Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening brass screws, which can strip threads or deform the material.Adhere to torque specifications; use a torque wrench for precision. Brass is softer than steel, requiring a gentler approach.
Using brass screws in high-stress structural applications where steel is recommended.Assess the load requirements. Brass is suitable for moderate loads and corrosive environments, not primary structural support.

Common Applications

  • Marine hardware and fittings
  • Electrical connectors and enclosures
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Brass can be susceptible to dezincification in certain aggressive chemical or high-temperature environments.
  • Ensure compatibility with mating materials to prevent galvanic corrosion if used in dissimilar metal assemblies.
