Nuts are fastening components that screw together with bolts or screws to secure mechanical equipment. They are essential for all manufacturing machinery and are categorized by material into carbon steel, stainless steel, and non-ferrous metals (such as copper).

The nut connects mechanical equipment through its internal thread, matching with bolts of identical specifications. For example, an M4-P0.7 nut can only connect with M4-P0.7 series bolts (where M4 indicates an inner diameter of approximately 4mm and 0.7 represents a 0.7mm thread pitch). Similarly, a 1/4-20 nut matches with 1/4-20 screws (1/4 indicating a 0.25-inch inner diameter and 20 representing 20 threads per inch).

• Stainless Steel: Welded square nuts, hexagon nuts, fastening nuts, inserted round nuts, slotted round nuts, side-hole round nuts, end-hole round nuts, small round nuts, ring nuts, butterfly nuts, self-locking nuts, locking nuts, four-claw nuts, driving nuts, safety nuts, thin rod screw connection nuts, hexagonal cap nuts, anchor screw nuts, crown thin nuts, suspension ring nuts, flange face lock nuts.
• Copper Material: Copper nuts, inlaid copper nuts, knurled copper nuts, embedded copper nuts, injection copper nuts.
• Metal: Zinc copper alloy nuts.
• DISC-LOCK Nuts: Composed of two parts with staggered cams, these nuts use an internal wedge design for vibration-resistant locking.

• Aluminum: Excellent thermal/electrical conductivity but soft; requires careful machining.
• Titanium: EDM machining recommended; requires deionized water for heat control.
• Steel: Strong material; wire cutting often preferred for complex features.
• Brass: High tensile strength; requires slow cutting speeds.

• Easy to install and disassemble
• Gasket-free design
