Nuts are fastening components used with bolts or screws in all manufacturing machinery. Available in various materials including carbon steel, stainless steel, and non-ferrous metals like copper.

The nut connects mechanical equipment through internal threads, matching with bolts of identical specifications. For example, M4-P0.7 nuts pair exclusively with M4-P0.7 bolts (M4 indicates ~4mm inner diameter, 0.7mm thread pitch). Similarly, 1/4-20 nuts match 1/4-20 screws (0.25" inner diameter, 20 threads per inch).

• Copper material nuts including zinc copper alloy, knurled copper, and injection copper nuts
• Stainless steel variants
• Specialty nuts: round, ring, butterfly, self-locking, four-claw, and safety nuts
• DISC-LOCK nuts with wedge design for vibration resistance
• Hexagonal flange face lock nuts in fine teeth configurations
• Welded nuts: square, hexagon, and inserted round types

• Aluminum: Excellent conductivity but requires careful machining
• Titanium: Requires EDM machining with deionized water cooling
• Steel: High strength, often processed with wire cutting machines
• Brass: High tensile strength but needs slow cutting speeds

• Reusable medium carbon steel construction
• Easy installation and disassembly
• Gasket-free design
• Compatible with Class 8.8 and 10.9 high strength bolts
