Core Advantages

1. Excellent Rust & Corrosion Resistance for Versatile Environments
   
   
   As classic austenitic stainless steel, SS304 features standard chromium-nickel composition with inherent anti-rust property. It resists indoor humidity, mist, rainwater, mild acid & alkali, and oil fumes far better than carbon steel galvanized nuts which peel and rust quickly. No coating shedding will contaminate equipment or workpieces.
   
   
   Note: Not recommended for coastal heavy salt spray areas and strong chemical acid/alkali working conditions; SS316 is required for such harsh environments.
2. Balanced Mechanical Performance, Firm Fastening, Anti-stripping & Anti-cracking
   
   
   Moderate hardness and toughness prevent corner cracking, fracture and thread slipping during tightening. Precision metric internal threads fit perfectly with hex bolts for tight meshing, maintaining stable fastening under continuous vibration. It withstands regular load and lasts well after repeated assembly and disassembly.
3. High Universal Compatibility & Standard Specification
   
   
   Manufactured strictly in accordance with GB/T 6170 metric hex nut standard. Full sizes from M2 to M30 are available. Matches seamlessly with SS304 hex bolts, socket head screws, flat washers and spring washers. Compatible with open-end wrenches, socket wrenches and torque wrenches for easy installation.
4. Food-Grade Safe & Sanitary

   
   

   SS304 is approved for food contact. Non-toxic, odorless and free of harmful heavy metal precipitation. Easy to wipe clean from grease, ideal for catering and drinking equipment assembly.
