Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size wrench, leading to stripped hex heads.Always use a wrench or socket that precisely matches the 23mm head width for optimal engagement and torque transfer.
Over-tightening, which can damage the brass threads or the mating material.Apply torque gradually and stop once the screw is snug. Consult torque specifications if available for the specific application.

Common Applications

  • Marine hardware and fittings
  • Electrical enclosures and grounding components
  • Decorative architectural elements
  • Corrosion-resistant assemblies

⚠️ Engineering Warnings

  • Brass is a softer metal than steel; avoid excessive force that could strip threads or deform the head.
  • While corrosion-resistant, prolonged exposure to certain aggressive chemicals may degrade brass over time. Verify material compatibility for extreme environments.
