Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using steel fasteners in brass assemblies, leading to galvanic corrosion.Always use brass or compatible fasteners with brass components to prevent premature degradation.
Overtightening the screw, which can strip the threads or damage the mating material.Use a torque wrench to tighten fasteners to the manufacturer's recommended torque specifications.

Common Applications

  • Marine hardware and fittings
  • Electrical grounding and busbar connections
  • Corrosive industrial environments

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid excessive force during installation.
  • While resistant to many chemicals, consult compatibility charts for specific aggressive media.
