PowerCoil Thread Repair Kits | UNF (Multiple Sizes)

Permanently Repair and Strengthen Damaged Fine Threads.

The Bordo PowerCoil UNF Thread Repair Kit is the industry-standard solution for salvaging stripped, worn, or damaged internal fine threads. Instead of scrapping expensive castings, engine components, or precision machinery parts, PowerCoil allows you to quickly tap out the damaged thread and install a precision-engineered wire insert. The result is a renewed internal thread that matches the original fastener size while offering superior structural strength and wear resistance.

Manufactured from premium grade stainless steel, the diamond-profile wire inserts form an incredibly durable internal thread that resists corrosion, cross-threading, and thermal strip-out. Because UNF threads are frequently utilized in high-stress, high-vibration automotive, aerospace, and precision engineering applications, this kit is an essential asset for any workshop or maintenance department demanding absolute reliability.

Key Features

• Superior Thread Strength: Precision stainless steel inserts distribute structural loads more evenly across the parent material, providing a higher load capacity than the original factory thread.
• Original Bolt Retention: Repairs the stripped thread back to its exact original specification, allowing you to reuse your original high-tensile UNF fasteners and components.
• Exceptional Vibe & Wear Resistance: High-quality wire construction offers excellent resistance to wear, corrosion, and high operating temperatures, making it perfect for critical fine-thread assemblies.
• Cost-Effective Maintenance: Minimizes costly industrial downtime and eliminates the need for expensive replacement parts, welding, or oversized custom studs.

Typical Kit Contents

Each workshop-ready kit is securely packed and typically contains the essential precision tooling required to complete a professional, long-lasting repair:

• Precision STI (Screw Thread Insert) Tap: Engineered to cut the perfect oversize fine-thread path for the insert.
• High-Quality Stainless Steel Wire Inserts: Precision diamond-profile inserts to completely rebuild your internal threads.
• Installation Tool & Tang Break Tool: For smooth, controlled insert deployment and clean tang removal (included where applicable by size).
