Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a tool that is not the correct size for the hex head, leading to stripping.Always use a properly sized metric socket or wrench that fits snugly onto the hex head to ensure efficient torque transfer and prevent damage.
Applying excessive torque, which can lead to thread damage or fastener failure.Consult engineering specifications or use a torque wrench to tighten the screw to the recommended torque value for the specific application.

Common Applications

  • Marine and offshore equipment construction
  • Chemical processing plant assembly
  • Structural steel connections

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) when handling fasteners.
  • Ensure compatibility of mating materials to prevent galvanic corrosion.
