Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect torque, leading to under-tightening or over-tightening.Consult engineering drawings or a torque chart for the specific application and material to determine the correct tightening torque.
Cross-threading the screw by forcing it into the mating thread.Always start threading by hand to ensure proper alignment before applying any torque.

Common Applications

  • Structural assembly in corrosive environments
  • Machinery and equipment manufacturing
  • Marine and offshore applications

⚠️ Engineering Warnings

  • Ensure compatibility with the mating thread or nut before installation.
  • Avoid using excessive force, which can damage threads or compromise the fastener's integrity.
