Nuts are essential fastening components used in conjunction 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 precisely with bolts of the same specifications. For example, an M4-P0.7 nut connects only with M4-P0.7 bolts (M4 indicates ~4mm inner diameter, 0.7 indicates 0.7mm thread pitch). Similarly, 1/4-20 nuts match with 1/4-20 screws (0.25" inner diameter, 20 threads per inch).

• Stainless steel applications
• Copper material applications including knurled, embedded, and injection copper nuts
• Zinc copper alloy nuts
• Various specialized nuts: round nuts with slots/holes, welded nuts, self-locking nuts, locking nuts, four-claw nuts, driving nuts, safety nuts, thin rod connection nuts, and more
• DISC-LOCK nuts feature a two-part design with staggered cams for vibration-resistant locking
• Fine teeth all metal and non-metal insert hexagonal flange face lock nuts

• Aluminum: Excellent thermal/electrical conductivity but soft; requires proper processing
• Titanium: Requires EDM machining with deionized water medium
• Steel: Very strong; often processed with wire cutting machines; heat management required
• Brass: High tensile strength; requires slow cutting speeds

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