The insert measures M4 x 0.7 metric coarse thread with an overall length of 0.1575 inches (4.0 mm), making it a 1D length-to-diameter ratio insert suited for thin or space-constrained base materials. Manufactured from 304 stainless steel with a bright, uncoated finish, it delivers corrosion resistance without surface treatment interference. Installed by maintenance technicians, machinists, and trade mechanics, the tanged design aids installation with a standard HELI-COIL installation tool.\u003c\/p\u003e\n\u003cp\u003eThis insert is used wherever a metric coarse M4 thread must be formed or reclaimed in aluminum, cast iron, magnesium, plastic, or other materials with lower inherent thread strength. Typical applications include light equipment assemblies, automotive components, HVAC equipment housings, electrical enclosures, and precision assemblies where thread pullout or cross-threading has compromised the original bore. The bright stainless finish keeps it suitable for exposed or mildly corrosive environments. This item is sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM4 x 0.7 metric coarse thread profile for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eOverall insert length of 0.1575 inches (4.0 mm) with a 1D length-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eTanged design for controlled installation using a compatible HELI-COIL driver tool\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish with 3-5\/8 free coils for consistent locking engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style free running threaded insert for use in any parent material requiring an M4 x 0.7 metric coarse thread form or thread repair.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires drilling and tapping the parent material to the correct HELI-COIL oversize tap dimension before driving the insert with a properly sized installation tool. Power down or de-energize any equipment before performing thread repair on electrical enclosures or mechanical assemblies. After installation, the tang must be broken off using a tang break-off tool to complete the installation.
