Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect thread pitch for the mating component.Verify that the M13 thread pitch of the cap screw precisely matches the internal or external thread it will engage with.
Applying excessive force, leading to thread stripping or component damage.Use a torque wrench set to the recommended specification for brass fasteners to avoid over-tightening and potential damage.

Common Applications

  • Electrical connections and enclosures
  • Marine hardware and fittings
  • Chemical processing equipment
  • Corrosive environment assemblies

⚠️ Engineering Warnings

  • Brass can gall under high stress; ensure proper lubrication if high torque is required.
  • While corrosion-resistant, brass may react with certain aggressive chemicals; consult material compatibility charts.
