Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped head damage.Always use a wrench that precisely fits the 17mm head width to prevent damage and ensure proper torque.
Cross-threading the screw during installation, damaging both the screw and the receiving threads.Start threading by hand to confirm proper alignment before applying any torque.

Common Applications

  • Marine hardware and fittings
  • Electrical grounding and connections
  • Decorative architectural elements
  • Plumbing fixtures
  • Corrosive environment assemblies

⚠️ Engineering Warnings

  • Brass is a softer metal than steel; avoid excessive force that could strip threads or damage the head.
  • While corrosion-resistant, brass can still oxidize over time. Consider appropriate coatings or regular maintenance for prolonged aesthetic appearance.
