Dear Manager,

This is Jane from Lituo Hardware in China.

We know that Gold processing environments are brutal on fasteners — cyanide leaching, sulfuric acid, abrasive slurry, and continuous vibration. Standard hardware simply doesn't last.

We supply heavy-duty fasteners engineered for mining and mineral processing:

For Leaching & Processing Plants:

• 1.Duplex / Super Duplex Stainless Steel Bolts & Nuts — Exceptional resistance to cyanide and chloride stress corrosion cracking; ideal for leach tanks, agitators, and pregnant solution piping
• 
  
• 2.Hastelloy / 316L Stud Bolts — For acid service and high-temperature autoclave applications
• Hot-Dip Galvanized Hex Bolts (Grade 8.8 / 10.9) — Structural connections for tank supports, walkways, and steel frameworks

For Crushing & Grinding:

• 1.High-Tensile Socket Head Screws (Grade 12.9) — Crusher jaw plates, mill liners, screen decks; withstand constant impact and vibration
• 
  
• 2.Nord-Lock / Wedge-Lock Washers — Prevent loosening under extreme dynamic loads

For Conveyor & Material Handling:

• 1.Heavy Hex Structural Bolts (ASTM A325 / A490) — Conveyor truss and transfer tower assembly
• 
  
• 2.Self-Drilling Screws with Ruspert Coating — Conveyor covers, guards, and non-structural enclosures

Why mining operations choose us:

• 
  
• 1.Custom sizing and special coatings available (PTFE / Xylan / Geomet for extreme chemical resistance)
• 
  
• 2.Stocked sizes in Grades 8.8, 10.9, 12.9 and A2 / A4 stainless
• 
  
• 3.Proven supply to mining projects in Africa, South America, and Southeast Asia

Could you share what part of the gold recovery circuit you're involved with — crushing, leaching, or refinery? 

I'd be happy to recommend the right fastener grades for your specific application.

Best regards,

Jane
