Manufactured from Grade 304 stainless steel with a primer-free finish, this insert accepts a 2-56 UNC thread and features a 1D length-to-diameter ratio with an overall length of 0.086 inches. Three free coils provide the locking action, delivering a maximum locking torque of 20 oz-in and a minimum break-away torque of 3.00 oz-in. The tangless design eliminates the need for tang removal after installation, saving time and reducing debris in critical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications requiring reliable thread repair or thread reinforcement in soft or brittle base materials such as aluminum, magnesium, and plastics. The 2-56 UNC sizing targets small-fastener assemblies common in precision instrumentation, electronics enclosures, and light mechanical assemblies. Installation is performed by technicians and assemblers working in aerospace, electronics manufacturing, and general industrial maintenance environments where thread integrity and torque retention are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design eliminates post-installation tang removal and reduces assembly debris\u003c\/li\u003e\n  \u003cli\u003eGrade 304 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 20 oz-in with minimum break-away torque of 3.00 oz-in\u003c\/li\u003e\n  \u003cli\u003ePrimer-free finish for clean installation without additional prep\u003c\/li\u003e\n  \u003cli\u003e1D length-to-diameter ratio with 0.086-inch overall length suits tight-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003eThree free coils deliver consistent thread-locking performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw-locking insert for 2-56 UNC tapped holes in base materials requiring thread reinforcement or repair.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using the appropriate tangless installation tool sized for 2-56 UNC inserts.
