Product Description

The HELI-COIL 5403-16 is a complete threaded insert thread repair kit designed to restore damaged or stripped M16 x 2.00 metric coarse threads to full load-bearing strength. The kit includes all tooling required for a complete repair: a drill, tap, installation tool (part number 3747-16), and tang removal tool, along with 6 stainless wire thread inserts at a 24mm insert length. This kit is suited for field repair and shop use wherever M16 metric coarse threads have been compromised in metal components. The kit weighs 1.25 pounds and is ready to use straight from the package.

This kit is intended for use by machinists, mechanics, and maintenance technicians working on equipment with M16 metric coarse threaded fastener locations. Common applications include engine components, industrial machinery, automotive assemblies, and structural hardware where a stripped or cross-threaded bore needs to be brought back to service-ready condition. The 24mm insert length provides full thread engagement suitable for higher-load fastener applications.

Installation Notes

Thread repair should be performed by a qualified mechanic or machinist familiar with insert installation procedures. Power down or de-energize any equipment before beginning thread repair work. Use the included drill and tap in the correct sequence before driving the insert with the provided installation tool, then remove the tang using the included tang removal tool after installation is complete. Follow applicable equipment manufacturer service procedures and torque specifications for the reassembled fastener joint.
