Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized or oversized driving tool, leading to cam-out or fastener damage.Always use a hex driver that precisely matches the head width of the cap screw.
Applying excessive torque, which can strip threads or cause fastener fatigue.Adhere to the manufacturer's or engineering design's recommended torque specifications.
Installing in a dirty or damaged threaded hole, compromising joint integrity.Thoroughly inspect and clean all mating threads before assembly.

Common Applications

  • Structural assembly in corrosive environments
  • Marine and offshore equipment
  • Food and beverage processing machinery

⚠️ Engineering Warnings

  • Ensure compatibility with mating materials to prevent galvanic corrosion.
  • Always consult engineering specifications for proper torque values and thread engagement.
