Constructed from Grade 304 stainless steel with a dry film lubricant finish, this tangless insert measures 0.492 inches in overall length at a 3D length-to-diameter ratio for the 8-32 UNC thread size. The locking feature is built into the coil geometry, eliminating the need for a tang removal step after installation. Licensed machinists, maintenance technicians, and assembly professionals use this insert to restore or reinforce threaded connections in metal components.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for applications where thread locking and corrosion resistance are both required, including aerospace, marine, industrial equipment, and precision machinery. The tangless design is preferred in blind-hole applications and automated assembly environments where tang removal is impractical or risks contamination. Grade 304 stainless steel construction holds up in wet or chemically active service environments. The 8-32 UNC thread size is common in light mechanical assemblies, electronics enclosures, and instrument panels where small-diameter fasteners carry moderate loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTangless design eliminates tang breakoff, reducing debris and simplifying blind-hole installation\u003c\/li\u003e\n  \u003cli\u003eGrade 304 stainless steel construction provides corrosion resistance in wet and chemical environments\u003c\/li\u003e\n  \u003cli\u003eDry film lubricant finish aids installation torque control and reduces galling\u003c\/li\u003e\n  \u003cli\u003eMaximum locking torque of 9 inch-pounds with minimum breakaway torque of 1.50 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e13-1\/4 free coils at 3D length-to-diameter ratio for full thread engagement\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.205 to 0.220 inches for proper fit in standard tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw-locking insert for tapped holes requiring 8-32 UNC internal threads in metal or engineered plastic parent materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a correctly sized HELI-COIL tap and installation tool matched to the 8-32 UNC thread size and 3D insert length. Power down or de-energize any equipment before performing thread repair or insert installation on live assemblies. The tangless design requires a tangless-compatible installation mandrel  -  do not attempt installation with tools designed for tang-style inserts.
