Carbon Steel Hex Rethreading Dies – Metric Coarse Thread

Restore damaged external threads quickly and reliably with our premium carbon steel hex rethreading dies. Designed for metric coarse threads (M series), these dies are an essential tool for ship engine rooms, deck maintenance, and general vessel repair work. The high-carbon steel construction ensures durability and resistance to wear, even under demanding marine conditions.

Each die features precision-ground cutting edges that produce clean, accurate threads, allowing you to salvage expensive bolts, studs, and other fasteners instead of replacing them. The hexagonal shape fits standard wrenches or die stocks, enabling simple manual operation without special machinery. This makes them a practical, cost-effective solution for onboard repairs where quick turnaround is critical.

Available in a range of common metric coarse sizes, these rethreading dies are a must-have addition to any ship's tool inventory. Whether you are chasing a damaged thread after accidental cross-threading or preparing a new stud, these dies deliver consistent performance and long service life.
