Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-torquing the titanium screw.Always use a calibrated torque wrench and adhere to the specific torque values recommended for the application and mating materials to prevent thread stripping or fastener fracture.
Using incompatible tools for tightening.Utilize tools designed for hex head fasteners with the correct socket size (M14 for this screw) to ensure proper engagement and prevent cam-out or damage to the head.

Common Applications

  • Aerospace structural components
  • Medical implants and surgical instrumentation
  • Marine and offshore equipment
