HSS UNC (Unified National Coarse) and NC (National Coarse) Dies are robust threading tools engineered for cutting, repairing, and restoring coarse‑pitch imperial external threads. Manufactured from high‑speed steel, these dies offer superior durability, hardness, and wear resistance, ensuring consistent performance even in heavy‑duty workshop and industrial applications. Coarse‑pitch imperial threads are widely used across construction, automotive, machinery repair, fabrication, and general engineering because of their higher tolerance to dirt, damage, and repeated assembly. UNC/NC threads also provide excellent resistance against stripping and are ideal for softer materials or environments where fastener engagement needs to be reliable and forgiving. With precision‑ground cutting edges for smooth chip evacuation and clean thread profiles, HSS UNC/NC Dies deliver dependable results on common workshop metals including mild steel, stainless steel, aluminium, and brass. A range of outside diameters ensures compatibility with standard die stocks and various threading setups, making them suitable for both onsite and workshop‑based repairs.
