Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force leading to thread stripping or material deformation.Apply torque gradually and refer to material-specific torque charts if available. For nylon, avoid overtightening which can compromise structural integrity.
Incorrectly matching screw size to the mating thread.Always verify that the M8 thread size of the cap screw is compatible with the M8 tapped hole or nut being used.

Common Applications

  • Electrical enclosure assembly
  • Chemical processing equipment
  • Lightweight structural components
  • Marine applications

⚠️ Engineering Warnings

  • Nylon has a lower tensile strength and temperature resistance compared to metallic fasteners. Do not use in high-stress or high-temperature applications.
  • While resistant to many chemicals, prolonged exposure to strong acids or bases may degrade the nylon material.
