Nuts are fasteners that screw together with bolts or screws to create secure connections. Essential for 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 only connects 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 (0.25" inner diameter, 20 threads per inch).

• Stainless Steel: Self-locking nuts, locking nuts, four-claw nuts, driving nuts, safety nuts, thin rod screw connection nuts, flange face lock nuts
• Metal: Zinc copper alloy nuts
• Copper: Copper nuts, knurled copper nuts, embedded copper nuts, injection copper nuts
• Specialty: DISC-LOCK nuts feature interlocking cam mechanisms that maintain tension during vibration for perfect locking

• Aluminum: Excellent conductivity but soft; requires careful processing
• Titanium: Best machined with EDM using deionized water for heat control
• Steel: High strength; wire cutting often preferred for complex features
• Brass: High tensile strength but requires slow cutting speeds
