Manufactured from Grade 304 stainless steel with a bright finish, this insert provides corrosion resistance in demanding service environments. The 8-32 UNC thread size and 1D length ratio (0.164 inches overall length) make it a compact solution for restoring or reinforcing threaded connections in metal components. A maximum locking torque of 9 in-lb and a minimum breakaway torque of 1.50 in-lb keep fasteners secure under vibration and dynamic loading. Licensed machinists, maintenance technicians, and assembly professionals install these inserts in production and repair applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for use in aerospace, electronics, industrial equipment, and general manufacturing applications where reliable thread locking is required. The tangless design eliminates the need for tang removal after installation, streamlining the assembly process and reducing the risk of loose tang fragments in sensitive components. It is commonly installed in aluminum, magnesium, cast iron, and other base materials where parent thread strength is insufficient for the load requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 304 stainless steel construction for corrosion resistance in harsh environments\u003c\/li\u003e\n\u003cli\u003eTangless design eliminates post-installation tang removal step\u003c\/li\u003e\n\u003cli\u003e8-32 UNC thread size with 1D length-to-diameter ratio\u003c\/li\u003e\n\u003cli\u003eMaximum locking torque of 9 in-lb for vibration-resistant fastening\u003c\/li\u003e\n\u003cli\u003eMinimum breakaway torque of 1.50 in-lb ensures controlled removal when needed\u003c\/li\u003e\n\u003cli\u003eBright finish with minimum OD of 0.205 inches and maximum OD of 0.220 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style thread repair and reinforcement insert for tapped holes requiring 8-32 UNC threading in metal base materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a HELI-COIL or compatible tangless insert installation tool matched to the 8-32 UNC thread size. The parent material must be tapped with the correct STI (Screw Thread Insert) tap before insert installation. Power down or de-energize any equipment before performing thread repair on live assemblies.
