Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force leading to thread stripping.Consult torque specifications for brass fasteners and use a calibrated torque wrench for precise tightening.
Not verifying thread compatibility with the mating component.Always confirm that the M15 thread specification matches the intended receiving thread.

Common Applications

  • Marine hardware and fittings
  • Chemical processing equipment
  • Electrical enclosures and grounding
  • Food processing machinery
  • Corrosive environment assemblies

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid using excessive torque which can damage threads or the fastener.
  • While brass offers good corrosion resistance, it may not be suitable for all highly aggressive chemical environments. Consult material compatibility charts.
