Nuts are fastening components used with bolts or screws in all manufacturing machinery. They are categorized by material into carbon steel, stainless steel, and non-ferrous metals (such as copper).
The nut connects mechanical equipment through internal threads, matching with bolts of identical specifications. For example, an M4-P0.7 nut connects only with M4-P0.7 bolts (where M4 indicates ~4mm inner diameter and 0.7mm thread pitch). Similarly, 1/4-20 nuts pair exclusively with 1/4-20 screws.

- Specialty nuts: round, ring, butterfly, welded, self-locking, and safety nuts
- DISC-LOCK nuts with wedge design for vibration resistance
- Flange face lock nuts (metal and non-metal insert types)
| Material | Properties |
