Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or component damage.Always adhere to recommended torque specifications and use calibrated torque tools for accurate tightening.
Cross-threading the screw by not starting it straight by hand.Initiate thread engagement by hand for at least two full turns before applying any tool to ensure correct alignment.

Common Applications

  • Electrical and electronic enclosures
  • Marine hardware and fittings
  • Decorative architectural elements
  • Corrosive environment assemblies

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid overtightening to prevent thread damage.
  • Ensure compatibility with mating threads; this is an M9 metric thread.
