Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force leading to thread stripping or component damage.Apply torque gradually and refer to recommended torque specifications for the mating components and material.
Selecting the wrong screw size or thread pitch for the application.Verify the M15 thread size and 13mm length are compatible with the intended fastening scenario before installation.

Common Applications

  • Electrical conductivity applications
  • Marine and offshore hardware
  • Corrosive chemical environments

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid over-torqueing to prevent thread damage.
  • Ensure the application does not require the high tensile strength of steel fasteners.
