Manufactured from 304 stainless steel with a bright, uncoated finish, this insert accepts an M20 x 2.5 thread and measures 1.1811 inches (30 mm) in overall length, placing it in the 1-1\/2D length-to-diameter category. Free running inserts allow standard fasteners to thread through without interference, making them suitable for general-purpose thread repair and thread reinforcement applications. Installation is performed by licensed mechanics, maintenance technicians, and MRO professionals using a dedicated HELI-COIL installation tool.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in thread repair and thread reinforcement applications across industrial, mechanical, and manufacturing environments. It suits situations where an M20 x 2.5 metric coarse thread has been stripped, damaged, or needs upgrading in a softer parent material such as aluminum or cast iron. The 30 mm overall length and 9-7\/8 free coils provide consistent thread engagement depth appropriate for standard fastener loads in both light and heavy assemblies. This single-insert package is suited for low-volume repair work or replacement stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20 x 2.5 metric coarse thread size for broad fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e30 mm (1.1811 inches) overall insert length at a 1-1\/2D length-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction for corrosion resistance in service environments\u003c\/li\u003e\n  \u003cli\u003eTanged design for controlled installation with standard HELI-COIL insertion tools\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish with 9-7\/8 free coils for consistent thread form\u003c\/li\u003e\n  \u003cli\u003eFree running style allows standard fastener engagement without interference fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style thread repair insert for parent materials tapped to accept an M20 x 2.5 metric coarse HELI-COIL insert using the corresponding installation tool and tap size specified for this insert series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires drilling out the damaged thread to the correct oversize diameter, tapping the bore with the specified HELI-COIL tap, and driving the insert with the matching installation tool.
