Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard steel tools which can cause galling on brass threads.Utilize brass or coated tools to minimize the risk of thread damage and galling.
Over-torquing the screw, which can strip threads or deform the component.Consult torque charts for brass fasteners or use a calibrated torque wrench to apply the recommended torque.

Common Applications

  • Marine hardware and fixtures
  • Chemical processing equipment
  • Outdoor electrical enclosures
  • Architectural metalwork

⚠️ Engineering Warnings

  • Brass is a softer metal; avoid excessive force that could damage threads.
  • Not suitable for high-tensile structural applications where steel fasteners are required.
