The insert features a 1\/2-13 internal thread and a 3\/4-10 external thread, both UNC standard, with an overall length of 21\/32 inches (0.656 inches decimal). Manufactured from grade 303 stainless steel with a bright finish, it delivers corrosion resistance and a tensile strength of 22,653 pounds. Licensed tradespeople use this insert when repairing stripped threads or installing a smaller internal thread into a larger tapped hole.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in metal fabrication, mechanical maintenance, and industrial repair applications where a reliable UNC internal thread is required in steel, aluminum, or other machinable base materials. It is installed using a standard tap drill and driver, making it a straightforward replacement or thread-repair solution in both shop and field environments. The self-lock wall design resists rotation and pullout under load, making it appropriate for bolted joints subject to vibration or repeated assembly cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 internal thread (Class 2B fit) accepts standard 1\/2-13 fasteners\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 external thread (Class 2A fit) installs into a standard 3\/4-10 tapped hole\u003c\/li\u003e\n  \u003cli\u003eSelf-lock wall design resists rotation and pullout in service\u003c\/li\u003e\n  \u003cli\u003eGrade 303 stainless steel construction with bright finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eTensile strength rated at 22,653 pounds for high-load bolted connections\u003c\/li\u003e\n  \u003cli\u003eOverall length of 21\/32 inches suits standard tap depths in typical parent materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation thread locking insert for applications requiring a 1\/2-13 UNC internal thread installed into a 3\/4-10 UNC tapped hole in machinable parent material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance mechanics using a standard tap and the appropriate insert driver.
