Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or material fatigue.Consult torque charts for brass fasteners of this size and material, and utilize a torque wrench for precise application.
Using the wrong size wrench, which can damage the hex head or lead to slippage.Always use a wrench or socket that precisely fits the 34mm head width to ensure proper engagement and prevent damage.

Common Applications

  • Marine hardware and fittings
  • Electrical enclosures and components
  • Decorative architectural elements
  • Food processing equipment
  • Chemical processing plants

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid using in high-stress applications where significant shear or tensile strength is required.
  • While corrosion-resistant, prolonged exposure to certain aggressive chemicals or environments may still cause degradation. Verify compatibility.
