Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force on brass, leading to thread stripping or deformation.Apply appropriate torque based on the application's requirements and material strength. Consult torque charts if necessary.
Using the incorrect tool size on the hex head, causing damage.Ensure the wrench or socket fits snugly on the 24mm hex head to prevent slippage and damage.

Common Applications

  • Electrical connector assemblies
  • Marine hardware and fittings
  • Corrosion-resistant fixtures

⚠️ Engineering Warnings

  • Brass is softer than steel; avoid over-torquing which can strip threads.
  • While corrosion-resistant, extreme chemical exposure may degrade brass over time.
