Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel fastener in a corrosive environment where brass is specified.Always select fasteners made from materials appropriate for the operating environment's corrosive potential, such as brass for its superior resistance.
Applying excessive torque which can strip threads or deform the fastener.Consult design specifications for correct torque values and use a calibrated torque wrench for accurate tightening.

Common Applications

  • Marine hardware and fittings
  • Electrical and electronic assemblies requiring non-magnetic properties
  • Chemical processing equipment connections

⚠️ Engineering Warnings

  • Brass is a softer material than steel; do not use in high-stress applications where shear strength is paramount.
  • While corrosion-resistant, brass can still be affected by certain aggressive chemicals; verify compatibility for specific applications.
