Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect tool size for the hex head, leading to stripping.Always use a wrench or socket that precisely fits the 34mm hex head to prevent damage.
Cross-threading the screw during installation.Start threading by hand to ensure proper alignment before applying torque. If resistance is met, back out and re-align.

Common Applications

  • Marine hardware and fittings
  • Electrical grounding and connection points
  • Decorative architectural elements
  • Corrosive industrial environments

⚠️ Engineering Warnings

  • Brass is a softer metal than steel; excessive force can lead to deformation or stripping of threads.
  • While corrosion-resistant, prolonged exposure to certain aggressive chemicals may degrade brass over time.
