Product Description

Nuts are fastening components that screw together with bolts or screws to secure parts in machinery and equipment. They are essential for all manufacturing processes. Based on material, nuts are categorized 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 match with 1/4-20 screws (0.25" inner diameter, 20 threads per inch).

Applications
  • Copper material: Zinc copper alloy nuts, etc.
  • Stainless steel: Copper nut, inlaid copper nut, knurled copper nut, embedded copper nut, injection copper nut
  • Round nut, ring nut, butterfly nut
  • DISC-LOCK lock nut: Two-part design with staggered CAMs for vibration resistance
  • Self-locking nut, locking nut, four-claw nut, driving nut safety nut
  • Thin rod screw connection nut, self-locking hexagonal cap nut
  • Special anchor screw nut, hexagonal crown thin nut, suspension ring nut
  • Welded square nut, welded hexagon nut, fastening nut, inserted round nut
  • Fine teeth all metal hexagonal flange face lock nut
  • Round nut with slot, round nut with hole on side/end, small round nut
Material Specifications
Aluminum Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing.
