention. With a wide range of industries including automotive, aerospace, military and defense as its user base, this product offers reliable self-locking functionality tailored to demanding applications where traditional fasteners fall short. From structural joints and pivot points to heavy machinery components, the screw-locking insert delivers optimal performance in critical situations where strong retention is needed.
