Precision Thread Restoration. Stronger Than the Original.
The PowerCoil Metric Coarse Wire Thread Repair Kits provide everything you need to permanently salvage stripped, worn, or damaged internal threads. Manufactured from high-quality diamond-profile stainless steel wire, these inserts wind into a tapped hole to create a highly durable, wear-resistant internal thread that resists both corrosion and intense thermal stress. Perfect for automotive maintenance, industrial machinery overhaul, and general engineering, these complete kits replace weak, cross-threaded holes with strong, premium-grade fasteners, ensuring your workshop assemblies stay rock-solid under load.
Key Features
- Complete Master Kits: Each kit includes the correct HSS STI intermediate tap, a specialized installation tool, a tang break tool, a corresponding HSS jobber drill bit, and a pack of precision wire inserts.
- Premium Stainless Construction: Inserts are forged from high-tensile stainless steel wire to protect assemblies against future stripping, galling, and high-fretting wear.
- Rigid Thread Alignment: Once installed, the spring-like expansion of the wire coils locks them permanently into the parent material, ensuring balanced load distribution.
- Comprehensive Metric Range: Available in precise sizing structures ranging from M3 up to M16 coarse pitches to suit a massive array of workshop applications.
